This elementary approach will lead to the introduction of some new formulas that will simplify both the understanding and the calculation of various quantities that are relevant to demography and to the mathematical theory of population...

Published: 01 November 1978
...Dudley L. Poston, Jr.; Ralph White Abstract The ecological theory of migration asserts that change in sustenance organization, to the extent that it produces changes in the opportunities for living, necessitates a change in population size. Migration may thus be viewed as a demographic response...

Published: 01 August 1969
...David D. McFarland Abstract Expositions and elementary proofs are given for the basic theorems of stable population theory: That a population subjected to vital rates (not necessarily constant over time) satisfying certain postulates will eventually “forget” its original age distribution and take...

... Unidos tardó muchos años hata llegar a su presente política, y sería poco realista esperar que la Union Soviética canbie más rapidamente. Summary Marxist theories led Soviet writers to view the population problems of less developed countries in rather simplistic terms: Since overpopulation is caused...

...Robert A. Pollak Abstract The ability of classical stable population theory to determine the equilibrium growth rate and age structure of a population from its vital rates in a single period depends on assuming that the observed maternity rates are equilibrium rates. This paper resolves the two-sex...

Published: 01 February 1982
...Thomas J. Espenshade; Leon F. Bouvier; W. Brian Arthur Abstract This paper reports on work aimed at extending stable population theory to include immigration. Its central finding is that, as long as fertility is below replacement, a constant number and age distribution of immigrants (with fixed...

Second, I suggest a statistical model of household consumption as a function of household size and age structure to quantitatively evaluate the extent of economies of scale in consumption of energy-intensive goods...

...Kenneth W. Wachter Abstract Goldman (1978) has proposed a formula derived from stable population theory for estimating growth rates from certain counts of younger and older sisters in a population. Computer microsimulation outputs show extraordinarily large statistical errors for estimation when...

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...
