Justice Map - open map tile layers for race and income powered by Census Data.
I want you to use the layers on your own map
April 16, 2015. We updated the income data from the 2007-2011 American Community Survey to the 2009-2013 data. This applies to tile layers, clicking on the map,
and the API. Puerto Rico is still using the old data.
How can I use Justice Map?
1) To visualize race and income data for their neighborhood, county, state, or the entire US.
2) To help journalists, bloggers, activists, and others create maps for their online or print publications.
3) To help map designers add race and income layers to their maps.
4) To allow for basic GIS data analysis. Advanced mode lets you compare who lives within 1 vs 5 miles of a location.
What data layers do you have?
We have several race layers and income layers (three different
representations of median household income). The race layers are available at the county, census tract, block group, and block level. The income layers
are available at the county and census tract level. This provides greater detail when you zoom in.
What are open map tile layers?
We have 100 GB of map tiles that we are sharing. Similar to open software anyone can use them on their website.
This saves map makers the time required to deal with large datasets and tile production.
What is the data source?
Our information comes from the Census Bureau - the 2010 Census and the 2009-2013 American Community Survey (or 2007-2011 for Puerto Rico).
How did you create the map?
We imported the census data into a postgis database, generated the tiles with TileMill (in mbtile format), and exported the mbtile into png using a python utility:
