In the 1930s, the federal government drew red lines on maps of Denver and deemed certain parts of the city "hazardous," or "definitely declining." People in those neighborhoods, like Five Points and the Highlands, were denied mortgages to buy homes.
 
The practice discriminated against communities of African Americans, Latinos and immigrants. The impact of that racism is still felt today. Megan Arellano and Erica Meltzer are reporters at Denverite. They've recently looked into how redlining is now contributing to gentrification in the city. 

​Arellano and Meltzer spoke with Colorado Matters host Ryan Warner.
