Question

Quizplus · Accepted Answer

The presence of more families and greater stability of population in Massachusetts allowed for a better living environment, access to proper nutrition and sanitation, and a lower incidence of diseases. The southern colonies and Caribbean, on the other hand, had a higher reliance on slave labor and a more transient population, which contributed to a higher mortality rate. The other choices, such as climate or reliance on indentured servitude or religion, do not fully explain the differences in mortality rates.
