Economic share is the percentage of the state's economy that is accounted for by an individual county. The economic share is measured as the average of the percentage of the state's employment, population and personal income that occurs in a particular county. The table below presents those counties that account for a large proportion of the state's economy, based on employment, population and income.
Missouri's metropolitan areas account for a large part of the state's economy with St. Louis (20.5%) and Jackson counties (11.6%) together tallying nearly one-third of the total. Conversely, several counties in the state account for less than 0.1% of the state's economy each.
From 1995 to 2005, county contribution to the state's economy has not changed drastically. However, there have been some shifts in Missouri's economic composition. The map below shows the change in county share from 1995 to 2005. Counties in green gained economic share over the period, while counties in orange had decreasing shares.
The most notable shift is found in the St. Louis and Kansas City areas as St. Louis County, St. Louis City and Jackson County decreased in share while surrounding counties generally increased, particularly St. Charles County. This is indicative of sprawl in Missouri's major metropolitan areas, as economic activity tends to spread outside of the urban core.
