Jackson Parish, Louisiana air quality history
Daily Air Quality Index summaries from EPA monitors in Jackson, Louisiana, 1993–1995.
In 1995, EPA reported a daily Air Quality Index (AQI) for Jackson, Louisiana on 25 days. 24 of those days (96%) were in the Good range, and the median daily AQI was 15. That median is lower than the typical monitored county in Louisiana (median 37 across 21 counties), and lower than the typical monitored U.S. county (39). The main pollutant was coarse particles (PM10) on 25 days.
EPA did not report an AQI for every day of 1995 here (25 of 365 days). Figures describe monitored days only; seasonal monitoring (for example, ozone measured only in warmer months) can make a county look cleaner or dirtier than a full-year record would.
The most recent year with data for this county is 1995; EPA's files for 1996–2025 contain no row for it, which usually means its monitors stopped reporting.
Years with fewer than 120 monitored days (1993, 1994, 1995) are shown in the table but left out of comparisons and trend statements.

Typical and high-end AQI over time
The median is the middle day of the year. The 90th percentile is the level that only the highest 10% of days exceeded.

What this data can and can’t tell you
It is a county-level summary. EPA reports one AQI per day for the county, based on the monitors operating there. Air at a particular street, school or home can differ, especially near roads, industry or wildfire smoke.
It is not a health assessment. The AQI is EPA’s scale for communicating daily air quality. A county’s history can’t tell you what the health risk is for any particular person. For daily conditions and health guidance, see AirNow.
Rules change over time. EPA has revised AQI breakpoints, most recently for fine particles in 2024, so some year-to-year change can reflect the scale rather than the air.
