Title: Precincts 2020

Geospatial_Data_Presentation_Form: vector digital data

Description:

Abstract:

The 2020 Precinct data set represents the geography used for the 2020 election cycle. Information was collected from local election officials along with county/local GIS authorities as well as a validation done by most, but not all jurisdictions. BOE maintains every effort to keep this data correct, however the data set is only as good as the information received from the local election official.

Purpose:

In the past Census Voter Tabulation District (VTD) data was the closest available for election precinct geographic data, however it was not entirely accurate. The Michigan Bureau of Elections with assistance from the Michigan Center for Shared Solutions started a project to work with local election officials and county/local GIS authorities to create accurate 2016 precinct boundaries and maintain the boundaries going forward with their assistance.

Supplemental_Information:

VTD boundaries were adjusted based on various information collected from local election officials as well as county and local GIS authorities. The finished boundaries were provided to the local election officials for review and comment.
