The Court had found that Louisiana and a number of other states had failed to reapportion their state legislatures for decades, in many cases keeping representation based on geographic boundaries, such as counties or parishes, rather than population. This had resulted in under-representation for decades of urban and industrialized districts in the state legislature. Redistricting was also required at the parish level for election of police juries. By the constitution, reapportionment (or redistricting) of the parish is required following each official census. This can change the boundaries of the single-member districts, to ensure that each Juror represents approximately the same number of people.
