Using the Map Tools: The map tools are located above the map and require a follow-up click on the map to activate.

Note: This legacy web mapping application performs best with Microsoft Edge or Internet Explorer.

Load the initial map page in Edge, right-click on the browser tab that contains the map -- then click on "Reload Tab in Internet Explorer mode", then turn on the button "Open this page in Compatibility view" in the pop-up.

If you are still using Internet Explorer, you may need to make an adjustment to the browser settings in order for the address and block group information for a searched address to display below the map. You can see the Internet Explorer version you are using by clicking Help on the browser, then About Internet Explorer. On the Internet Explorer menu bar, click Tools, then click Change Compatibility View Settings, then under Add this website, type and then click Add.

Zoom To tool:

Click the Zoom To tool and click on the map to immediately zoom to the geographic area nearest the spot where you clicked. For location-specific searches, use the Find button to access a form as described below.

A table with selected demographic data for the clicked area displays below the map.
  Info tool:

Click the  Info tool and click on the map to get information about a geographic area or district. A pop-up table shows data about the area that contains the point where you clicked.

Click on a record and additional data will display in the lower table. Percentage calculations for selected fields are displayed in the last rows of the table.

For thematic maps displaying census variables, SF1 data (100% population count) displays in the top section of the lower table. Further down, just after OccHU_Rent_Avg HH Size, a marker row -- SF3_SOCIO_ECON DATA --  demarcates  socio-economic data derived from the SF3 sample dataset.

  Zoom In tool:

Click the Zoom In tool and click on the map or drag diagonally and click to zoom in on a particular area. As you zoom in, more detail is added to the map (places, highways, water features, and streets). Multi-county applications are generally preset with a 4 to 1 zoom-in factor. Single-county applications are preset with a 2 to 1 factor. Use this tool with the scale bar (see below) to set the desired scale.
Zoom Out tool:

Click the Zoom Out tool and click on the map or drag diagonally and click to zoom out. The preset zoom-out factor is identical to the zoom-in factor. (see above)
Pan  tool:

Click the Pan tool and drag the map to reset the center and display a new area. For more precise directional shifts use the Pan buttons. (see below)

Similar to panning, the arrow buttons on your browser allow you to quickly scroll back and forth from previous map views using the browser's cache

Using the Map Buttons: The map buttons and links are located to the left of the map and function without a follow-up click on the map.

Find button:

Brings up a separate pop-up window where you can enter information on two forms as follows:

To Find Do This
An address Type the street address (street number required) in the Street Address box, the city in the City box, the ZIP Code (optional) in the ZIP Code box, the state abbreviation in the State Box (postal service)  and click Find. The map zooms to the address. Include the zip code for faster results. Intersections such as 1st and Main will often work. Rural Route numbers will not work.  If an exact address match is not found, the software will make a best guess based on the street numbering scheme. Omit the address to zoom map to a city or ZIP code.
A city, place, or county Type the city name in the City box and click Find. The map zooms to the city. Occasionally there are duplicate place names within a state. You will need to specify a zip code if  the map zooms to the wrong place. There are over 170,000 place names in this database --  including counties, municipios, parishes, cities, towns, subdivisions, and historical sites. 
A state Type the two-letter postal abbreviation in the State box and click Find. The map displays the entire state.
A ZIP Code Type the five-digit ZIP Code in the ZIP Code box and click Find. The map zooms to the chosen ZIP Code.
A specific block group or other geographic area. In the second form, enter the FIPS code for a census block group, i.e. State + County + Tract + Block Group.  The map zooms to the block group. Multiple groups (up to 100) are displayed for queries that match partial FIPS codes, e.g. State + County + Tract. FairVote2020 GOTV maps are generally set to search for precinct names. In some instances,  we have appended a county name as a prefix to allow for multiple precinct searches.
  A table with selected demographic data displays below the map. You can select and copy the table to a spreadsheet or document. The block group field (or other base geographic layer field) will remain "mappable" as a hyperlink.

For address-level searches, the map zooms to the full extent of the block group, or base geographic level. In rural areas with geographically large block groups,  you may need to use the ZOOM IN tool to display street-level detail. For place-level searches, the map is pre-set to zoom to a scale of 10 miles. You may need to use the ZOOM OUT tool or the scale bar to view the full extent of the county or municipality.

Directional  buttons:

Click on a directional button to pan the map in that direction.
Use the Pan tool (see above) to move across territory more quickly.
See All button:

Returns the map to the initial zoomed out scale. The default map is displayed.


Compare Maps

Compare Maps  list:

Select to view other maps identified in a drop down list. Redraws the map to display the plan or map selected. This feature is implemented upon request.

Zoom to an area of interest and toggle between maps. Then, using the arrow buttons on your browser, scroll back and forth to dynamically compare and contrast.

Current Scale
Scale bar :

Click the scale bar to progressively zoom from birds-eye (top) to street-level (bottom). Most maps are set to scale from 1 to 50 miles.
The width of the map (in miles) is recalculated at the top of the scale bar whenever the map scale changes. Use this button with the Zoom tools  (see above) to set the desired scale.

Additional Tips: To maximize the viewable area,  toggle off the history folder.  Map links can be e-mailed or bookmarked for future reference (If necessary, click refresh on browser to display a linked or bookmarked map. Select Zoom To and click on the area of interest to refresh the table).

Make sure your browser's cache has sufficient space to avoid time-consuming duplicate requests to the server software. The arrow buttons on your browser allow you to quickly scroll back and forth from previous map views using the browser's cache.

On most computers, all maps and data tables produced during a session are available for offline review (until the cache is cleared). Check the browser's history folder for pages visited at

Try Windows NetMeeting for group sessions.

Using the Display Boxes: The display boxes are located at the bottom of the map and can be toggled off and on by clicking on the boxes



Display: Census Place (2000) Interstate Highway Highway Community Sites Markers Streets  Redraw

The display boxes indicate the layers (streets, etc.) in the map that can be turned off and on.  Layers can only be turned off and on when the scale of the map falls within a pre-defined range (for streets, about five miles). Generally, layers are preset to display  (i.e., the display boxes are checked). To hide or drop a layer from the map, click the box to the left of the layer name, so that the check mark is removed. Then click the Redraw button to refresh the map with the new layer settings.

Maps display faster when there are fewer layers turned on.

Google-FairData Base Map : Available with many maps, icons linking to a Google map are located beneath the display boxes.

Opens a Google base map at a predefined zoom level on the center point of the map view.

Interactive maps produced prior to October 2005 may not include the Google map interface option. Upon request, this feature can be activated in any FairData interactive map.

See GMap Help for additional details.



If you use the interactive map frequently or wish to open two or more maps at once, configure Internet Explorer to check for new versions of stored pages. This will ensure that maps are properly updated when you pan or zoom, but slows things down a bit and is generally unnecessary.

  1. Open Internet Explorer.
  2. Select Internet Options from the Tools menu.
  3. Select the General tab.
  4. Click Settings in Temporary Internet files.
  5. Select Every visit to the page for Check for newer versions of stored pages.
  6. Click OK.

Interactive redistricting maps produced prior to October 2002 do not include the Pan tool or Display box features. These features can be activated upon request.
