How many slaves out of 100 lived to be 60 years old?

It is difficult to provide an exact quantitative response due to limited reliable historical records from that time period and the diverse experiences of enslaved individuals under widely varying circumstances. In general, mortality rates during the transatlantic slave trade and in conditions of involuntary servitude were high due to factors such as disease, physical abuse, insufficient nourishment, poor working conditions, and a lack of proper healthcare. Life expectancy was drastically lower compared to people living in freedom. Thus, only a small fraction lived into advanced age. Additionally, life expectancy also likely varied based on region, plantation/working conditions, the treatment individuals received from their 'masters,' and chance circumstance and access to care when in old age.
