According to the U.S. Census Bureau, Williamson County's population has risen by 35.23% in the past 10 years, rising from 183,182 in 2010 to 247,726 in 2020.
Due to that population change, the county, along with the state, will be required to review population numbers throughout the county to ensure voting districts have equal population sizes.
"In a few months we'll have the census data that's coming in, and we'll need to review the average number of constituents currently serving within each of the county's 12 voting districts," County Mayor Rogers Anderson said during Williamson Inc's State of the County event July 28. "The county commission has established members of the reapportionment committee to review the current district and revise them in accordance with the new population statistics."
Anderson said population sizes in each district must be within 5 percentage points of neighboring districts.
Because the county's districts are also used to determine Williamson County Schools Board of Education representation, some residents could also see changes in who represents their neighborhood. The redistricting will also redraw legislative voting districts.
"Many of our voters will be assigned a new elected representative for state and federal voting districts," Anderson said.
Following the reapportionment committee's analysis of the population data, new voting districts are expected to be sent to the Tennessee General Assembly this fall for approval. The county is expected to finalize new districts by Dec. 31, according to County Elections Administrator Chad Gray.
