About the data

Demographics
  • Urbanicity: this categorization describes the county’s size, population density, and access to health care services. Source: Colorado Rural Health Center.
A note on the classification scheme from the Colorado Rural Health Center: all counties that are not designated as parts of Metropolitan Areas (MAs) are considered rural. The Colorado Rural Health Center frequently assumes this designation, as well as further classifies frontier counties as those counties with a population density of six or fewer persons per square mile.
  • Percent minority: the percent of the population that identifies as being Hispanic/Latino or a race other than white/Caucasian. Source: State Demography Office, Colorado Department of Local Affairs.
  • Median household income: a metric for the general socioeconomic status of the county. Source: 2013-2017 American Community Survey 5-Year Estimates.
Water
  • This section shows the number of public water systems in each county, the number of systems with at least one water sample of the regulatory limit for any contaminant, and the countywide average level of each contaminant. These countywide averages are weighted by the size of the population served by each water system. They are then depicted as being either over or under the regulatory limit set by the Environmental Protection Agency.
  • The bottom section shows the number of private well permits as well as testing results. Please note that wells are tested voluntarily.

Hospitalization and Emergency Department Visit Rates
  • This section shows the age-adjusted hospitalization and emergency department visit rates per 100,000 people for five health conditions: asthma, carbon monoxide poisoning, chronic obstructive pulmonary disease (COPD), heart attack, and heat-related illness.
  • Source: Colorado Hospital Association.
Climate
  • Maximum temperature by month is plotted alongside the percent of the county considered to be in severe drought each month. Possible impacts of this level of drought include crop or pasture losses, water shortages, and water restrictions.
  • Source: NOAA National Centers for Environmental Information, United States Drought Monitor.
Lead Risk
  • The lead risk and childhood lead testing section contain summary measures of the CDPHE Targeted Lead Outreach Tool. Information and methodology can be found at www.colorado.gov/cdphe/lead-outreach-tool.
