According to https://en.wikipedia.org/wiki/Life_expectancy https://en.wikipedia.org/wiki/Life_expectancy Rome was like this: > When infant mortality is factored out (i.e. counting only the 67–75% who survived the first year), life expectancy is around 34–41 more years (i.e. expected to live to 35–42). When child mortality is factored out (i.e. counting only the 55-65% who survived to age 5), life expectancy is around 40–45 (i.e. age 45–50). The ~50% that reached age 10 could also expect to reach ~45-50; at 15 to ~48–54; at 40 to ~60; at 50 to ~64–68; at 60 to ~70–72; at 70 to ~76–77. Early 19th century England > For the 84% who survived the first year (i.e. excluding infant mortality), the average age was ~46–48. If they reached 20, then it was ~60; if 50, then ~70; if 70, then ~80. For a 15-year-old girl it was ~60–65. For the upper-class, LEB rose from ~45 to 50. Less than half of the people born in the mid-19th century made it past their 50th birthday. In contrast, 97% of the people born in 21st century England and Wales can expect to live longer than 50 years.
