The average Census District is between 400 and 600 dwelling units, however, some size differences occur, particularly in growing areas. Census Districts are defined in the "Civic Census General Instruction Manual" as being a subdivision of a Voting Subdivision. These Census Districts will come into effect on Election Day (October 16) 2017.
