What it goes with
The strongest links that have a page of their own. Unadjusted is the link before adjusting for anything, from −1 (opposite) to +1 (in step). Adjusted compares places with the same population density, income and education levels, so those differences can’t explain the link. This list leaves out the 1 pairs built from the same numbers or the same model as this measure, since they are bound to match.
| Measure | Unadjusted | Adjusted |
|---|---|---|
| Flu vaccination among Medicare enrollees and Safety scoreLinked across counties, but mostly as both follow how urban, rich and educated a place is. Comparing only places with similar density, income and education, a weak link of +0.23 remains. Safety score by US county | +0.50 | +0.23 |
| Flu vaccination among Medicare enrollees and Motor vehicle crash deathsLinked across counties, but mostly as both follow how urban, rich and educated a place is. Comparing only places with similar density, income and education, a weak link of -0.22 remains. Motor vehicle crash deaths by US county | -0.57 | -0.22 |
| Flu vaccination among Medicare enrollees and Colorectal cancer screeningLinked across counties, but mostly as both follow how urban, rich and educated a place is. Comparing only places with similar density, income and education, a weak link of +0.22 remains. Colorectal cancer screening by US county | +0.51 | +0.22 |
| Flu vaccination among Medicare enrollees and Injury deathsPoints one way across counties (-0.14) and the other across people (+0.15), when bigger places count for more: the average county and the average resident disagree. Injury deaths by US county | -0.37 | -0.14 |
| Flu vaccination among Medicare enrollees and Share of some other race, not HispanicLinked across counties, but mostly as both follow how urban, rich and educated a place is. Comparing only places with similar density, income and education, what is left could easily be chance. Share of some other race, not Hispanic by US county | +0.50 | -0.10 |
| Flu vaccination among Medicare enrollees and Cholesterol screeningLinked across counties, but mostly as both follow how urban, rich and educated a place is. Comparing only places with similar density, income and education, what is left could easily be chance. Cholesterol screening by US county | +0.52 | +0.08 |
Population makeup
How this measure varies with the racial and ethnic makeup of counties. Every group is shown, whatever its rank. These are links across counties: they describe places, not people. They say nothing about any person’s risk or behaviour based on their race. Counties with a larger share of one group also differ in much else, such as income, segregation, region and history. The adjusted figure only accounts for density, income and education.
| Share of residents | Unadjusted | Adjusted |
|---|---|---|
| Flu vaccination among Medicare enrollees and Share White, not HispanicWhere Flu vaccination among Medicare enrollees is higher, Share White, not Hispanic tends to be higher: a weak link that holds when only places with similar density, income and education are compared. Share White, not Hispanic by US county | +0.10 | +0.25 |
| Flu vaccination among Medicare enrollees and Share Black, not HispanicWhere Flu vaccination among Medicare enrollees is higher, Share Black, not Hispanic tends to be lower: a weak link that holds when only places with similar density, income and education are compared. Share Black, not Hispanic by US county | -0.11 | -0.13 |
| Flu vaccination among Medicare enrollees and Share Hispanic or Latino, any raceWhere Flu vaccination among Medicare enrollees is higher, Share Hispanic or Latino, any race tends to be lower: a weak link that holds when only places with similar density, income and education are compared. Share Hispanic or Latino, any race by US county | -0.19 | -0.23 |
| Flu vaccination among Medicare enrollees and Share Asian, not HispanicWhere Flu vaccination among Medicare enrollees is higher, Share Asian, not Hispanic tends to be lower: a weak link that holds when only places with similar density, income and education are compared. Share Asian, not Hispanic by US county | +0.26 | -0.18 |
| Flu vaccination among Medicare enrollees and Share American Indian or Alaska Native, not HispanicWhere Flu vaccination among Medicare enrollees is higher, Share American Indian or Alaska Native, not Hispanic tends to be lower: a weak link that holds when only places with similar density, income and education are compared, and inside states as well. Share American Indian or Alaska Native, not Hispanic by US county | -0.28 | -0.12 |
Highest and lowest
Of 3,117 counties reporting it. These are the two ends of a national ranking. For most measures, that ranking mostly sorts places by income and how urban they are. That is why the place pages compare each place with similar places instead.
