Missouri's Changing Legislative Boundaries

<p>While the decennial US Census is used to determine the distribution of funds for, among other things, infrastructure, education, and healthcare, the creation, elimination, and alteration of legislative districts may very well be the single most important change based on updated population estimates. Changes to the districts that determine the composition of the US House of Representatives typically (and understandably) receive the majority of attention in the wake of a new Census, but state legislatures are just as malleable and changes to those boundaries have a much bigger impact on local politics. </p><p>The maps featured in this application highlight the changes to both the Missouri House and Senate boundaries after the 2020 US Census. Each chamber is represented by its own swipe map, the Missouri House first and the Missouri Senate second. The red outlines on each map (the left side of the swipe tool, in this case) indicate the new, post-2020 districts while the blue outlines (the right side) represent the previous boundaries. Left-clicking on any district will open a pop-up window identifying the district number and, for the newer boundaries, the current office holder.</p>
