A simulation model for migrations and dispersals of prehistoric human populations
A new simulation model has been constructed to estimate demographic processes of prehistoric human populations who migrated and dispersed, particularly to uninhabited habitats; this model simultaneously treats fertility, mortality, and migration, taking the carrying capacity of the land into account. Our preliminary trials have produced satisfactory results. The applicability of this model to historical reconstructions is also discussed
The Effect of Migration on Maximum Opportunity for Selection
The effect of migration on the maximum opportunity for selection is analysed using koseki data, the Japanese family registration records, of a village population in a small island. When selection intensity is divided into two components, migration greatly influences the variance of the mortality component of the original formula. The difference in selection intensity, with and without allowance for migration, is conspicuous in the recent cohort; …
Demographic characteristics and their genetic implications in a small island
The family registration records from a village population in a small island of Japan are used to assess the effect of demographic differentiation within a population on genetic measures. When the couples studied are classified by birth cohorts and origins, wives of the couples where one spouse came from elsewhere were older at marriage and had a shorter duration of marriage or registration than wives where both spouses were natives of the village…
Mortality of an urban population by period of residence in a rapidly industrialized city
Mortality differentials among urban residents who were classified by period of residence in a rapidly industrialized city were analysed for those aged 20 and over dying between April 1974 and March 1978. The highest mortality in the male population appeared in the group with under 5 years of residence, and this was attributed to the high age-specific death rates at age 50 and over. In females, a mortality excess conspicuous in those under age 50 …
