Make sure you're fairly represented when political districts are redrawn in 2021. You only get this chance every ten years after the census is completed, so don't be left out in the cold.
Some politicians try to draw districts so they can never lose. This gerrymandering lets them ignore the people they are supposed to represent. Draw a community of interest map to provide your input to the redistricting process in 2021 and fight gerrymandering.

What is a Community of Interest?
A community of interest (COI) is a population that shares cultural, historical, demographic, or economic interests. They do not necessarily share the same political viewpoints. Representable
Mapping communities of interest encourages the drawing of fairer voting districts. Community residents can help redistricting officials by mapping out the boundaries of local communities that should be kept together within a district. COI maps can often be presented to the redistricting body in public hearings along with petitions with data for the districts or boundaries presented. Courts may refer to community of interest maps for guidance if the redistricting process ends up in litigation.
Finding your community of interest
Decide what is in common between the people living in your community. This might be something cultural, historical or demographic. Use free data sources to see where people sharing those traits live in your community and then draw your community of interest map. DemLabs evaluated three different sources of information which can be used to understand where a community of interest is, before it is drawn. Two of the sources are free and the third is very affordable. We chose Harris County, Texas for this exercise and picked race and poverty level as the selection criteria.
These tools are also great resources for community organizers and canvassers by helping them better understand and locate the people they are serving.

RATF**CKED
RATF**CKED explains how a small group of Republican operatives rigged our American democracy through redistricting. Karl Rove, Ed Gillespie, and Chris Jankowski devised a way to take a tradition of dirty tricks - known to political insiders as "ratf**king" - to a whole new unprecedented level. Flooding state races with a gold rush of dark money made possible by Citizens United, the Republicans reshaped state legislatures, where the power to redistrict is held.
"The GOP poured money into an unprecedented effort to control governorships and state legislative bodies in 2010 and to then redraw congressional districts so that the party could turn the House into a firewall against the Democrats. The result is that House Republicans have become more dug into their opposition to every presidential initiative, playing to their very red districts, and there is nothing but gridlock on Capitol Hill. Bipartisan deals are impossible, and the chances for good governance have disappeared. Indeed, Republicans have been so successful that they have created an unanticipated problem: GOP incumbents now have to worry about primary challenges from tea party Republicans who want to move even further to the right." - Washington Post
