A survey of Census Bureau population projection methods

"Population projections methods of the U.S. Census Bureau draw upon several different traditions of forecasting: demographic accounting, judgmental, time series, deterministic, and explanatory. This paper reviews each of the forecasting traditions in population projections, describes the U.S. Census Bureau's current methods for national and state population projections, and proposes new hybrid approaches such as demographic-time series methods for national fertility projections and economic-demographic methods for state migration projections. Throughout the article, possible parallels with forecasting in other disciplines are noted."

Migration as a demographic response: the age differentials

"This study uses the theory of demographic response as the background against which regional human migration is examined as a response to selected environmental conditions for the 1,056 counties in the North Central Region [of the United States]. Specifically, this study addresses two migration-related questions concerning county populations in the North Central Region: (1) What are the socioeconomic, demographic, and ecological factors to which county populations respond in adjusting their migration behavior? (2) Do socially important age cohorts respond to these factors differently or in a similar manner?" Factors affecting migration are employment status, income levels, educational status, ethnic group, residence location, marital status, home ownership, and age. Data are from the U.S. Census Bureau for the period 1965-1970.

Internal migration in India in the seventies: a demo-economic analysis

"This paper is aimed to address mainly the following three aspects of spatial mobility within India during the last inter-censal decade of 1971-1981: (i) Levels of inmigration, outmigration and net migration in the major states (ii) estimates of state-to-state migration flows and (iii) some insights on the socio-economic determinants of internal migration."

Gonorrhea and female infertility in rural Uganda

We studied sociocultural and medical factors in the Teso District in eastern Uganda and the Ankole District in western Uganda to discover the cause of the low and high fertility rates in these respective districts. The findings related to gonorrhea in women are presented in this article. Gonococcal cervicitis and clinical evidence of salpingitis occurred significantly more frequently in Teso (18.3% and 19%, respectively) than in Ankole (2.4% and 5.9%) women. Significantly more of the husbands of the gonococcal-negative infertile women compared to gonococcal-negative fertile women were found to have active gonorrhea, a past history of urethral discharge, and bilaterally thickened epididymides.
