Congressional District Analysis and Insights
  .. interpretative data analytics; tools, data & methods

April 2018 .. the 115th Congress (January 2017 through December 2018) becomes the 116th Congress (January 2019 through December 2020) following the November 2018 elections. Looking further ahead, the Census 2020 results, to be initially reported to states no later that March 31, 2021, is the basis for reapportioning the number of the U.S. House of Representative seats by state. With state by state redistricting to be completed by the November 2022 elections, the 119th Congress (January 2023 through December 2024) will reflect new boundaries -- and demographic make-up of those districts.

Main Congressional Districts Section
This is the "main" Congressional Districts section. See the updates section below that provides links to congressional district related topics focused data and tools to examine geographic, demographic and economic characteristics and change. These topics relate to a wide range of other geographies and data. These include states themselves, state legislative districts, cities/places of population concentration, counties administrative units of states and other geographic levels. Census blocks are the defining smallest geographic element of congressional districts. Increasingly, block groups and census tracts are important in the analysis of congressional districts due to the annual updates based on the American Community Survey (ACS) on the citizen voting age population (CVAP) for these smaller geographic areas.

Redistricting & the 115th Congress
Some states have redistricted and CD boundaries differ from the 114th CDs. For example, the North Carolina 115th CD 12 includes a total 2015 population of 830,225 with White alone population of 418,155. This compares to the NC 114th CD 12 total population of 793,964 with White alone population of 297,746. Not only do the population sizes and geography differ but wide-ranging constituency attributes also differ.
