A log-linear approach to disaggregated micro-level population forecasts.

"This paper proposes the use of a log-linear model to obtain long-range micro-level population projections from the aggregative projections. The proposed model is tested using U.S. data. The total population of households is decomposed into 120 subgroups on the basis of the household's region of location, age, size and the female's employment status. The estimated number of households from the log-linear technique is compared against the random-walk and time-trend methods. A comparison of the size of the observed and estimated subgroups for the years 1960 and 1980 suggests that the log-linear technique is superior to the other two methods. Five different measures of errors are used to evaluate the projections."

Age Factors↗

Population dynamics and consumer demand.

The authors analyze the effects on consumption in the United States of 11 demographic variables, including "regional location and the urban/rural base of the household, its age, size, race, sex and marital characteristics, and the education and the employment status of the household head and the spouse." Data are from the 1972-1973 Consumer Expenditure Survey. The expenditure functions are first specified, followed by descriptions of the data sources and the empirical estimates of expenditure functions for various items of consumption spending.

Socio-demographic dynamics and household demand.

The relationship between household characteristics and household expenditure in the United States is explored. "The basic hypothesis of this paper is that socio-demographic characteristics of households are important determinants of their expenditure patterns as are price and income variables."
