In 1935, the United States passed Social Security Act (SSA) providing financial security to American families. I use the individual census data for 1940 and 1960 to show that women from states that allowed for more social spending under the SSA had substantially more children than women from states that allowed for lower social benefits. I also use a new panel of state-level fertility by parity between 1935 and 1959 to show that family allowances were connected to first, second and third parities, but that there was a differential effect according to the different social programs and race.
