Published: 01 February 1981
...Hania Zlotnik; Kenneth Hill Abstract The indirect methods of demographic estimation available to date are often inadequate to estimate levels in the presence of trends. The use of measures relative to hypothetical cohorts to minimize the effectsoftrends and estimate period levels is described...

We present computational methods which employ these estimates of morbid state transitions to produce life table functions for...

Panel C gives the age-specific acceptor method mix. The T or hypothetical method is not included in the so-called standard (8) method mix, which, al- though...

... higher-order birth and union events by woman’s birth cohort and country. The estimated parameters are used to generate country- and cohort-specific populations of women with stochastically predicted family life courses. We use the hypothetical populations to decompose changes in the percentage of mothers...

... indices of measurement within cohorts of students, as these will be used for projection purposes. Of course, period indices can be useful but they are quite crude to evaluate educa- tional attainments, unless we derive measures for hypothetical cohorts. One such crude index is the school en- rolment ratio...

... encapsulating the lifetime experience of a real (or hypothetical) cohort of persons (cf. Key tz 1977; Siegel and Swanson 2004). In multistate (or increment-decrement) contexts, in which individuals can move be- tween different living states, the situation is more complex. To determine population size and state...

... the broad contours of historical changes in the demography of grandparenthood in the United States for the 1880–1960 birth cohorts. Then we examine race and sex differences in grandparenthood in the past and present, which reveal declining inequality in the demography of grandparenthood and a...

... reproductive histories that have been collected in such surveys provide a largely unexploited source of data for the analysis of trends in timing. An analysis by birth cohort of the fertility experience of 592 ever-married women surveyed in San Juan, Puerto Rico, in 1966 shows that significant changes in...

...Karl E. Taeuber Summary Most migration analyses focus on net migration and are concerned with areal redistributions of population. Migration may also be studied as an event in the life-cycle of an individual, and migration rates may be defined as properties of cohorts. A number of efforts to...

... concerned with decomposing the sources of these changes. Thus, when graphing cohort-based variation in black and white men’s and women’s mortality rates, we chose values of age and period that were close to their respective means. The choice of these values was not to exacerbate or minimize hypothetical...

Population projections for ten states are made, using identical data and cohort component techniques, except for the different formulations of migration rates. Differences among the three sets of projections are noted, and conclusions are...
