Scan evaluated November 9, 2026 · 116 qualifying candidates · 0 annual-only contexts · 46 frequency flags · 75 turn flags

What this measure can tell us

A change in reported crime can be a useful starting point for investigation, but the chart does not explain why it happened. These candidates describe published records grouped by recorded incident date and community area. The research scan excludes 2001 under the dashboard’s history policy, even though the source dataset’s title begins in 2001.

The single-filter search considered each named community, each crime category, arrest and domestic flags, and four six-hour bands. An arrest flag belongs to the published record; it is not a count of all arrests made in the neighborhood. Category changes, recording practices, delayed reports and later corrections can affect comparisons.

Read the two signals separately. A frequency candidate compares two full 12-month totals; a turn candidate compares the slopes of adjacent fitted phases on the same six-month scale. A series can qualify for a frequency change while the phase detector withholds its suggested turns because of serial pattern in the residuals. That is a limitation of the fitted explanation, not proof that the observations are stable.

Questions worth asking next

  • Does the pattern persist in the unfiltered community total?
  • Does a neighboring community or related category provide disconfirming evidence?
  • Could reporting delays, classification or record revisions explain the timing?

Except for explicitly documented case-study follow-ups, these are proposed checks, not completed investigations. The numerical screen cannot choose among causal explanations.
