Analyses utilizing the alternative article-beginning homogamy measure complete with lovers up to 18 decades shortly after the initial beginning are consistent with all of our head conclusions (look for Dining tables A7 and you can A8, on line appendix)
I subsequent disaggregate which decomposition to your a couple of periods: changes anywhere between 1968 and you will 1990 (committee B) and alter ranging from 1990 and 2015 (panel C).
