There are two -- yes, two -- town halls in Southern California this weekend to discuss the idea of a constitutional convention. (Full disclosure: New America is a sponsor of one of them). The first is tonight--Friday night--in Santa Monica. Details are here. The second is Saturday at USC. Details here.

Here's a link to a new report from USC researchers on the demographics of California. The headline is that California's population is becoming more settled and homegrown. Today, more than 70 percent of Californians ages 15 to 24 were born and raised here. In 1990, barely half of that group -- 53 percent -- were born and raised here.

The report's authors, including Dowell Myers, write that such figures suggest a new narrative for the stat -- the "surprising transformation" of California from a "migration magnet" to a "more self-contained society that depends on its present members." This new narrative suggests a different approach in policy -- the new generation of homegrown Californians wants greater public services and is willing pay more in taxes.

We need more of a debate about this transformation. As a Californian, I'm not sure a more stable, homegrown state population is a welcome development. What makes California special is that it's always been a destination for people from around the world and around the country -- America's America. Do we want to adapt this transformation that the USC study outlines, or should we attempt to reverse it?
