The American Lung Association (ALA) State of the Air 2018 report looks at levels of ozone and particle pollution found in official monitoring sites across the United States in 2014, 2015 and 2016. The report uses the most current quality-assured nationwide data available for these analyses. The report examines particle pollution (PM2.5) in two separate ways: averaged year-round (annual average) and over short-term levels (24-hour). For both ozone and short-term particle pollution, the analysis uses a weighted average number of days that allows recognition of places with higher levels of pollution. For the year-round particle pollution rankings, the report uses averages calculated and reported by the U.S. Environmental Protection Agency (EPA). For comparison, the "State of the Air 2017" report covered data from 2013, 2014 and 2015.

The only county in the North Coast Unified AQMD's jurisdiction that is able to receive a grade (i.e. there is monitoring data available) is Humboldt County.
