What these numbers are not

  • The newest BLS QCEW file carries no year-earlier level, only the over-the-year percent change BLS publishes itself. Every employment and wage comparison here states that published change; none of them is a move from one level to another, because the two levels are not both in the file.
  • 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 San Mateo County, CA; 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.
  • The occupation mix is the 41860 metro area's, from the bundled BLS OEWS release: OEWS does not publish a county table.
  • 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.
  • USAspending did not answer for recipients, awarding agencies and NAICS.
  • Obligations are what agencies committed in FY2026 by place of performance: not outlays, and not the recipient's own location.
  • FY2026 closed 19 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.
