I don't recall abortion on TV shows being common in the 1970s and 1980s.
I also am curious about the rate of marriage for females before 200 years ago, I sure don't think there were many in America, or anywhere else actually.
Here is an example from a book describing Medieval British Society, 1066 1485 ""As many as 94 percent of the peasant farmers were married. ""
Here is one example. Now, illegitimate births are higher now, but they were not as low as we like to think they were 200 years ago. This site suggest it was about 37% or so of first births were before marriage. There are many other sites with similar information on the net. Ran into this researching family history, when I noticed a lot of births before marriage.
For the shows, I remember Dr Quincy MD (also had a man getting a trans-gender surgery), some of the soaps my Mom watched (for some reason I think Falcon Crest, but since I never paid close attention I may be wrong). These would have been in the early 1980’s or so. General Hospital had a few episodes about it, as did a number of sit coms I can't remember the name of.
I do remember my Dad telling me about what abortion really was after one of those shows.
Thanks for your patience. Typing on a phone sucks.
