## Additional Notes
MEDSL precinct-level data was checked against county-level election results. Those results were compiled by RDH staff using PDF files from the Mississippi Secretary of State with precinct-level data for each county, retrieved 9/13/23. (https://www.sos.ms.gov/elections-voting/2022-general-election-results)

All results matched.

However, a previous version of the MEDSL data (retrieved 9/7/23) was checked against those same county files from the Mississippi Secretary of State.

Totals matched in every county except for the following: Sharkey, Tallahatchie, Lee, Pontotoc, Jackson, Pearl River, Clarke, Oktibbeha, Neshoba, Rankin

There were discrepancies in 11 of 1757 precincts. In cases where precinct results did not match, MEDSL data was replaced with state data. That resolved all discrepancies.

The election results file on the RDH website was correct and remains unchanged, but we note the use of updated data from MEDSL. Full details on processing of the most recent MEDSL data can be found in the notebook linked below.

Shapes were sourced from VEST and respective county website and correspondences listed above.
