Cleveland Census Information

 

The City Planning Commission provides Census information for the City of Cleveland. The data is obtained from the U.S. Census Bureau and is then re-organized to meet local needs. The City Planning Commission groups the Cleveland Census Tracts into 36 neighborhood areas (known as Statistical Planning Areas or SPA s ), and then groups those neighborhoods into 6 Planning Districts. Information is also presented for the City's 21 wards.
