Hegewisch vandalism is the lead signal for March 2026 — a sharp move above its multi-year baseline, the most prominent fresh signal in a month that otherwise skews toward sustained declines. There is no recurring lead from prior months to displace; this is a clean new story at the top of the rankings.

Citywide volume is down 8.6% against the prior 12 months — 130,075 incidents against 142,267 the year before. The signal mix is weighted heavily toward structural improvement: 69 sustained-shift signals and 29 below-trend moves against 14 fresh spikes across 77 neighborhoods. Armour Square sexual assault and Gage Park other-larceny both registered spikes in the top five, pulling in two separate categories alongside the Hegewisch vandalism lead.

With 114 total signals and a clear downward trend in volume, March reads as a continuation of the multi-month decline rather than a reversal. The fresh spikes in Hegewisch and Armour Square are worth tracking in April — one month of movement in a low-base neighborhood is not yet a pattern, but both categories appeared in more than one neighborhood this period.

Lake-fronting flat city laid out on a strict grid; the 77 community areas were defined by the University of Chicago in the 1920s and remain the city's standard analytical unit. Major arterials (Lake Shore Dr, Western, Western Ave, the I-90/94 expressway) define most community-area boundaries.

ACS 2023 5-year estimates, county-level (Cook County). Cook County is broader than Chicago city — county-level medians (rent, home value, household income, age) lean slightly different from a Chicago-city-only median. Per-tract counts (population, households, housing units) sum only the ~790 tracts that fall inside the city.

Walk score77 (very walkable)

Dense, transit-rich core (Loop, Near North, Lakeview) gives way to mid-density bungalow belts and lower-density South and West Side neighborhoods. The CTA L network shapes most North Side and West Side travel patterns; far South Side is more car-dependent.

Open data lag≈ 7 days (settled)

CPD started submitting to NIBRS in 2021 but the public Crimes dataset has stayed on the IUCR coding scheme for stability. Our category mapper translates IUCR primary types and descriptions into the same UCR Part 1 buckets used elsewhere on the site, so cross-city comparisons stay apples-to-apples. The dataset documents a 7-day reporting buffer.

Methodology

Every signal, every forecast, documented

Open about how we define spikes, what we exclude as noise, where the data comes from, and how often the model is wrong.

# anomaly rule — spike
flag = (z >= 2.5) AND (current_12mo >= 20) AND (current_6mo above sustained band)
where z = (current_12mo − μ_baseline) / σ_baseline
# exclusions (excerpt)
· simple assault (varies by reporting practice)
· drug offenses (reflect policing policy)
· admin records, weapons-possession, fraud
