According to Article I, Section 2 of the U.S. Constitution, an apportionment of representatives among the states is required every decade based on the state population counts that result from the decennial census.
The United States Census Bureau is releasing that data, along with population totals for the nation and the states, on Monday, April 26.
The U.S. Census Bureau says the nation's population has risen to 331,449,281, a 7.4% increase since 2010. The Midwest has the slowest region in growth, at 3.1%. Wisconsin grew 3.6%.
There are 435 congressional districts within the United States to be allocated. Representative districts are typically divided by units of approximately 710,000 residents, according to GovTrack.us.
"The apportionment population consists of the resident population of the 50 states, plus the overseas military and federal civilian employees and their dependents living with them who could be allocated to a home state," from the census bureau's website.
Currently, Wisconsin has eight representatives that are elected to two-year terms in the House of Representatives.
