What was life expectancy in 1823?

Answer 1

In 1823, life expectancy varied significantly by region and socioeconomic status, but it was generally much lower than today, averaging around 30 to 40 years in many parts of the world. High infant mortality rates and the prevalence of Infectious Diseases contributed to this low average. In more developed areas, life expectancy could be slightly higher, but it remained limited by medical knowledge and public health conditions of the time.
