50 years of American marriages

I find this graph to be particularly interesting because my grandfather, a staunch full-blooded Norwegian, was genuinely disturbed when my aunt chose to marry a Swede in the 1940, and only grudgingly permitted it.  Some years later, when I was a child, another uncle kept his even more radical marriage (to a Catholic!) secret from everyone else in the family for many years.

Now, my generation of the family has I think four interracial/interethnic marriages and one same-sex union, and no one thinks twice about any of them.

All this change within one lifetime.
