About the Census

Every 10 years, the United States conducts a census of the entire population.

The census is used to determine Congressional representation and allocate billions of dollars in federal funding which supports schools, hospitals, infrastructure developments and other community-based services.

Local government, foundations, businesses, educators and others, rely on census information to make important decisions about local policies, funding distribution, where to start businesses and more. The participation of every resident in the census will help make sure that our region receives the federal funds that it needs to serve everyone equitably. It’s why our goal is to make sure 100% of our residents are counted.
