Obtaining reliable and timely estimates of migration flows is critical for advancing the migration theory and guiding policy decisions, but it remains a challenge. Digital data provide granular information on time and space, but do not draw from representative samples of the population, leading to biased estimates. We propose a method for…

Background: Singapore is experiencing great demographic change. These demographic trends show fewer young people and declining birth rates, greater longevity for ageing generations and an increase in the number of non-Singaporean residents. Statistics also show that more than half of the total population increase in the last decades was…

Second-generation immigrants are typically analyzed under the assumption that, having been born in the United States, they grew up in the United States. We challenge this assumption by investigating the prevalence and patterns of second-generation Mexican-American children's migration to and return from Mexico during childhood, and consider the…

This paper analyzes geographic patterns of population concentration and deconcentration among the foreign-born population during the 1990-2000 period. A goal is to examine whether the foreign-born population, including recent arrivals, are dispersing geographically from metro gateway cities into rural and other less densely populated parts of the…

Existing data on illegal immigration in the U.S. is inadequate. The limited availability of macrodata on the size of the annual flows and of the accumulated stock of individuals as well as of microdata on their influence on selected labor markets has been used to forestall policy reform efforts.

In this study migration is examined as a component of population change. Decisions involved in migration are discussed. Source of migration data are suggested. Generalized in-migration and out-migration fields are described. Migration patterns before 1975 and recent migration patterns are examined and decisions underlying the latter are analyzed.…

Compares the 1980 census count of aliens with estimates of the legally resident alien population based on data collected by the Immigration and Naturalization Service in January 1980.

The purpose of this research project was to compile and analyze data concerning the composition and geographic distribution of South Africa's population for the purpose of future educational planning to meet the needs of four population groups. This document contains statistics and conclusions on: (1) the role of population shifts and…

This paper reviews issues pertaining to the relationship between child mortality and fertility and examines the fertility-mortality relationship of women who emigrated to Israel from various countries in Asia, Africa, and Europe and continued child bearing in Israel. Data from the 1961 Israel census of population is used. Among issues addressed in…

Uses 1980 Public Use Microfiles to delineate four Mexican-origin immigrant status groups--post-1975 Mexican-born noncitizens, pre-1975 Mexican-born noncitizens, self-reported naturalized citizens, and native-born Mexican Americans. Argues that the pattern of sociodemographic differences reveals that the first two categories contain a substantial…

Addresses out-migration from and in-migration to metropolitan areas in the United States and particularly the effect of the social-welfare system on migration decisions. The results provide only weak support for the hypothesis that social-welfare benefits influence out-migration decisions but moderate support for its influence on in-migration.…

This analysis addresses the need for including age-structure effects in migration analysis as important for determining effects of a demographic process on an area's socioeconomic characteristics. It examines: (1) patterns of age-specific net migration across age groups for Texas' 254 counties in 1960-1970 and 1970-1980 using cluster analysis and,…

This study tried to determine the internal and external migration patterns as established by high school graduates of 1960, in rural Nebraska, and the association of educational, psychological, geographic, and economic factors with their migration and educational plans. Data for the study of the 4700 graduates were provided by almost 300…

This research study attempts to provide a fuller understanding of policy-related and technical aspects of the migration process. The study bridges the gap between previous research and present concerns of policymakers. The report draws upon longitudinal household data; employs new methodological techniques; and defines explanatory variables to…
