What were the special characteristics of the population of Virginia in the seventeenth century?
There were a number of things about Virginia's population that could be called "special characteristics." Most of these characteristics came from the fact that Virginia's economy was a plantation economy.
Because of this, the people who came to Virginia tended to come as individuals rather than as families. Many of them came as forced labor. This meant that Virginia had a population with many single men and also many African slaves. At the top of this society was a small layer of rich planters.
Thus, Virginia's plantation economy led to a population that was disporportionately male, that had a significant number of blacks, and which was very unequal in economic terms.
