How can I use Justice Map?
  1. Visualize race and income data for your neighborhood, county, state, or the entire US.
  2. Share a custom map with your friends.
  3. Journalists, bloggers, activists, and others can create maps for their online or print publications.
  4. Map makers can add race and income layers to their maps.
  5. Spatial Analysis. Advanced mode lets you compare who lives within 1 vs 5 miles of a location (and more!).

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 latest American Community Survey (five year summary).

How did you create the map?
We imported the census data into a postgis database and generated the tiles with TileMill.

Who is behind this project?
The website was developed by Aaron Kreider - as a project for Energy Justice Network and Sunlight Foundation. Further development has been supported by the Energy Justice Network and Aaron Kreider (volunteer hours).

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!


Updates
Aug 30, 2018. Redesigned the user interface to support mobile phones.

Jan. 9, 2018. We updated the income data from the 2011-2015 American Community Survey to the 2012-2016 data. This applies to tile layers, clicking on the map, and the API. This time Puerto Rico is included in the update!

Dec. 30, 2016. Try the Spatial Justice Test. It's a tool to identify environmental injustice (and more). You can test how race and income varies at different distances from a set of points. Use our power plant data or upload your own!

Dec. 20, 2016. We added a visualization that estimates Income at the Block Level. It can be used as an index that combines race and income to give a micro-level view of environmental injustice (or other forms of spatial injustice).

Dec. 13, 2016. We updated the income data from the 2010-2014 American Community Survey to the 2011-2015 data. This applies to tile layers, clicking on the map, and the API. Puerto Rico is still using the old data (2007-2011).

Race Layers
We have several race data layers that come from the US 2010 census. The Census Bureau uses two main variables - 'race' and 'hispanic'.


Income Layers
We use Median Household Income from the American Community Survey 2012-2016 five year summary These income values are estimated and we show the 90% confidence interval when you click on the map. Income data is only available at the county and census tract levels.


Density Layers
We use the Census 2010 data to calculate population density per square mile. This is available at the county, tract, and block level.


Geographical Resolution
We use four geographical units that come from the Census Bureau.


Analysis
Compare the demographics of several areas. You could test if people of a certain income or race are more likely to be near a location (ex. the site of a proposed waste facility or park). When you have this featured turned on, it returns the demographics for the area that you last clicked on and compares it to an area within x miles of it. That radius is chosen based on the map zoom level. You can add your own radius (in miles). You can remove a radius.
