Greater St. Louis

Greater St. Louis is the 21st-largest metropolitan statistical area (MSA) in the United States, the largest in Missouri, and the second-largest in Illinois. Its core city—St. Louis, Missouri—sits in the geographic center of the metro area, on the west bank of the Mississippi River. The river bisects the metro area geographically between Illinois and Missouri, although the latter portion is much more populous. The MSA includes St. Louis County, which is independent of the City of St. Louis; their two populations are generally tabulated separately.

The St. Louis, MO-IL metropolitan statistical area (MSA) includes the City of St. Louis; the Illinois counties of Bond, Calhoun, Clinton, Jersey, Macoupin, Madison, Monroe, and St. Clair (known collectively as the Metro East); and the Missouri counties of Crawford (only the City of Sullivan), Franklin, Jefferson, Lincoln, St. Charles, St. Louis (separate from and not inclusive of the city of St. Louis), and Warren.

The larger '''St. Louis–St. Charles–Farmington, MO–IL combined statistical area''' (CSA) includes all of the aforementioned MSA, plus the Farmington, MO micropolitan statistical area, which includes St. Francois County, Missouri, and the Centralia, IL micropolitan statistical area, which includes Marion County, Illinois.

In 2020, the St. Louis MSA was the 21st largest in the nation with a population of 2,820,253. The larger CSA is ranked 20th largest in the United States, with a population of 2,909,003. Due to slow growth in the St. Louis area paired with comparatively rapid growth in the Sun Belt, the St. Louis MSA fell out of the top 20 largest MSAs in the United States in 2017 for the first time since 1840.

As of 2021, Greater St. Louis is home to the headquarters of ten of Missouri's eleven Fortune 500 companies, six Fortune 1,000 companies, and two of the top 30 largest private companies in America, as ranked by Forbes. The metropolitan area received the All-America City Award in 2008.

History
The Illini Confederacy at one time dominated the lands where St. Louis is now located. During the 17th century, the population of indigenous peoples in the area was well over tens of thousands, with a population of 20,000 in the Grand Village of Illinois. Indigenous peoples in the area built earthwork mounds on both sides of the Mississippi River, with the Cahokia Mounds being the regional center. Due to mounds inside city limits, St. Louis still has a nickname of "Mound City".

Pierre Laclede Liguest and his 13-year-old grandson, Auguste Chouteau, selected St. Louis as the site for a French fur trading post in 1764 due to its proximity to the Mississippi and Missouri Rivers, as well as its propensity to not flood. In 1770, St. Louis ownership was transferred to Spain, and then returned to France during a secret treaty (Treaty of San Ildefonso), before becoming a part of the United States during the 1803 Louisiana Purchase.

St. Louis steadily grew after the Louisiana Purchase due to the city being the starting point for Lewis and Clark and its access to water transportation. It was incorporated as a city in 1823. Between 1840 and 1860, the population exploded with immigrants, especially those of German and Irish descent. St. Louis's current boundaries were established in 1876. After the American Civil War, St. Louis continued to grow into a major manufacturing center due to its access to rail and water transportation. By the 1890s, St. Louis was the 4th largest city in the United States.

In 1904 St. Louis hosted the world's fair in Forest Park along with the Olympics at Washington University's Francis Field. More than 20 million people visited the city during the fairs seven-month long run. St. Louis was seen as a city of industrialization with ties to the automobile industry. The Great Migration between World War I and World War II brought thousands of African Americans to the city, boosting St. Louis's population to 800,000 by 1940. The population peaked in 1950 at 856,000, however there was no more room for expansion within city boundaries and earlier immigrant generations started moving to suburbs that could not be annexed.

During the mid-1960s the Gateway Arch and Busch Stadium started being built in part to help revitalize the central business district with a 30-year downtown building boom following. Today, there is a continued population decline, however, revitalization efforts are still well under way.
