The 2010 Census is about to launch its next operation, Address Canvassing. The first phase started March 29; the final phase will conclude by June 19.
The Census Bureau has hired about 140,000 people to canvass all known streets and roads throughout the country, identifying every living quarter where people live or could potentially live, and verifying more than 145 million addresses.
For the first time in Decennial Census history, census workers will confirm, add and delete addresses using a Global Positioning System (GPS)-equipped hand-held computer. Each building or structure will receive GPS coordinates to make sure it is also recorded in the right location.
