The visualization shows cumulative and daily cases and deaths by urbanization level based on the 2013 National Center for Health Statistics (NCHS) urban-rural scheme, which categorizes U.S. counties into six-levels: (1) large central metro counties in metropolitan statistical areas (MSA) of 1 million or more population that contain the entire population of the largest principal city of the MSA, or are entirely contained within the largest principal city of the MSA, or contain at least 250,000 inhabitants of any principal city of the MSA; (2) large fringe metro counties in MSAs of 1 million or more population that do not qualify as large central metro counties; (3) medium metro counties in MSAs of 250,000–999,999 population; (4) small metro counties in MSAs of less than 250,000 population; (5) micropolitan counties in micropolitan statistical areas; and (6) non-core counties, non-metropolitan counties that do not qualify as micropolitan.
Daily cases and deaths numbers are calculated using a simple difference between consecutive days and smoothed using a 7-day moving average. Data are acquired from state level data made publicly available by the New York Times
and the Johns Hopkins University Center For Systems Science and Engineering
Note: Florida stopped reporting county-level deaths in June 2021. We have estimated daily county-level deaths after June 4, 2021 by apportioning daily total state deaths to each by county based on their share of COVID-19 cases 14 days prior.
