were in general similar, increasing respectively
from 12.8 and 12.6 per 1,000 live
births for first births to 30.6 and 30.5 for
those of fifth and higher orders.
Although mortality for birth order 5 and
over is given only for that group as a whole,
the death rates increase markedly within
that group to very high rates for those of
10th or higher birth orders, as was shown by
Woodbury (1925) in his study of mortality
in eight cities in the United States. Thus,
in projects of the Investigation, when large
proportions of the infant deaths were of
fifth or higher birth orders, as in Recife,
many infant deaths would be of very high
birth order. In 11 Latin American projects
the proportions of infant deaths in the group
of birth order 5 and ,ver were above 30
per cent, namely:
