Got a Ride? Ridesharing Equity in Chicago

I expected Uber and Lyft pickups to cluster in white, wealthy Chicago neighborhoods. 42 million trips later, the data said no — the pickups go where the trips are, which mostly means downtown.

The Question

Hypothesis
Rideshare access tracks
income and race

42M trips · 13 months
77 Community Areas
EPSG:4326

Uber and Lyft are now a meaningful share of Chicago's transit mix. Whether they reach the neighborhoods that need them is a separate question.

Guess: pickups skew toward wealthier, whiter community areas. The test set: 42 million anonymized rideshare trips from the City of Chicago's TNP dataset (every Uber, Lyft, and Via pickup, Oct 2020 – Nov 2021), joined against Census income and race data across all 77 Community Areas.

Pickups vs. Income

If pickups tracked income, the largest yellow dots would sit on the darkest-blue (highest-income) North Side tracts. They don't.

Pickups vs. Race

Northern lakefront and Near North Side hold the highest white population shares.

% NONWHITE
The South and West Sides — mostly nonwhite — still get plenty of pickups, especially near employment corridors.

Side by side, the maps don't track demographics. Downtown and the Near North Side dominate pickups whether you're looking at the income map or the race map — they dominate because that's where the trips originate, not because of who lives there.

The original Folium maps from the notebook. Click any bubble for its Community Area name and count.
Pickups. Bubble size = total rideshare pickups in that Community Area.
Median income. Bubble size = median household income.
% white. Bubble size = share of white residents. Notice it looks a lot like the income map.
All three. Pickups, income, and race on the same map. The pickup bubbles don't sit where the demographic bubbles sit.

Findings

  • Hypothesis: disproven. Pickup volume doesn't track income or share of white residents at the Community Area level. Whatever rideshare is doing in Chicago, it isn't quietly skewing toward whiter, richer neighborhoods.
  • High income can mean low demand. One of Chicago's highest-income areas had among the fewest pickups — those residents own cars and drive themselves.
  • Pickups follow trips, not people. The Loop, the Near North Side, and the big employment corridors dominate, full stop. That's where people actually need rides — regardless of who lives there.
  • Income and race are nearly the same map. The two choropleths are visual near-mirrors of each other in Chicago. Any single-variable equity test runs into that wall before it can say much.
