Looks like about 130 million in 1940, and 327 million now. That would get a little over two and a half times the population since birth for someone who is 77-78.
Really not that far from 3X, as a rough estimate. Certainly not cause for snide derision.

Where is the "snide derision", Lurkerbreath?
I merely wrote in post 314, "Itsahoot......... you're one hell of an old guy, or you are one hell of a near old guy who is making a GOOD POINT .... yet exaggerating."
If you, Lurkerbreath, consider that derision of any sort, you are an oversensitive misguided individual. Get a grip.
You also may want to know that being called "one hell of an old guy" is NOT derision. It's a COMPLIMENT.
Get that grip.
My memory from grade school days (I don’t recall what grade, but my HS graduating class was ‘61)) is the figure 180 million.
