Virginia Get-Out-The-Vote Maps

FairVote2020 has developed two separate interactive map applications showing voter registration in Virginia by precinct as of 2000. The first -- Unregistered Over 18 Population in 2000 by Precinct -- shows the unregistered population at the time of the 2000 election. The second -- Registered Voters by Party in Southside Virginia -- shows registered voters and political party affiliation based on a geocoded list of registered voters in the area encompassing the old 4th Congressional district in Southside Virginia (106th Congress). Red colors indicate areas of low voter registration in both applications.

Additional maps include census data on race, ethnicity and income. Change maps by clicking on the map under "Compare Maps" on the left. You may zoom in on the map by clicking on the appropriate button at the top and then on the map.


Unregistered Over 18 Population in 2000 by Precinct

Google-FairData Base Map (start with a Google map interface)


Map 1 (default map) -- Percent Unregistered over 18 in Virginia ( 2000 precincts)

At a scale of about 5 miles, the number of voting age persons who are not registered to vote is displayed in purple boxes. This number has not been adjusted for non-citizens. Precinct boundaries are those in effect in 2000. Pie charts display in areas with significant minority population, showing race/ethnicity components for the over 18 population.

***************

Application 2

Registered Voters by Party in Southside Virginia (2001 data)


Map 1 (default map) -- Registered Voters by Party in Southside Virginia (2001 data)

Geocoded to block level -- based on early 2001 registration data in Congressional District 4 prior to the 2001 redistricting. Approximately 3% of registered voters are excluded due to geocoding inaccuracies. Additional discrepancies between 2001 voter data and the 2000 census result in some blocks showing more voters than voting age population. A geocoding issue in and around Wakefiled in Sussex County results in a significant undercount of the registered population at the block level in that area.

No adjustments have been made for prison populations. Precinct boundaries (VTDs) do not reflect changes made in 2001.Block-level themes display at 5 miles, political party charts at 3 miles.
