The Child Health and Development Studies investigate a range of topics. One
study, in particular, considered all pregnancies between 1960 and 1967 among
women in the Kaiser Foundation Health Plan in the San Francisco East Bay
area. We do not have ideal provenance for these data. For a better documented
and more recent dataset on a similar topic with similar variables,
see births14. Additionally, Gestation dataset in the
mosaicData
package also contains similar data.
