Redistricting is the process of redrawing electoral boundaries. It occurs for all levels of representative government, including the US House of Representatives, state legislatures, local voting districts (precincts), and more. These boundaries define the constituency that will be represented in government and the district in which a candidate for office runs.
The US Constitution requires a census of the population and a reapportionment of congressional representatives every ten years. After each new census, states and local governments redraw voting districts to account for changes in population and geography that have occurred over the preceding decade. The 2020 census counted just over one million residents in Rhode Island and 17,153 residents in Barrington.
