Urban populations had other problems ~ there, traditionally, adults could survive well but the children would die. It was common for wealthy urbanites to send their children to the country to grow up.
Industrialization, water purification systems, and modern medicine helped reverse the situation. Today the rural poor die while the cities are far healthier for everyone.
The error in your response to my post is that you selected mostly urban, or substantially urban residents. For their periods of time they were not typical of the bulk of the population that lived in a rural environment and suffered rural illnesses.
“Half a dozen wives was not at all unusual ~ particularly in rural areas where death in childbirth was exceedingly common.”
This is a pointless discussion, but I will point out that Washington, Jefferson and Jackson were all farmers.
You might have made a better case if you had based your criticism on class rather than location.
