Approximately how many special districts are there in the united states?

Special districts encompass a form of local government formed by a local community to meet a specific need. Insufficient tax bases and opposing demands for existing taxes make it difficult for cities and counties to provide all the services their citizens need. In the United States, there are about "more than 30,000 special districts."

regarding the law, the 15th amendment was specifically designed thinking in the rights of black free men.

even though ratified on february 3, 1870, the promise of the 15th amendment would not be fully applied for a long time.poll taxes and literacy tests would allow southern states disenfranchise african americans. only in 1965 the voting rights for african americans would be actually able to vote in the south.

in 1965, president johnson signed the voting rights act, which aimed to overcome legal barriers that prevented african americans from voting as it was guaranteed by the 15th amendment to the u.s. constitution.
