A workshop on biosocial models of demographic behavior was organized t
o provide information to members of the Social Sciences and Population
Study Section (SSP), the group entrusted by the National Institutes o
f Health (NIH) with the responsibility for conducting the first level
of peer review of demographic applications submitted to NIH for possib
le funding. Some of the variables studies by demographers are biologic
al, e.g., fertility, fecundity, morbidity, and mortality, so demograph
ers are not unaware of biological variables. However, they tend to tre
at biological variables as something to be explained by social, econom
ic, and psychological factors rather than to be integrated into an exp
lanatory paradigm. This workshop contains papers that focus upon vario
us stages of the life cycle and explore the importance of biosocial va
riables in explaining selected aspects of human behavior.
