Census results help determine how billions of dollars in federal funding flow into states and communities each year. The results determine how many seats in Congress each state gets.
It's mandated by the U.S. Constitution in Article 1, Section 2: The U.S. has counted its population every 10 years since 1790.
The U.S. Constitution mandates that the country count its population once every 10 years. The results are used to adjust or redraw electoral districts, based on where populations have increased or decreased.
State legislatures or independent bipartisan commissions are responsible for redrawing congressional districts. The U.S. Census Bureau provides states with population for this purpose.
