Abstract
FOLLOWING up two previous studies of recent changes in the population of New York State, W. A. Anderson now examines the natural increase in that population (Cornell Univ. Agricultural Experiment Station, Bull. 733, 1940). ‘Natural increase’ is here measured through an index in which the number of children less than five years of age per 1,000 women aged 20–44 years is divided by a replacement ratio, this ratio being the number of children less than five years of age per 1,000 women, aged 20–44, in the stationary population which would result from the continual operation of the current mortality-rates and in the absence of any migration.
