The larger the score the more sustainable a city is compared with other US cities. City scores were ranked against all cities in the US (Overall rank) and those within their population group. The population groups are 1-10K, 10-25K, 25-50K, 50-100K, and 100K+.

Prescott, AZ had an average population of 45,122 people in 2021 according to the US Census Bureau.

Cities with a higher score have better air quality. Data based on 2018-2023 average air quality index.

The air quality sector is 10% of the final index.

Air Quality Index (AQI) through time, larger values (darker red/orange) is more polluted air. Missing data for previous years assumed to equal the first year of data availability. We collected annual average AQI data from IQAir, which measures the density of particulate matter less than or equal to 2.5 micrometers in the air (PM2.5). AQI ranges from 0 to 500, but a healthy AQI is 0 to 5 PM2.5 (lower the better).

We use the US Environmental Protection Agency’s estimate of the proportion of the population with access to public transit. The more people who can get around the city by public transit the higher the score and more sustainable the city. The EPA's transit coverage is limited to metro areas served by transit agencies that provide their data in a GTFS format, as a result the data leans towards US cities with a university. We plan to add TransitScore data soon to improve this sector.

The public transit sector is 20% of the final index.

Cities with a higher score support more reuse businesses, use their local library more, or have more Little Free Libraries than other US cities. Data points pulled from Google maps and the Little Free Library website in June 2024. Point data per capita based on 2017-2021 average population, while library visits are based on their legal service area population.

The reuse sector is 5% of the final index.

Library visits and Little Free Libraries per person. Darker green/blue is more sustainable because of higher reuse of community items. Find out how you can track your Little Free Library book use here.

Cities with a higher score used less energy per person compared to other US cities. Data from a 2019 city energy survey and the 2012-2016 average population. We chose eight features to include: residential, commercial, and industrial electricity and natural gas consumption (6 features), as well as on road consumption of gasoline and diesel (2 features).

The energy sector is 40% of the final index.

Electricity (MWh) and natural gas (MCF) used per person across residential, commercial, and industrial areas of the city. More energy consumption per person (darker red/orange) is less sustainable.

Gasoline and diesel (gallons) used per person. Higher consumption (darker red/orange) is less sustainable.
