Small counties, wider variation
How does the spread of county life expectancy change with population size?
- County
- 5th–95th percentile, by population decile
CHR 2024 v147 (life expectancy, NVSS 2019–2021) against population (v051) for all ranked counties reporting both. Envelope: 5th and 95th percentiles of life expectancy within each population decile, plotted at the decile median population. The shaded range describes variation between counties; it is not a confidence band or a control limit. The population axis is logarithmic. Counties outside the envelope are not automatically errors.
