Chicago Lawn Crime Rate Trends — Chicago
Chicago Lawn — also known as Marquette Park — is a Southwest Side neighborhood organized around 63rd Street and California Avenue. Anchored by Marquette Park itself, one of the largest parks on the South Side, with predominantly bungalow housing on a tight grid.
Three categories moved in Chicago Lawn this June — two one-month below-trend signals and one sustained structural shift. The shape of the month is broadly downward, with both property crime and violent crime running below recent norms, and robbery showing a multi-month structural decline rather than a single quiet month.
Vandalism's trailing 12-month total is 505 incidents against a baseline of 631.42, the most prominent single-month below-trend signal. Robbery reinforces that picture from two angles: a one-month drop and a sustained shift — the 12-month count is 105 against 177 the prior year, a 40.7% decline. Everything else, including aggravated assault at -17.2% year-over-year, fell within the broader downward pattern; motor vehicle theft and sexual assault were the only categories running above prior-year levels.
Notable signals 2
Vandalism
The past 12 months saw 505 incidents — about 20% below the 631 average from prior years.
Robbery
The past 12 months saw 105 incidents — about 48% below the 204 average from prior years.
All categories, last 24 months
Each panel: recent monthly count vs. trailing 12-month context. MoM is the most recent month vs. the one before; 12mo YoY compares the trailing year to the year before that.
What's been quietly true for a year
Spikes get attention. Sustained shifts shape policy. These are multi-quarter patterns where the past 12-month total differs meaningfully from the year before — they often precede the baseline resetting.
- Robbery has reset to a lower baseline.
The trailing 12-month count is 105, down 41% from 177 the year before. If the trend holds another quarter, it will pull the multi-year baseline down.
What next month likely looks like
Forecasts trained through June 2026, with a likely range we're 95% confident the actual count will fall inside. Categories with too little recent volume — or violent categories at the neighborhood level — show no forecast and are surfaced through signals above instead. See the methodology page for the gating rules.
Aggravated Assault
Too low-volume per neighborhood for a reliable point forecast — see the rare-event and streak-break signals above instead.
Arson
Below the volume threshold for a reliable forecast — too few incidents in recent months to project from.
Burglary
Homicide
Too low-volume per neighborhood for a reliable point forecast — see the rare-event and streak-break signals above instead.
Motor Vehicle Theft
Other Larceny
Robbery
Too low-volume per neighborhood for a reliable point forecast — see the rare-event and streak-break signals above instead.
Sexual Assault
Too low-volume per neighborhood for a reliable point forecast — see the rare-event and streak-break signals above instead.
Vandalism
How Chicago Lawn compares
Peer neighborhoods picked by closest 12-month vandalism volume — a pragmatic v1 of peer matching. Demographic / housing-stock peer matching isn't built yet (we deliberately don't ingest income or race data alongside crime). Volume similarity has the right intuition: “neighborhoods experiencing comparable vandalism levels.”
Englewood
509 incidents over the past 12 months — 4 above Chicago Lawn's 505.

Top terms in incident descriptions for Chicago Lawn, excluding generic crime taxonomy. Useful as texture — what kinds of specifics show up here that don't show up elsewhere.
Hour-of-day, day-of-week, and seasonality
Distribution of bucketed incidents in this neighborhood across the full analysis window. Useful for routine context — shopping-strip thefts vs. late-night assaults read very differently when you can see when each typically happens.
How we built this page
Data → Anomalies → Forecast → Page
Incident data is pulled from CPD's open dataset on the City of Chicago Open Data portal — IUCR-coded and mapped to 9 UCR-aligned categories (theft from vehicle isn't reliably separable in the public feed and rolls into other larceny). Aggregated to community area × category × month.Anomalies are surfaced using strict thresholds (~p < 0.01). Forecasts are Prophet with low-count gating; violent categories at the neighborhood level skip the forecast and show rare-event / streak signals instead.
Spike rule: 12-mo total > baseline mean + 2.5σ AND ≥ 20 incidents AND 6-mo confirms. Drop rule: 12-mo total < baseline mean − 2.5σ AND baseline mean ≥ 20. Rare event: any incident in the last 90 days, no prior comparable in ≥ 5 years.
