Abstract:

Nathan Keyfitz made important contributions in many areas of mathematics, demography, and statistics. This paper concentrates on two major advances to the practice of survey sampling that Keyfitz made early in his career. One deals with the redesign of a survey in which it is desired to retain as many first stage sampling units as possible from the old design in the new design. This is subject, however, to not changing the probability of selection over all possible samples for any first stage unit. The second advance by Keyfitz was the development of a new method of variance estimation for sample surveys. Keyfitz is the original developer of the linearization method for estimating variances, which is one of the two primary variance estimation methods used today, more than 50 years after Keyfitz's ground-breaking paper.
