Each state’s population determines the number of representatives that it will be allocated in the House of Representatives.
Every 10 years, after the Census Bureau tallies the population, some states gain seats, others lose them, to reflect faster population growth in some states than in others. This process of reallocating seats is called reapportionment.
The Losers:
New York and Ohio each lost two seats. Illinois, New Jersey, Michigan, Missouri, Pennsylvania, Louisiana, Massachusetts and Iowa each lost one seat.
The Winners:
Texas, Arizona, Nevada, Utah, South Carolina, Florida, Georgia and Washington.
Texas gained four seats, Florida gained two, and the others each gained one.
