The United States Constitution requires that every 10 years a Census shall be conducted to apportion the United States House of Representatives. The first Census began on August 2, 1790 when the total United States population was 3,919,214 people.

Delaware County has experienced tremendous growth since the last 2010 Census. This map shows a red dot for every building permit since the beginning of 2010. Throughout the United States, every address will receive a Census form by April 1, 2020. Information collected during the Census helps determine the number of seats each state has in the U.S. House of Representatives. Responding to the Census also helps communities get the funding they need and helps businesses make decisions that grow the economy.

Census information impacts the daily lives of residents, informing important decisions about funding for services and facilities in the community, including health care, senior centers, jobs, roads, schools and businesses. More than $675 billion in federal funding flows back to states and local communities each year based on census data.

Responses to the Census are secure and protected by federal law. Your answers can only be used to produce statistics—they cannot be used against you in any way. By law, all household and business survey responses to the U.S. Census Bureau are kept completely confidential.

Online Responses Accepted for the 2020 Census

New in 2020, each home will receive a postcard invitation to respond to a short questionnaire — by phone, mail or online.

Once the invitation arrives, you should respond for your home in one of three ways: online, by phone or by mail. Additional information can be found below or on the Census 2020 website.
