The interrelation of fertility and geographic mobility in Peru: a hazards model analysis

The effect of place of residence and migration on fertility and the effect of fertility on migration have been long-standing concerns in population studies. This article makes use of novel longitudinal data from the Peru Demographic and Health Survey and associated statistical techniques to estimate these interrelationships for women of childbearing age. In the case of fertility outcomes, results are consistent with the findings of others that age and education are negatively associated with fertility. Residence in a city (versus countryside) predicts lower fertility, but residence in an intermediate size town has no effect. Results are somewhat less robust for migration outcomes, but indicate that education and having fewer children are positively associated with geographical mobility. Town and city residents are more likely to be movers; yet, among movers, these more urbanized individuals exhibit slightly lower rates of subsequent mobility. When compared to previous research, our results demonstrate the value of detailed temporal measurement of the outcome event and its associated covariates. -Authors
