  abstract      = {We hypothesize that the timing of the fertility transition
                  is an important determinant of comparative physiological
                  development. In support, we provide a model of long-run
                  growth, which elucidates the links between population size,
                  average body size and income during development.
                  Industrialization is shown to be accompanied by a reduction
                  in family size and an intensi cation of nutrition per
                  child. Early transition countries are therefore expected to
                  be more developed today, economically and physiologically.
                  Empirically, the timing of the fertility transition is
                  strongly correlated with average body size across
                  countries.}
