Every 10 years new maps are drawn because of the Census. Populations change and demographics shift to different areas. In an effort to make sure people are equally represented the maps a redrawn to adjust to changes.

New York was particularly bad this year as map after map was rejected by Democrats and Republicans. In the end, a panel of federal judges had to draw the new maps.
