How did Virginia's population change after 1619

The state of Virginia has always been quite diverse. But in the year 1619, it witnessed a massive inflow of Africans creating a cultural mix which became a part of Virginia. And the easiest way to earn more money in the state of Virginia was to grow tobacco. But the Native Americans failed to get the labor from the people. At first they relied on hiring labors from England and Europe. But this didn't give them the number of workers they needed. Finally Virginia created its own slavery system. In this system the son born to a slave mother had to serve a slave for his entire life.
