If a nation has a lot of a resource, lets say oil, then they will prosper based on oil. People need oil, so they can sell it for high price and a lot of it since they own the land it's on. They start to get more money into their area, more pay towards them and they begin to thrive. This is varied on experience though based on the economical system that nation has decided upon. There's three major economical systems: traditional, command, and free enterprise. Traditional means that if your a family of fishermen, you'll be a fisherman. Command economy is more like communism, if you're good at something then you will be trained in that specifically. Free enterprise is capitalism, the best economical system.

The issue of whether or not slaves would count towards the population was a huge problem at the Constitutional Convention. Northern politicians did not want slaves to count, as this would give Southern states more power in Congress. On the other hand, Southern politicians wanted slaves to count but they did not want to give them equal rights. Ultimately, the two sides compromise by creating the Three-Fifths Compromise.
The 3/5ths Compromise stated that for every 5 slaves, 3 would count towards the population.
