In this paper, we investigate the issue of partner selection in the health of individuals who are at least fifty years old in England and the United States. We find a strong and positive association in family background variables including education of partners and their parents. Adult health behaviors such as smoking, drinking, and exercise are more positively associated in England compared to the United States. Childhood health indicators are also positively associated across partners. We also investigated pre and post partnership smoking behavior of couples. There exists strong positive assortative mating in smoking in that smokers are much more likely to partner with smokers and non-smokers with non-smokers.
