The influence of number and ages of children on residential mobility

Abstract

Abstract Married couples without children are more geographically mobile than those with children, at least through age 45. Among husband-wife couples with children, ages of children exercises a consistent mobility differential; when age of family head is controlled for, families with children under 6 years old only are the most mobile both within and between counties, followed by those with children under 6 and 6–17 years old, and followed in turn by families with children 6–17 years old only. The relationship between number of children and the probability of moving within counties has a reverse J-shape for family heads at each age under 45; after age 45 the relationship assumes a more normal J shape. Number of children is inversely related to the probability of migrating (moving between counties) for husband-wife families in which the husband is under 35; after age 35 the relationship is erratic. The effect of ages of children generally holds for each size of family. Female family heads with children are generally more geographically mobile than male family heads (wife present) at the same age and with the same number and ages of children present.
