Short Sleep Duration by County — US Rankings
CDC PLACES 2023 · Age-adjusted prevalence · All 3,144 US counties
Short sleep is the share of adults reporting fewer than seven hours per 24-hour period — the CDC threshold below which adverse cardiometabolic associations show up consistently in the research literature. PLACES age-adjusts the estimate. Short-sleep prevalence is notably high across the rural South and the urban Northeast, two very different geographies; shift work, commute time, and ambient noise are likely drivers but are not captured in the survey. This is a behavioral indicator, and like all self-report it understates the extremes.
How this ranking is built
Source: CDC PLACES 2023 release. Methodology: BRFSS survey responses pooled across years, fitted with a small-area statistical model, age-adjusted to the 2000 US standard population. Confidence intervals (95%) are shown for each county — wider intervals indicate more uncertainty in the modeled estimate, typically driven by smaller populations.

What this ranking suggests
Short sleep is one of the few risk-factor measures the CDC tracks at the county level that is essentially universal — every county has some prevalence. The rankings are most useful for spotting outliers (rural counties with unusually high or low prevalence) rather than as a clinical screening tool.
Methodology notes & limitations
Estimates are statistical model outputs, not direct measurements. Small counties have wider confidence intervals; treat narrow rank differences in those rows as within-noise. Counties where the underlying population is too small to support modeling are suppressed entirely (about 1% of US counties). All measures are age-adjusted to the 2000 US standard population. The PLACES dataset uses BRFSS self-reported data — self-report introduces known direction-of-bias in some measures (BMI is under-reported; binge drinking is under-reported), but the bias is roughly uniform across counties so ranking comparability is preserved. See the methodology page for full data-pipeline documentation.
