Alaska native fertility trends, 1950-1978.

Fertility rates for Alaska Natives based on officially registered births have shown considerable change since 1950, reflecting the increasing incorporation of this group into the dominant American culture. Their fertility experience has in many regards been similar to that of developing countries during the process of modernization. A gradual rise in fertility prior to 1962 was most likely the result of increased fecundity due to declining breast feeding. The rapid decline after that time is seen as a response to increasing incentives for fertility control. The decline was facilitated by the beginning of family planning programs in 1965.
