In the course of writing last month’s post about U-haul’s no-nicotine policy, I created the following graph:
This visualization didn’t make the final cut, but it’s nonetheless cool. It demonstrates that smoking rates among Hispanics are far less responsive to income than those of other ethnic groups (though even for Hispanics, the relationship between income and smoking rates is statistically significant). I was surprised to find this relationship, but apparently it’s a known factor of the phenomenon called “the Hispanic Paradox” (alternatively known as the “Latino Paradox”).
The paradox is that, on average, American Hispanics live longer than their non-Hispanic white counterparts, even though the former tend to have lower incomes and less education. The causes aren’t entirely understood, but Hispanics’ low smoking rates are thought to be a major contributor.
Some of the difference in smoking rates can be explained by immigration. Latin American countries tend to have lower smoking rates than the United States. Among those born in the United States, only Mexican-Ameicans seem to retain lower smoking rates and the attendant mortality advantage over non-Hispanic whites. It will be interesting to see if the Paradox ebbs as native-born Hispanics begin to account for more of the Hispanic population.
The Hispanic Paradox illustrates the capricious power of cultural influence on real-world outcomes — and conversely forces us to confront our limited ability to re-engineer the world.
We tend to think of (the physical, policy, social, or economic) environment and choice as the chief determinants of human behavior and outcomes. But we are just as much a product of the commingling of genetics and culture. The paths before us are well-worn by our predecessors, and we would be arrogant to think we can wholly resist their inclinations.
