Prediction in 1940: by 1970, u. s. population would be 147 million. Actual population in 1960: 204 million. Average number of children per family increased from 2 in. 1940 to 3. 57 in 1957: 1) the pace of childbearing increased. Meant that couples had a long time at risk of having additional children: 2) booming post-war economy. Families could afford more children: 3) socio-cultural changes. Both men and women: desired a return to normalcy . Family: desired to make up for lost time . All these changes worked together to set up conditions for couples to add a third or fourth child: they preferred two, but relaxed their contraceptive vigilance . Inflation increased: inflation: cost of goods increased, while getting the same amount.
