Louisiana Voting District Boundaries for 2020 Census

Voting district boundaries for the state of Louisiana, as provided by the U.S. Census Bureau for the 2020 Census. The data is part of the TIGER/Line shapefile series, designed as a seamless national file with no overlaps or gaps. Each voting district is identified by a unique 1- to 6-character alphanumeric census code within its county.

Use Cases

• Analyze voting district boundary changes by comparing 2020 VTD geometries with previous census years.
• Map Louisiana election results by joining vote tallies to VTD polygons using the unique census code identifier.
• Calculate demographic statistics per voting district by spatially joining VTD boundaries with Census population data.
• Assess geographic coverage of electoral representation by identifying areas without VTDs, noting that Montana and Oregon lack complete coverage.

Strengths

• Data originates from the authoritative U.S. Census Bureau Master Address File/TIGER Database (MTDB).
• Boundaries are topologically integrated, forming a seamless national file with no overlaps or gaps.
• Voting districts are identified by a unique 1- to 6-character alphanumeric census code within each county.

Limitations

• Coverage is incomplete for the 2020 Census, as Montana and Oregon do not have complete VTD data.
• No voting district boundaries exist for Kentucky and Rhode Island in the 2020 Census products.
• The dataset's size, row count, and specific column schema are not provided in the input.
