Answer:
The Constitutional basis for conducting the decennial census is to reapportion the U.S. House of Representatives. Apportionment is the process of dividing the 435 memberships, or seats, in the U.S. House of Representatives among the 50 states.
Explanation:
It is mandated by Article I, Section 2 of the Constitution and takes place every 10 years. The data collected by the census determine the number of seats each state has in the U.S. House of Representatives (a process called apportionment) and is also used to distribute billions in federal funds to local communities.
