Figure This!

The United States conducted its first census in 1790. Marshals of US judicial districts visited every home, asking for the name of the head of the family and the number of persons in each household. The reported population was 3.9 million.

In the late 1990s, the fastest-growing states were concentrated in the South and West.

By order of the US Constitution, a census must be conducted every 10 years. This has traditionally been done in the years ending in 0.

Every two years, the Census Bureau conducts a sampling focused on a particular area, such as transportation or housing, to identify trends.

The results of the US Census determine each state’s number of members in the House of Representatives.
