Hegewisch: CRIMINAL DAMAGE — Crime reports

• Exploratory description, not a forecast, causal explanation or proof of a change.
• Approximate 95% factor intervals assume independent, constant-variance log residuals and fixed boundaries. They do not account for boundary search, serial dependence or source revisions.
• Confirmed zeros are treated as 1 only for fitting and its diagnostics. Raw counts stay zero; low-count results depend on this convention.
• Independent phase lines may jump at boundaries. Every observation belongs to exactly one phase.
• Reporting, classifications and seasonality can change. Counts are not population-adjusted; a level shift without a slope change is not the target of this search.
• Uses dated last-good cached data, not newly verified source counts.
• Many dependent filter conditions were searched. No multiple-testing-adjusted significance or causal attribution is claimed.
• Frequency compares fixed equal-length windows of raw counts, not population risk or a celeration-factor ratio. Reporting, classifications and exposure may have changed.

Intervals assume fixed boundaries and independent log residuals. They are not adjusted for the phase or filter search. Near-optimal boundary ranges are not confidence intervals.

Newest first. Unknown coverage is not a zero. These are the original saved observations, not fitted or rounded predictions.

Source note

Source ijzp-q8t2. Joint day/category/hour/applicable-flag/ward/status counts; no addresses, coordinates or incident identifiers. Each year's cells reconcile with an independent source total. Reads are not an atomic publisher snapshot. Published crime reports, not population-adjusted rates or final incidence. Prepared daily community-area snapshot; scheduled rebuild at 06:00 America/Chicago. Full supported history is rechecked for corrections. Retrieval timestamps are preserved; this is not a real-time feed. Crime analysis starts January 1, 2002; 2001 is excluded from counts and fitting inputs. Local indexed neighborhood snapshot. Totals are for the loaded area before other filters, not citywide totals. Citywide and unassigned-area views use a separate network-backed scope.
