Legislative Mapper

FairData has developed an interactive map showing child poverty rates by current state legislative districts. Additional legislative district maps show other socio-economic data from the 2000 census, as well as party affiliation as of January 2007.

Change maps by clicking the drop-down menu under "Compare Maps" to the left of the map image. Click on the INFO tool and then click on the map to retrieve census data for the various geographic layers in a pop-up window. Or click on ZOOM TO and then click on the map -- summary data for the district selected will appear in a table below the map.

To display congressional boundaries, streets, etc., you must check the relevant display box below the map image, then click the Redraw button.

Note that in several states -- Arizona, Idaho, New Jersey, Nebraska (unicameral), Washington, District of Columbia (wards), and North Dakota -- upper chamber boundaries are the same as the lower chamber.

A 2006 court-ordered modification to Senate and House Districts 21, 26, and 27 in South Dakota is not reflected in the maps. (The plan was drafted by FairPlan for a Sec. 2 lawsuit)

Map 6 -- Sec. 203 Language Map -- (Voting Rights Act language minority 18+)

This thematic map shows voting age non-English speakers who do not speak English "very well". This category includes all non-English speakers 18 and over who speak English "well", "not well", or "not at all".

Map 7 -- Party Affiliation of Incumbent (2007)

Note: Incumbent and party affiliation data are from early 2007. There are nearly 7,500 legislators nationwide, so changes occur every month. Party affiliation is more stable than the name of incumbent.

This map does not display election returns below the county level.
