Data on birth weights and the percentage of stillborn babies during th
e late nineteenth and early twentieth century, taken from hospitals re
cords in Edinburgh, Vienna, Dublin, Boston, Montreal and Philadelphia
reflect the social class and living standard of their patients as well
as socio-economic developments in these cites. To the extent that the
se hospital records also contained information on the mother's age, pa
rity, occupation, ethnic and religious background, marital status and
gender of the child, some inferences can be made on influences on intr
auterine growth and birth outcome.
