During the 17th century, the average lifespan across Europe ranged between 30 to 35 years. However, it is important to note that infant mortality rates were high, with many children not surviving past their first year of life. As a result, the average life expectancy at birth was lower.
In some regions, such as London, life expectancy was even lower, with an average of 25 to 30 years due to poor living conditions and rampant disease. On the other hand, in rural areas and among the upper classes, life expectancy could be somewhat higher, reaching 40 or even 50 years.
