About this term

Air quality index (AQI) ranges from 'Good' (0-50) to 'Hazardous' (401+), with intermediate categories. High AQI levels cause respiratory and cardiovascular health impacts, particularly affecting children and elderly residents. Neighborhoods with consistently poor air quality see reduced demand and lower property values. Industrial areas, highways, and pollution sources create localized air quality problems affecting property values and health.

Pro Tip

Check historical air quality data. Neighborhoods with recent improvements may offer value opportunity.

Example

A neighborhood with average AQI of 45 offers good air quality, while AQI over 150 indicates unhealthy pollution levels.
