ELI5: Is there an actual not racist reason basketball is largely made up of people who are black?
gpt
A large part of the black population is poor and urban.  Basketball is a sport that can be played in cities with very little room, and doesn't cost much.  Therefore, it's a sport that many of them have access to.  Baseball, football, etc, take up a lot more space.
