Congressional District Citizen Voting Age Population

.. congressional districts are very diverse in terms of the overall percent and geographic distribution of citizen voting age population. The size and distribution of the citizen voting age population are important as this population group determines election outcomes. Among the 114th Congressional Districts, the citizen voting age population (CVAP) ranged from 43.2% of the total population (CA40) to 81.2% (FL11) in 2014. Nationally, the citizen voting age population (CVAP) was 70.5% of the total population

Examining patterns of the citizen voting age population … the Voting Rights Act prohibits development of voting districts that discriminate against potential voters on the basis of race and/or language minority status. To examine how voting districts comply with the Voting Rights Act requires data on the citizen voting age population (CVAP) by race/origin for many types of geographic areas. This section provides data analytics tools to examine ACS 2014 1-year CVAP estimates for 114th Congressional Districts. See related section for information CVAP demographics at the census tract level.

The CVAP data can be used to develop insights into alternative interpretations of “one person one vote.” The Supreme Court on May 26, 2015, agreed to hear a case that will answer a long-contested question about a principle of the American political system — the meaning of “one person one vote.” The court has never resolved whether that means that voting districts should have the same number of people, or the same number of eligible voters. The difference matters in places with large numbers of people who cannot vote legally, including immigrants who are here legally but are not citizens; unauthorized immigrants; children; and prisoners.

The CVAP estimates provide only one part of the required data. Voting district and other boundaries and data are also needed to be used in combination with the CVAP estimates. Using GIS tools, the CVAP estimates can be used in mapping applications, such as those reviewed in this section, in combination with voting district boundaries to reveal potential non-compliance in the structure of voting districts.
