Today's news that a measles-infected LinkedIn employee may have exposed hundreds of SF Transit riders to the disease is keeping the already hot vaccination debate burning.
For many people following the story, this serves as yet more evidence that the upper middle class and the rich are the most likely culprits for vaccine non-compliance.
It may sound counter-intuitive, but there's other evidence this may be true.
Recent vaccination data for kindergartners bolsters the theory: In 2013 the country's poorest state, Mississippi, had the highest rate of measles vaccine compliance at more than 99%. The worst state for measles vaccine compliance was the much wealthier Colorado, where the median household income is about 53% greater than Mississippi.

Why is this? Is it because wealthier and relatively better-educated people are more likely to be just entitled and confident enough in their own wisdom to flout 200+ years' worth of hard scientific evidence?
Whatever the reasons, there does seem to be some kind of economic correlation to vaccine compliance.
It's just not the correlation you'd might expect.
