What the numbers say
Overview
Chittoor's AQI moved from 71 in 2022 to 76 in 2024 — a rise of 7.0% over 2 years. The long-run trend is worsening, with a regression slope of 2.5 AQI points per year.
The data story
The worst recorded year in Chittoor was 2024 at AQI 76, while the best was 2023 at AQI 68. The city has posted 0.7% of all measured days above AQI 200 (the Poor threshold), and its worst recorded single day hit 348 on 13 Nov 2023.
Why this pattern
A worsening trend in Chittoor typically reflects rapid urbanisation, vehicle fleet growth outpacing Bharat Stage VI emission benefits, expanding industrial activity, and in some cases new construction dust. The data points the finger at what policy needs to target next: year-round baseline emissions, not just the winter peak.
What to do with this
For planners and residents, the trend matters as much as today's number. A worsening city needs aggressive source control and personal protection investments like indoor purifiers. An improving city rewards continued policy pressure but still requires caution during peak months. Use the live AQI page for day-to-day decisions and this chart for multi-year context. Year-over-year change of more than 10% in either direction is typically real signal, not noise.
