Welcome to the Missouri Census Data Center
The Missouri Census Data Center (MCDC) is a cooperative program among state agencies in Missouri and the U.S. Bureau of the Census. Its purpose is to enhance awareness of and access to public data, especially Census Bureau products.
The MCDC data archive, which includes many national collections as well as Missouri-specific data, is one of the premier sites in the country for accessing census and other public, machine-readable demographic and geographic data. Data may be accessed directly, via the public machine readable data archive, or by using one of the custom applications.
Email us directly for questions about census data or any of MCDC's data or applications.
