Journal Article
Demography (1970) 7 (1): 93–120.
Published: 01 February 1970
...Ansley J. Coale Abstract A fundamental theorem of mathematical demography states that two closed populations sharing the same extended history of net fertility, no matter how variable, have the same age composition. In consequence, when in any population net fertility has long followed a purely...

The method is derived from stable population theory and it furnishes good estimates insofar as the current crude vital rates of a population are close to its intrinsic...

Their models, however, assume a “closedpopulation which is subject only to the processes of fertility...

However, analysis of official statistics indicates that immigrants who arrived since World War II now comprise a substantial...

It uses it also to obtain expressions for the transient response of the age...

Numerical examples using both hypothetical and actual populations demonstrate that for declines of any length, the product of the two factors yields momentum values that closely agree with the results of population projections.

On the other hand, at ages 95 and over—especially for centenarians—the enumerated populations significantly exceed the projected ones...

Mortality is lower in urban areas than in rural areas, whereas total fertility is approximately the same in both. Our estimates of fertility and mortality imply stable populations which match closely the observed age...
