Clark County’s population grew to 461,010 this year and continues to grow, primarily because people are moving here.

That may be a no-brainer to anybody clued into the tight local housing market, but population estimates released Thursday by the state Office of Financial Management show just how substantial migration to the area is.

While the county population grew by about 10,000 people between 2015 and 2016, almost 7,000 of them were newcomers. That’s the biggest gain in newcomers since 2005-2006.

Keep in mind that people moved away from Clark County between 2009 and 2010. And, from 2010 to 2011, the county gained just 189 newcomers.

“Back then, people were trapped because of the housing market. A lot of people couldn’t sell their houses and couldn’t move,” said Yi Zhao, Washington’s chief demographer. “Migration was low nationwide.”
