When did the decline of marriage begin in America? 

BLUF: 1985.  Joe Carter’s “why” is interesting:

What changed in 1985 that could have lead to the decline in marriage? There are likely numerous factors—which we’ll examine in future articles—but one stands out in particular: By 1985, all states (except for New York) had enacted no-fault divorce legislation.

Update: From Facebook: “It posits that the spike in divorces after WWII could be due to hasty pre-war marriages not surviving the war intact. It’s also quite likely that the generally ignored PTSD suffered by WWII vets had something to do with it.” No doubt about it.
