Context
PrEPárate was a social marketing campaign promoting pre-exposure prophylaxis (PrEP) treatments to prevent HIV infections among the Latine communities in the Chicagoland area. The campaign was released online— through a website and social media accounts of partner community organizations besides our own—, a hotline, and ads vehiculated on bus and train routes of the Southwest areas of Chicago, where most of the Latine community is located.
Problem
We needed to know our priority areas in the city of Chicago for the social marketing campaign, so we could vehiculate the right ads. Two variables were the most important: neighborhoods with the highest HIV incidence rates, and neighborhoods with the highest proportion of Latine population.
Unfortunately, it can be challenging to represent two variables simultaneously in a map.
Solution
I represented different HIV incidence rates by community area with a color scheme (a method also known as a choropleth map).
Then, I filtered the Chicago community areas with 30% or more of Latine population.
Results
We successfully vehiculated the campaign with the collaboration of our community partners and the Chicago Transit Authority. In the campaign, we focused on Southwest neighborhoods of Chicago, which were previously identified in my maps.
