BY Paul Solman  March 29, 2011 at 11:36 AM EDT

According to the U.S. Census Bureau the nation grew almost ten percent over the last decade — from 281.4 million in 2000 to 308.7 million in 2010. The country’s racial mix has shifted too. The number of people that identify as Hispanic or Latino has grown 43 percent since 2000.

To view data on your state’s population and racial makeup and how they’ve changed in the last decade, mouse over the Census map below.

Of course, a key reason for collecting Census data: legislative apportionment. The number of seats a state gets in the House of Representatives is based on its population: the larger the state, the more the seats. Has your state lost or gained seats? Roll over the “apportionment” map to find out how many since 1910.

And if you’re interested in population density or population change by state, just click on the appropriate tab.

Nevada was the fastest growing state in the last decade, swelling by 35 percent, which would explain the infamous housing boom there. On the other end of the spectrum, Michigan lost 0.6 percent of its population between 2000 and 2010. As Dante Chinni reported last week, the city of Detroit alone shrank by 25 percent. See our recent Detroit photo essay for some of the visual evidence.
