1,000 during the same period. Marriage instability in early adulthood contributed to their high rate of divorce. For comparison, the divorce rate for that same period for people aged 25 to 39 went from 30 down to 24, and those aged 40 to 49 increased from 18 to 21 per 1,000 married persons. According to American demographer Philip Longman, "even among baby boomers, those who wound up having children have turned out to be remarkably similar to their parents in their attitudes about 'family' values". In the postwar era, most returning servicemen looked forward to "making a home and raising a family" with their wives and lovers, and for many men, family life was a source of fulfillment and a refuge from the stress of their careers. Life in the late 1940s and 1950s was centered around the family and the family was centered around children. Among Frenchwomen born in the early 1960s, only a third had at least three children. Yet they were responsible for more than half of the next generation because so many of their contemporaries had just one or even none at all. In the United States, one-fifth of women born in the 1950s ended their fertile years without giving birth. 17% of women from the Baby Boomer generation had only one child each and were responsible for only 8% of the next generation. On the other hand, 11% of Baby Boomer women gave birth to at least four children each, for a grand total of one-quarter of the Millennial generation. Those who had many children were likely religious (especially practicing Christians) while those who chose to remain childless were often members of countercultural or feminist movements of the 1960s and 1970s. Because parents wield a great deal of influence on their children, this will likely cause cultural, political, and social changes in the future. For example, by the early 2000s, it had already become apparent that mainstream American culture was shifting from secular individualism towards religiosity. Due to the one-child policy introduced in the late 1970s, one-child households have become the norm in China, leading to rapid population aging, especially in the cities where the costs of living are much higher than in the countryside.
