Iowa (聆听i/ˈəwə/)[5][6][7] is a state in the Midwestern United States, bordered by the Mississippi River to the east and the Missouri River and Big Sioux River英语Big Sioux River to the west. It is bordered by six states: Wisconsin to the northeast, Illinois to the east, Missouri to the south, Nebraska to the west, South Dakota to the northwest, and Minnesota to the north.

In colonial times, Iowa was a part of French Louisiana and Spanish Louisiana英语Louisiana (New Spain); its state flag is patterned after the flag of France. After the Louisiana Purchase, people laid the foundation for an agriculture-based economy in the heart of the Corn Belt.[8]

In the latter half of the 20th century, Iowa's agricultural economy made the transition to a diversified economy of advanced manufacturing, processing, financial services, information technology, biotechnology, and green energy production.[9][10] Iowa is the 26th most extensive in land area and the 30th most populous of the 50 U.S states. The state's capital, most populous city, and largest metropolitan area fully located within the state is Des Moines. A portion of the larger Omaha, Nebraska, metropolitan area英语Omaha–Council Bluffs metropolitan area extends into three counties of southwest Iowa.[11] Iowa has been listed as one of the safest states in which to live.[12]

Etymology

编辑

Iowa derives its name from the Ioway英语Iowa people people, one of the many Native American tribes that occupied the state at the time of European exploration.[13]

Geography

Boundaries

编辑
 
Topography of Iowa, with counties and major streams

Iowa is bordered by the Mississippi River on the east and the Missouri River and the Big Sioux River英语Big Sioux River on the west. The northern boundary is a line along 43 degrees, 30 minutes north latitude.[14][note 1] The southern border is the Des Moines River and a not-quite-straight line along approximately 40 degrees 35 minutes north, as decided by the U.S. Supreme Court in Missouri v. Iowa英语State of Missouri v. State of Iowa (1849) (1849) after a standoff between Missouri and Iowa known as the Honey War英语Honey War.[15][16]

Iowa is the only state whose east and west borders are formed entirely by rivers.[17]

Iowa has 99 counties, but 100 county seats because Lee County has two. The state capital, Des Moines, is in Polk County.[18]

Geology and terrain

编辑
 
DeSoto Lake英语DeSoto Lake (Iowa) at DeSoto National Wildlife Refuge英语DeSoto National Wildlife Refuge
 
Fountain Springs Park英语Fountain Springs Park in Delaware County, Iowa

Iowa's bedrock geology generally increases in age from west to east. In northwest Iowa, Cretaceous bedrock can be 74 million years old; in eastern Iowa Cambrian bedrock dates to c. 500 million years ago.[19]

Iowa is generally not flat; most of the state consists of rolling hills. Iowa can be divided into eight landforms based on glaciation, soils, topography, and river drainage.[20] Loess hills lie along the western border of the state, some of which are several hundred feet thick.[21] Northeast Iowa along the Upper Mississippi River英语Upper Mississippi River is part of the Driftless Area英语Driftless Area, consisting of steep hills and valleys which appear almost mountainous.

Several natural lakes exist, most notably Spirit Lake英语Spirit Lake (Iowa), West Okoboji Lake英语West Okoboji Lake, and East Okoboji Lake英语East Okoboji Lake in northwest Iowa (see Iowa Great Lakes英语Iowa Great Lakes). To the east lies Clear Lake英语Clear Lake (Iowa). Man-made lakes include Lake Odessa,[22] Saylorville Lake英语Saylorville Lake, Lake Red Rock英语Lake Red Rock (Des Moines River), Coralville Lake英语Coralville Lake, Lake MacBride, and Rathbun Lake. The state's northwest area has many remnants of the once common wetlands, such as Barringer Slough英语Barringer Slough.

Ecology and environment

编辑
 
Landforms of Iowa, based on Prior (1991)

Iowa's natural vegetation is tallgrass prairie英语tallgrass prairie and savanna in upland areas, with dense forest and wetlands in flood plains and protected river valleys, and pothole wetlands in northern prairie areas.[20] Most of Iowa is used for agriculture; crops cover 60% of the state, grasslands (mostly pasture and hay with some prairie and wetland) cover 30%, and forests cover 7%; urban areas and water cover another 1% each.[23]

The southern part of Iowa is categorised as the Central forest-grasslands transition英语Central forest-grasslands transition ecoregion. The Northern, drier part of Iowa is categorised as the Central tall grasslands英语Central tall grasslands and is thus considered to be part of the Great Plains.

There is a dearth of natural areas in Iowa; less than 1% of the tallgrass prairie that once covered most of Iowa remains intact; only about 5% of the state's prairie pothole wetlands remain, and most of the original forest has been lost.[24] 截至2005年 (2005-Missing required parameter 1=month!) Iowa ranked 49th of U.S. states in public land holdings.[25] Threatened or endangered animals in Iowa include the interior least tern英语least tern, piping plover, Indiana bat英语Indiana bat, pallid sturgeon, the Iowa Pleistocene land snail英语Discus macclintocki, Higgins' eye pearly mussel, and the Topeka shiner英语Topeka shiner.[26] Endangered or threatened plants include western prairie fringed orchid英语western prairie fringed orchid, eastern prairie fringed orchid英语eastern prairie fringed orchid, Mead's milkweed英语Mead's milkweed, prairie bush clover英语prairie bush clover, and northern wild monkshood英语northern wild monkshood.[27]

There is little proof to suggest that the explosion in the number of high-density livestock facilities in Iowa has led to increased rural water contamination and a decline in air quality.[28] In fact, covered manure storage in modern barns prevent that manure from washing away into surface water, as it does in open lots as snow melts and thunderstorms occur.

Other factors negatively affecting Iowa's environment include the extensive use of older coal-fired power plants,[29] fertilizer and pesticide runoff from crop production,[30] and diminishment of the Jordan Aquifer英语Jordan Aquifer.[31]

Climate

Köppen climate types in Iowa
 
Iowa annual rainfall, in inches

Iowa has a humid continental climate throughout the state (Köppen climate classification Dfa) with extremes of both heat and cold. The average annual temperature at Des Moines is 50 °F(10 °C); for some locations in the north the figure is under 45 °F(7 °C), while Keokuk, on the Mississippi River, averages 52 °F(11 °C). Winters are often harsh and snowfall is common.

Spring ushers in the beginning of the severe weather英语severe weather season. Iowa averages about 50 days of thunderstorm activity per year.[32] The 30 year annual average Tornadoes in Iowa is 47.[33] In 2008英语Late-May 2008 tornado outbreak sequence, twelve people were killed by tornadoes in Iowa, making it the deadliest year since 1968英语May 1968 tornado outbreak and also the second most tornadoes in a year with 105, matching the total from 2001.[34]

Iowa summers are known for heat and humidity, with daytime temperatures sometimes near 90 °F(32 °C) and occasionally exceeding 100 °F(38 °C). Average winters in the state have been known to drop well below freezing, even dropping below −18 °F(−28 °C). Iowa's all-time hottest temperature of 118 °F(48 °C) was recorded at Keokuk on July 20, 1934; the all-time lowest temperature of −47 °F(−44 °C) was recorded at Elkader on February 3, 1996.

Iowa has a relatively smooth gradient of varying precipitation across the state, with areas in the southeast of the state receiving an average of over 38英寸(97厘米) of rain annually, and the northwest of the state receiving less than 28英寸(71厘米).[41] The pattern of precipitation across Iowa is seasonal, with more rain falling in the summer months. Virtually statewide, the driest month is January or February, and the wettest month is June, owing to frequent showers and thunderstorms, some of which produce hail, damaging winds and/or tornadoes. In Des Moines, roughly in the center of the state, over two-thirds of the 34.72英寸(88.2厘米) of rain falls from April through September, and about half of the average annual precipitation falls from May through August, peaking in June.[42]

Prehistory

编辑
 
Excavation of the 3,800-year-old Edgewater Park Site英语Edgewater Park Site

When American Indians first arrived in what is now Iowa more than 13,000 years ago, they were hunters and gatherers living in a Pleistocene glacial landscape. By the time European explorers and traders visited Iowa, American Indians were largely settled farmers with complex economic, social, and political systems. This transformation happened gradually. During the Archaic period英语Archaic period in North America (10,500–2,800 years ago), American Indians adapted to local environments and ecosystems, slowly becoming more sedentary as populations increased.[43]

More than 3,000 years ago, during the Late Archaic period, American Indians in Iowa began utilizing domesticated plants. The subsequent Woodland period saw an increased reliance on agriculture and social complexity, with increased use of mounds, ceramics, and specialized subsistence. During the Late Prehistoric period (beginning about AD 900) increased use of maize and social changes led to social flourishing and nucleated settlements.[43]

The arrival of European trade goods and diseases in the Protohistoric period led to dramatic population shifts and economic and social upheaval, with the arrival of new tribes and early European explorers and traders. There were numerous Indian tribes living in Iowa at the time of early European exploration. Tribes which were probably descendants of the prehistoric Oneota英语Oneota include the Dakota, Ho-Chunk英语Ho-Chunk, Ioway英语Ioway, and Otoe英语Otoe (tribe). Tribes which arrived in Iowa in the late prehistoric or protohistoric periods include the Illiniwek, Meskwaki, Omaha, and Sauk英语Sauk people.[43]

History

Early exploration and trade, 1673–1808

编辑
 
Iowa in 1718 with the modern state area highlighted

The first known European explorers to document Iowa were Jacques Marquette英语Jacques Marquette and Louis Jolliet英语Louis Jolliet who traveled the Mississippi River in 1673 documenting several Indian villages on the Iowa side.[44][45] The area of Iowa was claimed for France and remained a French territory until 1763. The French, before their impending defeat in the French and Indian War, transferred ownership to their ally, Spain.[46] Spain practiced very loose control over the Iowa region, granting trading licenses to French and British traders, who established trading posts along the Mississippi and Des Moines Rivers.[44]

Iowa was part of a territory known as La Louisiane or Louisiana, and European traders were interested in lead and furs obtained by Indians. The Sauk英语Sauk people and Meskwaki effectively controlled trade on the Mississippi in the late 18th century and early 19th century. Among the early traders on the Mississippi were Julien Dubuque, Robert La Salle, and Paul Marin英语Paul Marin de la Malgue.[44] Along the Missouri River at least five French and English trading houses were built before 1808.[47] In 1800, Napoleon Bonaparte took control of Louisiana from Spain in a treaty.

After the 1803 Louisiana Purchase, Congress divided the Louisiana Purchase into two parts—the Territory of Orleans and the District of Louisiana, with present-day Iowa falling in the latter. The Indiana Territory was created in 1800 to exercise jurisdiction over this portion of the District; William Henry Harrison was its first governor. Much of Iowa was mapped by Zebulon Pike英语Zebulon Pike in 1805,[48] but it was not until the construction of Fort Madison in 1808 that the U.S. established tenuous military control over the region.[49]

 
Plan of Fort Madison, 1810

War of 1812 and unstable U.S. control

编辑

Fort Madison was built to control trade and establish U.S. dominance over the Upper Mississippi, but it was poorly designed and disliked by the Sauk and Ho-Chunk英语Ho-Chunk, many of whom allied with the British, who had not abandoned claims to the territory.[49][50] Fort Madison was defeated by British-supported Indians in 1813 during the War of 1812, and Fort Shelby英语Fort Shelby (Wisconsin) in Prairie du Chien, Wisconsin英语Prairie du Chien, Wisconsin, also fell to the British. Black Hawk英语Black Hawk (chief) took part in the siege of Fort Madison.[51][52]

After the war, the U.S. re-established control of the region through the construction of Fort Armstrong英语Fort Armstrong, Illinois, Fort Snelling英语Fort Snelling in Minnesota, and Fort Atkinson英语Fort Atkinson (Nebraska) in Nebraska.[53]

Trade and Indian removal, 1814–1832

编辑
 
A map of Iowa Indian Territory Accessions

The U.S. encouraged settlement of the east side of the Mississippi and removal of Indians to the west. Trade continued in furs and lead, but disease and forced population movement decimated Indian cultures and economies. A disputed 1804 treaty between Quashquame英语Quashquame and William Henry Harrison that surrendered much of Illinois to the U.S. enraged many Sauk and led to the 1832 Black Hawk War. As punishment for the uprising, and as part of a larger settlement strategy, treaties were subsequently designed to remove all Indians from Iowa.

The Sauk and Meskwaki were pushed out of the Mississippi valley in 1832, out of the Iowa River英语Iowa River valley in 1843, and out of Iowa altogether in 1846. Many Meskwaki later returned to Iowa and settled near Tama, Iowa; the Meskwaki Settlement英语Meskwaki Settlement remains to this day. In 1856 the Iowa Legislature passed an unprecedented act allowing the Meskawki to purchase the land; Indians were not usually permitted to do so. The Ho-Chunk英语Ho-Chunk were removed from Iowa in 1850, and the Dakota were removed by the late 1850s. Western Iowa around modern Council Bluffs was used as a way station for other tribes being moved west, including the Potawatomi英语Potawatomi.

U.S. settlement and statehood, 1832–1860

编辑
 
Iowa Territorial Seal英语Seal of Iowa#Iowa territorial seal

The first American settlers officially moved to Iowa in June 1833.[54] Primarily, they were families from Ohio, Pennsylvania, New York, Indiana, Kentucky, and Virginia.[54] On July 4, 1838, the U.S. Congress established the Territory of Iowa. President Martin Van Buren appointed Robert Lucas英语Robert Lucas (governor) governor of the territory, which at the time had 22 counties and a population of 23,242.[55]

Almost immediately after achieving territorial status, a clamor arose for statehood. On December 28, 1846, Iowa became the 29th state in the Union when President James K. Polk signed Iowa's admission bill into law. Once admitted to the Union, the state's boundary issues resolved, and most of its land purchased from the Indians, Iowa set its direction to development and organized campaigns for settlers and investors, boasting the young frontier state's rich farmlands, fine citizens, free and open society, and good government.[56]

Iowa has a long tradition of state and county fairs. The first and second Iowa State Fair英语Iowa State Fairs were held in the more developed eastern part of the state at Fairfield. The first fair was held October 25–27, 1854, at a cost of around $323. Thereafter, the fair moved to locations closer to the center of the state and in 1886 found a permanent home in Des Moines. The State Fair has been held every year since except for the year 1898 due to the Spanish–American War and the World's Fair being held in nearby Omaha, Nebraska. The fair was also a World War II wartime casualty from 1942–1945, as the fairgrounds were being used as an army supply depot.[57]

Civil War, 1861–1865

编辑
 
Jane and Samuel Kirkwood英语Samuel J. Kirkwood, 1852

Iowa supported the Union during the Civil War, voting heavily for Abraham Lincoln, though there was a strong antiwar "Copperhead英语Copperheads (politics)" movement among settlers of southern origins and among Catholics.[来源请求] There were no battles in the state, although the battle of Athens, Missouri英语Athens, Missouri, 1861, was fought just across the Des Moines River from Croton, Iowa英语Croton, Iowa, and shots from the battle landed in Iowa. Iowa sent large supplies of food to the armies and the eastern cities.[58]

Much of Iowa's support for the Union can be attributed to Samuel J. Kirkwood英语Samuel J. Kirkwood, its first wartime governor. Of a total population of 675,000, about 116,000 men were subjected to military duty. Iowa contributed proportionately more men to Civil War military service than did any other state, north or south, sending more than 75,000 volunteers to the armed forces, over one-sixth of whom were killed before the Confederates surrendered at Appomattox英语Battle of Appomattox Courthouse.[58]

Most fought in the great campaigns in the Mississippi Valley and in the South.[59] Iowa troops fought at Wilson's Creek in Missouri, Pea Ridge in Arkansas, Forts Henry and Donelson, Shiloh, Chattanooga, Chickamauga, Missionary Ridge, and Rossville Gap as well as Vicksburg, Iuka, and Corinth. They served with the Army of the Potomac in Virginia and fought under Union General Philip Sheridan in the Shenandoah Valley. Many died and were buried at Andersonville. They marched on General Nathaniel Banks英语Nathaniel Banks' ill-starred expedition to the Red River. Twenty-seven Iowans英语Iowans have been awarded the Medal of Honor, the highest military decoration awarded by the United States government, which was first awarded in the Civil War.[60]

Iowa had several brigadier generals and four major generals—Grenville Mellen Dodge英语Grenville Mellen Dodge, Samuel R. Curtis英语Samuel R. Curtis, Francis J. Herron英语Francis J. Herron, and Frederick Steele英语Frederick Steele—and saw many of its generals go on to state and national prominence following the war.[58]

Agricultural expansion, 1865–1930

编辑
 
Iowa farm, 1875

Following the Civil War, Iowa's population continued to grow dramatically, from 674,913 people in 1860 to 1,624,615 in 1880. The introduction of railroads in the 1859s and 1860s transformed Iowa into a major agricultural producer.

In 1917, the United States entered World War I and farmers as well as all Iowans experienced a wartime economy. For farmers, the change was significant. Since the beginning of the war in 1914, Iowa farmers had experienced economic prosperity. In the economic sector, Iowa also has undergone considerable change. Beginning with the first farm-related industries developed in the 1870s, Iowa has experienced a gradual increase in the number of business and manufacturing operations.

Depression, World War II, and the rise of manufacturing, 1930–1985

编辑

The transition from an agricultural economy to a mixed economy happened slowly. The Great Depression and World War II accelerated the shift away from smallholder farming to larger farms, and began a trend of urbanization. The period since World War II has witnessed a particular increase in manufacturing operations. While agriculture continued to be the state's dominant industry, Iowans also produce a wide variety of products including refrigerators, washing machines, fountain pens, farm implements, and food products.

The Farm Crisis of the 1980s caused a major recession in Iowa, causing poverty not seen since the Depression.[61] The crisis spurred a major, decade-long population decline.[62]

Reemergence as a mixed economy, 1985–present

编辑

After bottoming out in the 1980s, Iowa's economy began to become increasingly less dependent on agriculture, and by the early 21st century was characterized by a mix of manufacturing, biotechnology, finance and insurance services, and government services.[63] The population of Iowa has increased at a faster rate than the U.S. as a whole,[62] and Iowa now has a predominantly urban population.[64] The Iowa Economic Development Authority, created in 2011 has replaced the Iowa Department of Economic Development and its annual reports are a source of economic information.[65]

2018 estimate[67]

The United States Census Bureau estimates the population of Iowa was 3,156,145 on July 1, 2018, a 3.60% increase since the 2010 Census.[67]

Of the residents of Iowa, 72.2% were born in Iowa, 23.2% were born in a different US state, 0.5% were born in Puerto Rico, U.S. Island areas, or born abroad to American parent(s), and 4.1% were foreign born.[68]

Immigration英语Immigration to the United States from outside the United States resulted in a net increase of 29,386 people, while migration within the country produced a net loss of 41,140 people. 6.5% of Iowa's population were reported as under the age of five, 22.6% under 18, and 14.7% were 65 or older. Males made up approximately 49.6% of the population.[69] Iowa has banned sanctuary cities英语Sanctuary city.[70] The population density of the state is 52.7 people per square mile.[71] The center of population of Iowa is in Marshall County, in the city of Marshalltown.[69]

As of the 2010 Census, the population of Iowa was 3,046,355. The gender makeup of the state was 49.5% male and 50.5% female. 23.9% of the population were under the age of 18; 61.2% were between the ages of 18 and 64; and 14.9% were 65 years of age or older.[72]

Percent population changes by counties in Iowa, 2000–2009. Dark green counties have gains of more than 5%.[78]

Iowa's population is more urban than rural, with 61 percent living in urban areas in 2000, a trend that began in the early 20th century.[64] Urban counties in Iowa grew 8.5% from 2000 to 2008, while rural counties declined by 4.2%.[79] The shift from rural to urban has caused population increases in more urbanized counties such as Dallas, Johnson, Linn, Polk, and Scott, at the expense of more rural counties.[80]

Iowa, in common with other Midwestern states (especially Kansas, Nebraska, North Dakota, and South Dakota), is feeling the brunt of rural flight, although Iowa has been gaining population since approximately 1990. Some smaller communities, such as Denison and Storm Lake, have mitigated this population loss through gains in immigrant laborers.[81]

Another demographic problem for Iowa is the brain drain, in which educated young adults leave the state in search of better prospects in higher education or employment. During the 1990s, Iowa had the second highest exodus rate for single, educated young adults, second only to North Dakota.[82] Significant loss of educated young people contributes to economic stagnation and the loss of services for remaining citizens.

A 2001 survey from the City University of New York found 52% of Iowans are Protestant, while 23% are Catholic, and other religions made up 6%. 13% responded with non-religious, and 5% did not answer.[92] A survey from the Association of Religion Data Archives英语Association of Religion Data Archives (ARDA) in 2010 found that the largest Protestant denominations were the United Methodist Church with 235,190 adherents and the Evangelical Lutheran Church in America with 229,557. The largest non Protestant religion was Catholicism with 503,080 adherents. The state has a great number of Reformed denominations. The Presbyterian Church (USA) had almost 290 congregations and 51,380 members followed by the Reformed Church in America with 80 churches and 40,000 members, and the United Church of Christ had 180 churches and 39,000 members.[93]

The study Religious Congregations & Membership: 2000[94] found in the southernmost two tiers of Iowa counties and in other counties in the center of the state, the largest religious group was the United Methodist Church; in the northeast part of the state, including Dubuque and Linn counties (where Cedar Rapids is located), the Catholic Church was the largest; and in ten counties, including three in the northern tier, the Evangelical Lutheran Church in America was the largest. The study also found rapid growth in Evangelical Christian denominations. Dubuque is home to the Archdiocese of Dubuque, which serves as the ecclesiastical province for all 3 other dioceses in the state and for all the Catholics in the entire state of Iowa.

Historically, religious sects and orders who desired to live apart from the rest of society established themselves in Iowa, such as the Amish and Mennonite near Kalona and in other parts of eastern Iowa such as Davis County and Buchanan County.[95] Other religious sects and orders living apart include Quakers around West Branch and Le Grand, German Pietists who founded the Amana Colonies英语Amana Colonies, followers of Transcendental Meditation英语Transcendental Meditation who founded Maharishi Vedic City, and Order of Cistercians of the Strict Observance monks and nuns at the New Melleray英语New Melleray Abbey and Our Lady of the Mississippi英语Our Lady of the Mississippi Abbey Abbies near Dubuque.

The Babel Proclamation英语Babel Proclamation of 1918 banned the speaking of German in public. Around Pella, residents of Dutch descent once spoke the Pella Dutch dialect英语Pella Dutch dialect.

No other language is spoken by more than 0.5 percent of the Iowa population.[97] The only indigenous language used regularly in Iowa is Meskwaki英语Fox language, used around the Meskwaki Settlement英语Meskwaki Settlement.[103]

Iowa gross state products by industry, 2006[109]

While Iowa is often viewed as a farming state, agriculture is a relatively small portion of the state's diversified economy, with manufacturing, biotechnology, finance and insurance services, and government services contributing substantially to Iowa's economy.[63] This economic diversity has helped Iowa weather the late 2000s recession better than most states, with unemployment substantially lower than the rest of the nation.[110][111]

If the economy is measured by gross domestic product, in 2005 Iowa's GDP was about US$124 billion.[112] If measured by gross state product, for 2005 it was US$113.5 billion.[113] Its per capita income for 2006 was US$23,340.[113]

On July 2, 2009, Standard & Poor's rated the state of Iowa's credit as AAA (the highest of its credit ratings, held by only 11 U.S. state governments).[114]

As of December 2015, the state's unemployment rate is 3.4%.[115]

Manufacturing

编辑

Manufacturing is the largest sector of Iowa's economy, with $20.8 billion (21%) of Iowa's 2003 gross state product. Major manufacturing sectors include food processing, heavy machinery, and agricultural chemicals. Sixteen percent of Iowa's workforce is dedicated to manufacturing.[63]

Food processing is the largest component of manufacturing. Besides processed food, industrial outputs include machinery, electric equipment, chemical products, publishing, and primary metals. Companies with direct or indirect processing facilities in Iowa include ConAgra Foods, Wells Blue Bunny英语Wells Dairy, Barilla英语Barilla Group, Heinz, Tone's Spices, General Mills, and Quaker Oats.

Though industrial-scale, commodity agriculture predominates in much of the state, Iowa has seen growth in the organic farming sector. Iowa ranks fifth in the nation in total number of organic farms. In 2016, there were approximately 732 organic farms in the state, an increase of about 5% from the previous year, and 103,136 organic acres, an increase of 9,429 from the previous year.[117][118] Iowa has also seen an increase in demand for local, sustainably-grown food.

As of 2007, the direct production and sale of conventional agricultural commodities contributed only about 3.5% of Iowa's gross state product.[124] In 2002 the impact of the indirect role of agriculture in Iowa's economy, including agriculture-affiliated business, was calculated at 16.4% in terms of value added and 24.3% in terms of total output. This was lower than the economic impact of non-farm manufacturing, which accounted for 22.4% of total value added and 26.5% of total output.[125] Iowa's main conventional agricultural commodities are hogs, corn, soybeans, oats, cattle, eggs, and dairy products. Iowa is the nation's largest producer of ethanol and corn and some years is the largest grower of soybeans. In 2008, the 92,600 farms in Iowa produced 19% of the nation's corn, 17% of the soybeans, 30% of the hogs, and 14% of the eggs.[126]

On December 14, 2015, Branstad became the longest serving governor in U.S. history, serving (at that time) 20 years, 11 months, and 3 days; eclipsing George Clinton, who served 21 years until 1804.[157] Lieutenant Governor Kim Reynolds succeeded him on May 24, 2017, following Branstad's appointment as U.S. Ambassador to China.

As of February 1, 2016, there were 2,095,639 registered voters. 635,687 or 30.3% were Democrats, 800,629 or 38.2% of voters were not registered in a party, 651,039 or 31.1% were Republicans, and 8,284 or 0.004% were registered with another party.[158]

Presidential caucus

编辑

The state gets considerable attention every four years because the Iowa caucus英语Iowa caucus, gatherings of voters to select delegates to the state conventions, is the first presidential caucus in the country. The caucuses, held in January or February of the election year, involve people gathering in homes or public places and choosing their candidates, rather than casting secret ballots as is done in a presidential primary election.[来源请求] Along with the New Hampshire primary英语New Hampshire primary the following week, Iowa's caucuses have become the starting points for choosing the two major-party candidates for president.[159] The national and international media give Iowa and New Hampshire extensive attention, which gives Iowa voters leverage.[160] Those who enter the caucus race often expend enormous effort to reach voters in each of Iowa's 99 counties.[来源请求]

Civil rights

Racial equality

In the 19th century Iowa was among the earliest states to enact prohibitions against race discrimination, especially in education, but was slow to achieve full integration in the 20th century. In the very first decision of the Supreme Court of Iowa英语Supreme Court of IowaIn Re the Matter of Ralph,[161] decided July 1839–the Court rejected slavery in a decision that found a slave named Ralph became free when he stepped on Iowa soil, 26 years before the end of the Civil War.[162] The state did away with racial barriers to marriage in 1851, more than 100 years before the U.S. Supreme Court would ban miscegenation statutes nationwide.[163]

The Iowa Supreme Court decided Clark v. The Board of Directors[164] in 1868, ruling that racially segregated "separate but equal" schools had no place in Iowa, 85 years before Brown v. Board of Education.[162] By 1875, a number of additional court rulings effectively ended segregation in Iowa schools.[165] Social and housing discrimination continued against Blacks at state universities until the 1950s.[166] The Court heard Coger v. The North Western Union Packet Co.[167] in 1873, ruling against racial discrimination in public accommodations 91 years before the U.S. Supreme Court reached the same decision.[162]

In 1884, the Iowa Civil Rights Act apparently outlawed discrimination by businesses, reading: "All persons within this state shall be entitled to the full and equal enjoyment of the accommodations, advantages, facilities, and privileges of inns, restaurants, chophouses, eating houses, lunch counters, and all other places where refreshments are served, public conveyances, barber shops, bathhouses, theaters, and all other places of amusement." However, the courts chose to narrowly apply this act, allowing de facto discrimination to continue.[168] Racial discrimination at public businesses was not deemed illegal until 1949, when the court ruled in State of Iowa v. Katz英语State of Iowa v. Katz that businesses had to serve customers regardless of race; the case began when Edna Griffin英语Edna Griffin was denied service at a Des Moines drugstore.[169] Full racial civil rights were codified under the Iowa Civil Rights Act of 1965.[170]

Women's rights

编辑

As with racial equality, Iowa was a vanguard in women's rights in the mid-19th century, but was slow to give women the right to vote. In 1847, the University of Iowa became the first public university in the U.S. to admit men and women on an equal basis.[171] In 1869, Iowa became the first state in the union to admit women to the practice of law, with the Court ruling women may not be denied the right to practice law in Iowa and admitting Arabella A. Mansfield英语Arabella A. Mansfield to the practice of law.[162] Several attempts to grant full voting rights to Iowa women were defeated between 1870 and 1919. In 1894 women were given "partial suffrage", which allowed them to vote on issues, but not for candidates. It was not until the Nineteenth Amendment to the United States Constitution was ratified in 1920 that women had full suffrage in Iowa.[172] Although Iowa supported the Federal Equal Rights Amendment, in 1980 and 1992 Iowa voters rejected an Equal Rights Amendment to the state constitution.[173] Iowa did add the word "women" to the Iowa Constitution in 1998. After Amendment, it reads: "All men and women are, by nature, free and equal, and have certain inalienable rights – among which are those of enjoying and defending life and liberty, acquiring, possessing and protecting property, and pursuing and obtaining safety and happiness." [174]

In May 2018 Iowa signed into law one of the country's most restrictive abortion bans: the requirement that a doctor cannot perform an abortion if they can detect a fetal heartbeat, which in many cases would restrict abortions pregnancies less than six weeks old, a period of time many women do not even know they are pregnant. In January 2019 an Iowa state judge struck down the so-called "fetal heartbeat" law, saying it was unconstitutional.[175]

Political speech

编辑

In the aftermath of the civil rights movement, court decisions in Iowa clarified and expanded citizens' rights. The landmark U.S. Supreme Court case Tinker v. Des Moines Independent Community School District英语Tinker v. Des Moines Independent Community School District (1969) confirmed the right of students to express political views. The state's law criminalizing same-sex sexual activity was repealed in June 1976, 27 years before Lawrence v. Texas.

LGBT rights

编辑

In 2007, the Iowa Legislature added "sexual orientation" and "gender identity" to the protected classes listed in the Iowa Civil Rights Act.[176]

On April 3, 2009, the Iowa Supreme Court decided Varnum v. Brien英语Varnum v. Brien,[177] holding in a unanimous decision,[178] the state's law forbidding same-sex marriage was unconstitutional英语unconstitutional. This made Iowa the third state in the U.S. and first in the Midwest to permit same-sex marriage.[179] [180]

Sister jurisdictions

Iowa has ten official partner jurisdictions:[181]

Education

编辑

Primary and secondary schools

编辑

Iowa is often credited with the start of the high school movement in the U.S. Around 1910, secondary schools as we know them today were established across the state, which was unprecedented at the time. As the high school movement gathered pace and went beyond Iowa, there was clear evidence of how more time spent in school led to greater income.[来源请求]

The four-year graduation rate for high schoolers was 90% in 2015.[182] The state has the top graduation rate in the nation.[183] Iowa has 365 school districts,[184] and has the 12th lowest student-to-teacher ratio of 13.8.[185] Teacher pay is ranked 42nd, with the average salary being $39,284.[185]

The Iowa State Board of Education works with the Iowa Department of Education to provide oversight, supervision, and support for the state's education system that includes all public elementary and secondary schools, nonpublic schools that receive state accreditation, area education agencies, community colleges, and teacher preparation programs. The State Board consists of ten members: nine voting members who are appointed by the governor for six-year terms and subject to Senate confirmation; and one nonvoting student member who serves a one-year term, also appointed by the governor. The Iowa Board of Educational Examiners is an autonomous board in control of teacher licensure standards and professional discipline; it has a majority of licensed teachers as members and is the oldest state educational board.[来源请求]

截至2015年 (2015-Missing required parameter 1=month!) transportation spending is a significant part of the budgets of rural school districts as many are geographically large and must transport students across vast distances. This reduces the amount of money spent on other aspects of the districts.[186]
