South Shore Crime Rate Trends — Chicago
South Shore is a South Side lakefront neighborhood organized around 71st and 79th Streets, anchored by the South Shore Cultural Center (the former South Shore Country Club) and Rainbow Beach Park. Mixed mid-rise apartments and single-family homes, bordered by Lake Michigan to the east and the Metra Electric line to the west.
Three tracked signals surfaced in South Shore this August: two one-month below-trend signals and one sustained structural shift. The shape of the month is broadly downward across violent crime, with robbery and homicide both running below trend in the current period and robbery also showing a multi-month structural decline, not just a single quiet reading.
Robbery is the strongest signal, with the trailing 12 months at 191 incidents against 260 in the prior year, down 26.5%. Homicide is also below trend, at 11 incidents over the current 12 months compared to 29 in the year before, a drop of 62.1%. Aggravated assault is tracking lower as well, down 16.4% year-over-year, though it did not cross the anomaly threshold this month. On the other side of the ledger, motor vehicle theft is up 15.4%, vandalism up 10.0%, and arson up 28.6% on a small base, those categories were within range for anomaly thresholds but represent the countervailing pressure in the neighborhood's overall picture.
Notable signals 2
Robbery
The past 12 months saw 191 incidents — about 36% below the 299 average from prior years.
Homicide
The past 12 months saw 11 incidents — about 67% below the 33 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 191, down 27% from 260 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 August 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 South Shore compares
Peer neighborhoods picked by closest 12-month robbery 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 robbery levels.”
Near West Side
189 incidents over the past 12 months — 2 below South Shore's 191.

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.
