Share of 339 monitored prefecture-level cities meeting the national air-quality standard; 2025 prelim.
In 2025, 72.6% of China’s 339 monitored prefecture-level cities met the national air-quality standard. The complementary share that did not meet the standard was 27.4%. The published percentage is rounded rather than an exact compliant-city count. The graphic therefore shows shares and the monitored-city universe without converting them into estimated city totals.
| Rank | Entry | Value | Period |

Dataset/table: Cities Meeting the National Air Quality Standard, 2025
Units: percent and cities
Date checked: 2026-07-18
Evidence: Supports the share of monitored cities meeting the air-quality standard and the 339-city monitoring universe.
The 72.6% share is rounded, so multiplying it by 339 would not produce a source-backed exact number of cities. The annual figure is preliminary.
The published compliant-city share is paired with its mathematical percentage complement for the stated 339-city universe.
The compliance share and monitored-city universe use the same official 2025 environment section.
