Аннотация:"This paper discusses the problem of modeling demographic variables for the purpose of forecasting." Two empirical model selection procedures, a time series approach and a sequential testing procedure, are applied to suggest final-form forecasting equations for an Australian births series, namely, first nuptial confinements. The models are compared with the method used to construct the Australian government's IMPACT demographic module. Comments by Joseph B. Kadane, Ronald Lee, Roderick J. A. Little, John F. Long, and Kenneth F. Wallis are included, together with a rejoinder by the author.
