I have heard people mention "The Carolinas" from time to time as if they are one state. But they are not, despite the name of the football team in Charlotte.
North Carolina became a state in 1789, has a median household income of $54,082 and a population of 9,943,964. On the southern side, South Carolina has a population of 4,832,482, a household median income of $44,625, and became a state on May 23, 1788.
Which state is better and why? What makes them different?
