How is legislative redistricting handled in Missouri?

Legislative redistricting in Missouri is conducted every ten years after the census. This process is critical because it ensures that the representation in the state legislature reflects changes in population and demographics. Following the decennial census, population shifts can lead to changes in the number of residents in various districts. To maintain equal representation, districts are redrawn to align with these population changes, adhering to the principle of "one person, one vote."

The ten-year cycle aligns with the federal guidelines for redistricting, which also operates on a decennial basis following the U.S. census. This synchronization helps ensure that representation is effectively adjusted in a timely manner to reflect the most current demographic data, allowing for fair and equitable voting districts throughout the state.
