Inferring Migration Flows from Birthplace-Specific Population Stocks
نویسندگان
چکیده
Demographic estimation in countries with well-developed data reporting systems is based on data collected by censuses and vital registration systems. In countries with inadequate or inaccurate data reporting systems, demographic estimation often must rely on methods that are “indirect”. Such methods have been applied with considerable success in studies of mortality and fertility, but they have not been developed as systematically and formally for the analysis of migration. This paper sets out and tests three alternative methods for indirectly estimating origin-destination-specific migration propensities that have identical input requirements: two successive, birthplace-specific multiregional population age distributions. Common to all three methods is a focus on the ratios of age-specific conditional survivorship proportions, ratios which mirror the regularities in age profiles that characterize migration schedules, suggesting that future research should be directed at linking these regularities with those of model migration schedules.

Analysis of Migration Flows to 22 Areas of Tehran
The political situation in Tehran has caused the city to become a commercial, industrial, administrative, educational and military center of Iran for decades. Such a situation has created waves of immigration and displacement of population from all over the country to the city. In order to understand the situation of the immigrant population of Tehran, this paper uses census data from 2006 and ...
متن کاملEstimating global migration flow tables using place of birth data
BACKGROUND International migration flow data often lack adequate measurements of volume, direction and completeness. These pitfalls limit empirical comparative studies of migration and cross national population projections to use net migration measures or inadequate data. OBJECTIVE This paper aims to address these issues at a global level, presenting estimates of bilateral flow tables between 1...
متن کاملEmigration flows from North Africa to Europe.
The region of North Africa (NA) represents a striking locality regarding migration with several migration patterns, namely emigration in the form of labour export to Europe and North America and, to a lesser extent, to the Arab Gulf area. The latter has increased enormously in the last decade because of the political instability in most of the NA countries. The aim of the present chapter was to...
متن کاملFine-scale estimation of location of birth from genome-wide single-nucleotide polymorphism data.
Systematic nonrandom mating in populations results in genetic stratification and is predominantly caused by geographic separation, providing the opportunity to infer individuals' birthplace from genetic data. Such inference has been demonstrated for individuals' country of birth, but here we use data from the Northern Finland Birth Cohort 1966 (NFBC1966) to investigate the characteristics of ge...
