What these figures mean

Federal money. Federal awards whose work was listed in this county for fiscal year 2025.
Weather alerts. Flood, wind, winter storm, and similar warnings for Maine from the weather service. Zero means none were in effect when we last checked.
Density. People divided by land square miles. Downtown Portland is dense; an unorganized township is not.
Land. Square miles of land, from the Census Gazetteer. Water is counted separately.
Income. American Community Survey 5-year estimate. Half of households earn more, half earn less.
EPA sites. Sites EPA tracks for air, water, or hazardous waste rules. A count is not a violation score.
Climate reporters. Factories, power plants, and landfills large enough that EPA makes them report greenhouse gases each year. Not every shop or farm — only the big ones. Latest complete year is 2023.
Chemical reporters. Workplaces that use certain chemicals and file a yearly Toxics Release Inventory form. A count is not the same as “this county is dirty.” It means those sites exist and have not been marked closed.
Housing. Houses, apartments, and other units, occupied or empty. ACS 5-year.
Median age. Half the people are older than this age, half younger. ACS 5-year.
