Community Explorer and COVID-19


The COVID-19 Community Explorer provides a simple way to explore geographic clusters of county-communities affected by the pandemic and their socioeconomic, demographic, and health-related features. More specifically, it clusters 751 variables (behavioral, demographic, economic, and social factors) for 3142 counties into 17 population profiles using machine learning techniques.

These profiles can be summarized as follows:

Mainstream America captures 74% of the U.S. population spread across 819 urban core, suburban, and small metro counties.
1-Urban-Core => Prosperous, ethnically and linguistically diverse large metro areas with substantial disparities between their highly educated (largely White ) and less educated (largely Black or African American) residents (26% of the population)
2-Lower-middle Class => Less populous suburban and small metro counties that are not as economically prosperous as the rest of Mainstream America (18% of the population)
3-Affluent Suburbs => Affluent and more populous (but less diverse) suburban and small metro counties that jointly represent the profile with the highest median income (16% of the population)
4-Middle Class => Middle-class communities with a largely White population that resides in large- to medium-sized suburban and small metro counties (14% of the population)

Industry-driven America captures 17% of the U.S. population spread across 1507 counties in which employment is concentrated in one industry that shapes all aspects of the population's profile.
5-College Towns => College towns with a relatively young, highly educated, and highly geographically mobile population (5.4% of the population)
6-Manufacturing Midwest => Counties primarily located in the Midwest that form the profile with the highest proportion of White population working in the manufacturing sector (5.2% of the population)
7-Low-wage Manufacturing => Low-wage workers in the manufacturing and chemical industries located largely in the South and North-East regions of the country, with an above-average proportion of the population living below the poverty line (4.9% of the population)
11-Hispanic Agriculture => Highly agricultural communities with a higher than average concentration of Hispanic or Latino population residing mostly in the West and South (1.2% of the population)
15-The Great Plains => => Agricultural counties located in the Great Plains with a high proportion of the White population (0.3% of the population)

Graying America captures 5.1% of the U.S. population spread across 424 counties that jointly represent the highest concentration of population of age 65 years or older.
8-Retiree Communities => Retiree communities with adequate household incomes and access to economic resources (4.5% of the population)
13-Isolated Seniors => Isolated seniors with high disability rates and relatively low incomes (0.6% of the population)

9-Hispanic Southern Border => Counties mostly located along the U.S. southern border with a majority of a relatively young Hispanic or Latino population living in extreme poverty (1.4% of the population)
10-Black South => Southern counties with the highest proportion of Black or African American population and lowest median household income of all profiles (1.3% of the population)
12-White Appalachia => White communities in Appalachia with the third-highest level of unemployment rates and second-lowest household income of all profiles (0.7% of the U.S. population)
16-American Indian Reservations => American Indian Reservation communities living in extreme poverty with more than one-third of the population with income below the poverty line (0.1% of the population)

Noncontiguous America captures 0.42% of the U.S. population spread across 14 counties that combine all Hawaiian and nine Alaskan counties.
14-Hawaii => The Aloha State with high racial and ethnic diversity, high income, and relatively low-income inequality (0.4% of the population)
17-Native Alaskan => Alaskan communities with large economic gaps between the White and Alaska Native populations (0.02% of the population)
