title: L2 Voter and Demographic Dataset

description: If you have questions or concerns, please contact Vijoy Abraham at vijoy@stanford.edu.


description: The L2 Voter and Demographic data is current as of March 04 2022. The data includes demographic and voter history tables for all 50 states and the District of Columbia. The dataset is built from publicly available government records about voter registration and election participation. These records indicate whether a person voted in an election or not, but they do not record whom that person voted for. Voter registration and election participation data are augmented by demographic information from outside data sources.
description: To create this file, L2 processes registered voter data on an ongoing basis for all 50 states and the District of Columbia, with refreshes of the underlying state voter data typically at least every six months and refreshes of telephone numbers and National Change of Address processing approximately every 30 to 60 days. These data are standardized and enhanced with propriety commercial data and modeling codes and consist of approximately 185,000,000 records nationwide.


description: For each state, there are two available tables: demographic and voter history. The demographic and voter tables can be joined on the 'LALVOTERID' variable. One can also use the 'LALVOTERID' variable to link the L2 Voter and Demographic data with the L2 Commercial data.



One can also use the 'LALVOTERID' variable to validate the state. For example, let's look at the 'LALVOTERID' for one row in the CA-Demographic-2022-03-02 table. The characters in the fourth and fifth positions of this identifier, LALCA123456789, are 'CA' (California). The second way to validate the state is by using the RESIDENCE\_ADDRESSES\_STATE, which has a value of 'CA' (California).



The date appended to each table name represents when the data was last updated. Many tables were updated 2022-03-02, but there are some exceptions (e.g. FL-Demographic-2021-12-14).



The demographic files use 691 consistent variables. For more information about these variables, see ***2021-11-03-L2-Voter-Demographic-File-Layout.xlsx***.



The voter history files have different variables depending on the state. The ***2022-03-04-L2-Voter-Data-Dictionaries.tar.gz ***file expands into .csv data dictionaries for each state's demographic and voter files. While the demographic file data dictionaries should complement the 2021-11-03-L2-Voter-Demographic-File-Layout.xlsx file, the voter file data dictionaries will be unique to each state.



***Experian\_Mosaic\_Guide.pdf *** is a codebook for two variables which appear in the demographic tables: 'CommercialData\_MosaicZ4' and 'CommercialData\_MosaicZ4Global.'

title: L2 Voter and Demographic Dataset

description: The data found within this L2 Voter Dataset is current as of May 2021 and contains 55 files; 51 for "voter" data and 4 for "demographic". This data includes all 50 states and DC.
description: #Documentation  
<u><em><strong>Demographic Data</strong></em></u>

The demographic data is found in four tables (2018-Demographic, 2019-Demographic, 2020-Demographic, 2021-Demographic). The schema for these four files differs year over year. There are two ways to tell which state a voter is in for that year. The first way is using the \`LALVOTERID\`, which is a unique identifier. For example, let's look at the \`LALVOTERID\` for row in California. The characters in the fourth and fifth positions of this UID, LALCA123456789, identifies "**CA**" for California. The Second way to identify is using the RESIDENCE\_ADDRESS\_STATE, which would have a CA for California.



<u><em><strong>Voter Data</strong></em></u>

There are 51 voter files (50 states and DC) containing appended election data (columns) going back decades (in some cases back to 1992). Each table is named with the recent date, state abbreviation, and data type. So for California, you will use \`2021-CA-Voter\`, which is the California Voter data for 2021 and back.

The characters in the fourth and fifth positions of this identifier are 'CA' (California). The second way to validate the state is by using the `RESIDENCE_ADDRESSES_STATE `variable, which should have a value of 'CA' (California).



The date appended to each table name represents when the data was last updated. These dates will differ state by state because states update their voter files at different cadences.



The demographic files use 698 consistent variables. For more information about these variables, see ***2025-01-10-L2-Voter-Demographic-File-Layout.xlsx***.



The voter history files have different variables depending on the state.
