Assembly Districts are specific geographic areas within a state that are represented by elected officials in the state legislature. Each district elects a member to the State Assembly, which is responsible for creating and passing laws. The number of districts varies by state, depending on population size and legislative structure. These districts are designed to ensure that all citizens have representation in government. They are drawn based on population data from the U.S. Census, which occurs every ten years. This process, known as redistricting, helps maintain equal representation as populations change over time.
