Statewide, California appears to be moving toward the middle – at least when it comes to where they call home.

According to Census Bureau figures released today, the state’s population rose 10 percent from April 2000 to April 2010. The Golden State grew from 33.9 million residents to 37.3 million resident during that decade, the census reported. Most of that growth appears to have come in the counties that span the middle of the state.

Riverside County had the biggest jump, increasing 41 percent from 2000 to 2010. The city of Beaumont in that county leaped 224 percent from 11,384 to 36,887 people.

Next was Placer County with a 40 percent jump. The city of Lincoln skyrocketed 282 percent from 11,205 to 42,819 people.

Other counties that grew more than 20 percent included Imperial, Kern, Madera, Merced and Tulare.

The only counties that saw population decreases were three small regions in the Sierra Nevada. They were Alpine County (down 3 percent), Plumas County (down 4 percent) and Sierra County (down 9 percent).
