The fertility transition in nineteenth-century England and Wales: a social class model?

"The changing relationship between fertility and the standard of living is examined in the long term. The model presented provides a means of focusing on the cross-sectional association between fertility, especially marital fertility, and social class during the nineteenth-century fertility transition in England and Wales. An inverse relationship is revealed by all four of the perspectives adopted, but the problems inherent in defining social classes and the significance of fertility behaviour particular to occupations diminish the value of very broad generalizations."
