Reply to “On ‘a new look at entropy and the life table’” by S. Mitra
Derivations by Mitre were made on the approximation of H in quantifying the alteration in life expectancy due to sudden mortality change as employed by Keyfitz in short note on the Taeuber paradox. The author replies to these formulations and takes new look at entropy and the life table and discusses some implications. The example is given that Mitre set up values for H which exceeded unity in the Coale and Demeny West Life Tables; this was done …
A new look at entropy and the life table
The mathematical derivations described in this paper offer a new look at the entropy of the life table, denoted by H. Contrary to previous claims, it is theoretically possible, and has been observed empirically, for life tables to have entropy values greater than unity. A re-expression of H as a weighted average of life expectancy at different ages relative to life expectancy at birth demonstrates clearly the conditions under which reductions in …
Calculation of life tables from survey data
Life table calculations from survey data are frequently based on events for which exact dates are not available. When these dates are coded in monthly form (e.g., century months), estimates should take into account the fact that the first duration interval—the interval which captures events occurring in the first month of exposure—is half the length of all remaining intervals. Although failure to do so has a trivial effect on many demographic cal…
Sex differences in life cycle measures of widowhood
Using formulas which measure life cycle characteristics of widowhood as a function of life table survivorship and age at marriage, we illustrate changes in patterns of widowhood and widowerhood since 1950, as well as differences by race, by age of bride and of groom, and by age differences between spouses. Although the current inequality in the risks of widowhood and widowerhood for the average couple is mostly due to sex differences in mortality…
