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.

Activity is already starting in the preparation of Census 2020 and this page will be a source of information for Delaware County.
The County will be conducting the Local Update of Certified Addresses (LUCA) for all communities except Dublin, Columbus, and Westerville, which are performing their own review. If we feel that portions of the address update need to be checked by individual communities, particularly in municipalities, we will be contacting you individually.

Delaware County will be creating a Complete Count Committee to get the word out on how important it is to have a complete record of our population. Resources will be regularly updated below.
