What three Massachusetts cities reported to 311 on their latest full day of data that was unusual for that day of the week, measured against each category’s own recent history.
Boston logged 51 requests under Fallen Tree or Branches on Saturday, about 12.8 times its usual level for the day. It arrives alongside Trees, a combination that usually points to wind or storm damage rather than 2 unrelated changes, and it spans Boston and Somerville. Separately, Unknown/Miscellaneous in Somerville at 3.2x. Cambridge ran normally.
A category is listed when it is at least 1.8× its own same-weekday average for the previous four weeks, with a Poisson z of 2.5 or more to rule out small-number noise. Ranked by how far from normal, not by raw volume.
These did not clear both thresholds. Most are high-volume categories where a statistically real rise is still a small relative change.
Each city has its own report, covering ninety days of volume, what moved on the latest day and the caveats specific to that feed.
Shown because these pipelines are new. If one stalls, a quiet day and a broken feed look identical unless the lag is on the page.
