Chicago Progressive Ideology Map

Understanding the Ideology Score

This map shows progressive ideology scores for each Chicago precinct, controlling for racial demographics and urbanist factors (renter %, transit use).

What the Colors Mean:

How to Read the Score:

Key Insight: This ideology score is what remains AFTER we account for race, renter status, and transit use. It represents the "true" progressive vs. conservative lean independent of demographics.

Limitations: This is supposed to only be applied to mayoral races because that is all this is taking into account. 2019 was too messy in the first round and Lori dominated too much in the second round to have any insights. The population has moved around and the electorate has probably changed since 2015 though so some areas might be a little off. In particular I think downtown could be skewing too conservative and places near O'Hare and Mount Greenwood might not be showing up as conservative enough.It is also relative to the city. In any given political environment progressives could have factors that boost them or hurt them.

Notes: for modeshare statistics they won't add up to 100% because this is census data and they count work from home as a modeshare. Also since this is census data, this is only commute modeshare. No other trips are considered in this and I am not aware of any source that has that data on a granular enough level for it to translate to precincts.
