The California Department of Finance released its annual county population report today, revealing a modest statewide growth of 1.17 percent, or 438,000 people, from July 1, 2006 to July 1, 2007. The rate has remained relatively consistent during the past several years.
The figure represents the natural increase, or births minus deaths, as well as those who have moved into California from other countries or elsewhere in the nation.
Two-thirds of the state’s growth, or 327,000 people, was from natural increase. Net migration accounted for the remaining 25 percent or 111,000 people. This includes foreign immigrants and migrants from other states.
In Contra Costa and Alameda counties, the growth rates of 1.11 and 1.28 percent respectively rose slightly over the prior year.
Contra Costa gained 13,189 new residents with about half the result of natural increase. The county had a net immigration of 4,168 people and a net domestic migration increase of 2,273 new residents.
Alameda County saw 16,761 new residents with 68 percent, or 11,522 people, the result of natural increase. Unlike Contra Costa County, Alameda actually lost 4,794 residents to the rest of the nation but posted an increase of 10,033 new immigrants for a net migration of 5,239 people.
