China · Urban PM2.5 Concentration (WHO)
32.12023
Unit: micrograms per cubic metre. Publisher measure: Concentrations of fine particulate matter (PM2.5).
Annual population-weighted PM2.5 concentration in urban areas, matching WHO SDG11.6.2 metadata; label urban scope explicitly.
Measurement basis: model-based estimate.
Displayed values are rounded, with extra precision when needed to keep a positive estimate positive. Downloads retain the full numeric estimate and the publisher's original display text separately.
A “<” sign means strictly below the stated number. Numeric readings and uncertainty endpoints keep their own comparison signs. A number without a sign does not establish certainty or an observed outcome.

Download this immutable source capture · Source and coverage corrections
One row per country, indicator and year, with raw values, source links and reuse notices. Thresholds have an empty numeric value and separate number/operator fields; value_kind distinguishes upper bounds from absent readings.
History and uncertainty
Charts plot numeric readings. Reported upper bounds create gaps; their values, uncertainty endpoints and source notes remain available in the table and downloads.
Reported estimates and uncertainty · 14 rows
Each comparison sign applies to its own reading or uncertainty endpoint. Values retain source precision. “Not reported” identifies an absent reading or uncertainty endpoint in this source capture.
