Los Angeles MSA: Population 1970-2010
The first chart below shows the three population change factors for three periods adjusted for annual average amounts. Domestic migration (NDM) was consistently negative and B-D accounted for a majority of the population increase.
The second chart shows the same data but with an adjustment to reflect births to immigrants shifted to NIM. In it, net immigration (NIM) accounts for nearly all of the population increase in the first period and all of it in the two most recent periods. This implies that net B-D among the native born population was slightly negative in the most recent period.
