A census is what this is called. A census (depending on the type and by who is conducting it) basically counts something like the number of people in the population so that whoever is using it can get accurate results for something. Like lets say a king wanted a census of his people, animals, soldiers. He would instantly have his men count all the people in the city. They would record the amount of animals. And the same for soldiers. Then they would put all this information in a big book and keep it in the palace. It was frequently updated as people moved or died.
In this case, any value given up by not choosing to
<span> spend or save the money is the "opportunity cost", because the money </span>could be spent elsewhere. "trade offs" and opportunity costs are very similar though in economics.
Making a colony should be the last one. :)
It was around the civil war time in the south when white people and black people were separated... also called segregation
