Yes. I went looking for life expectancy at 20 in 1830s France but could not find it via casual Googling.
EDIT: Ah, should have gone straight to Wolfram Alpha: The answer is that if you lived to be 20 odds were you'd live to 60. Unless, alas, you were Balzac.
Alpha is the amateur demographer's dream. Just look at those tasty charts and graphs. Of course I didn't read closely enough to figure out where this data was coming from. ;)
