I have the percentages for different age groups in 18th century Peru;
not quite what you asked, but it gives you an idea:

0-9: 24%
10-19: 20%
20-29: 17%
30-39: 15%
40-49: 11%
50-59: 7%
60-69: 4%
70+: 2%

Actuaries have tables of life expectancy at various ages, and these were
first calculated by Edmond Halley. His paper on the topic for the Royal
Society is available at
