Findings come from a fixed rule table and a fixed sentence per rule. There is no model in this path: the numbers are detected, ordered and worded by code, and every one of them prints the operation that produced it.

What these numbers are not

  • A percentile here is a min-max scaling of average rank across the entities that published the metric this period: the smallest published value scores 0 and the largest scores 100. It is not the share of entities below the value, and entities that did not publish the metric are counted in neither the rank nor its denominator.
  • The named indicators shown beside this brief are national or basin-level series, not measurements of Mason County, IL; 30-year fixed mortgage rate (watch), Los Angeles + Long Beach container volume, annual (watch), Shanghai to Los Angeles container rate (watch) and WTI crude oil, spot (watch) are at a watch or alert level. They are context.
  • Water rows are everything within 75 km of this place's internal point (150 km for reservoirs), not everything inside its boundary: lib/water searches discs, and every row prints its own distance.
  • Server report: satellite turbidity is only computed in a browser, so that term is absent here.
  • USGS gauges did not answer.
  • USGS wells did not answer.
  • Stress uses 1 of 4 terms (drought); missing terms are left out, not assumed.
  • Groundwater has no trend term: one latest level cannot say whether an aquifer is being drawn down.
  • BLS QCEW did not answer; no per-job figure.
  • Obligations are what agencies committed in FY2026 by place of performance: not outlays, and not the recipient's own location.
  • FY2026 closed 24 days ago; agencies report with up to a 45-day lag, so totals are still filling in.
  • The indicator block is the NATIONAL set, filtered only by lens. None of these series is keyed to this place: they are United States, gauge, single-state or port series and they are shown as context, not as this place's own readings.
