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
Jan. 14-16, 2020. We updated the income data to use the 2014-2018 American Community Survey.
Jan. 13, 2019. We updated the income data from the 2012-2016 American Community Survey to the 2013-2017 data. This applies to tile layers, clicking on the map,
and the API. Puerto Rico is included in the update! An even bigger change is that we updated the income categories (for the first time),
and started controlling for inflation in the Income Change layer.
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).
