In addition to the paper cited before he is also the author of Riley (2001) Rising Life Expectancy: A Global History. Ancient Through Pre-Industrial Times Unhygienic living conditions and little access to effective medical care meant life expectancy was likely limited to about 35 years of age. The before mentioned medical technologies has expanded the human life expectancy from 10-45 to 25-65years.

Part 3 Epidemiologists refer to this period in which life expectancy began to increase substantially as the health transition. Life tables are not just instrumental to the production of life expectancy figures (as noted above), they also provide many other perspectives on the mortality of a population.

The country-by-country estimates for 1800 come with a considerable uncertainty and to not give a false sense of certainty I have not added these estimates into the map, but the estimates for life expectancies are considerably lower than 40 years as is also shown for the regional and global estimates so that it is safe to assume that showing a life expectancy of less than 40 years on the map is correct. Then there are tombstone inscriptions and grave epigrams, such as this one for a woman who died in Alexandria in the 3rd Century BC. Smaller breeds of horses tend to live longer than larger ones. Once we have estimates of the fraction of people dying across age intervals, it is simple to calculate a life table showing the evolving probabilities of survival and the corresponding life expectancies by age.

Data for 1800 is scarce and when not available for a particular country data for 1820 was used.
