Our comparison of residence and preferences yields the same con- clusion in both 1972 and 1988-if everyone were to live in the location that he or she preferred, the distribution of population would be different than current residence...

Two hypotheses are formulated governing the relationship of the closed and open birth intervals with the fecundability distribution of fertile women, and Parity Progression Ratios which are largely influenced by the proportion of women becoming sterile after each parity. The data...

Afterwards, we set up a system of equations leading to the distribution of the entrants in the cohort according to the levels of their educational attainment, a system of equations for which a simple solution will depend on two assumptions...

The positive factors comprise (1) a term proportional to the population size, p , for that particular year, and (2) a term equal...

... of the two exponents (m, or m2) of the type I distribution. It has been shown that the proportions of women married in the age groups 20-24 years and 25-29 years can be used for approximate evaluations of both of these parameters. While estimates of a, and m, are sufficient to generate a relative...

This leads to a pair of easily implemented formulas for upperand lower-bound estimates of the expected proportion of the population ever controlling and the distribution of controllers by parity. The power of CPA is illustrated, using census data for currently married couples...

In particular, the small number of tracts in the middle of the distribution suggests a complex process of change...

In this paper we estimate the parameters of the assumed distributions of these three events using a minimum distance estimation model and data from the 1970 Brazilian census. The parameter estimates are shown to be similar to those obtained...
