Sources and interpretation
Data come from the authenticated county registry and U.S. Census Bureau ACS five-year surveys or Population Estimates Program as identified in the selected contract. Missing, suppressed, ineligible and incompatible observations are excluded, never converted to zero. Counts below a population threshold are distinct from unavailable observations.
ACS margins of error, when available, are 90% confidence margins. Small differences in ranks may not be statistically meaningful. PEP estimates do not have ACS sampling margins. These rankings do not measure safety or desirability.
