About the Geography Program

Geography is central to the work of the Census Bureau, providing the framework for survey design, sample selection, data collection, tabulation, and dissemination. Geography provides meaning and context to statistical data.

Use of the latest and best geographic methodologies is critical to the Census Bureau’s ability to serve as the leading provider of statistical and geospatial data. Our geographic area concepts, information, and statistical data must keep pace with the needs of the researchers and analysts who work to understand the changing distribution and characteristics of our people, places, and economy.
