Arizona: Saving Northerner's Lives Since 1912

New study results, via Tyler Cowen:

We estimate the effect of extreme weather on life expectancy in the US. ... However, the
increase in mortality following extreme heat appears entirely driven by
temporal displacement, while the increase in mortality following
extreme cold is long lasting. The aggregate effect of cold on mortality
is quantitatively large. We estimate that the number of annual deaths
attributable to cold temperature is 27,940 or 1.3% of total deaths in
the US. This effect is even larger in low income areas. Because the
U.S. population has been moving from cold Northeastern states to the
warmer Southwestern states, our findings have implications for
understanding the causes of long-term increases in life expectancy. We
calculate that every year, 5,400 deaths are delayed by changes in
exposure to cold temperature induced by mobility.
These longevity gains
associated with long term trends in geographical mobility account for
8%-15% of the total gains in life expectancy experienced by the US
population over the past 30 years
. Thus mobility is an important but
previously overlooked determinant of increased longevity in the United
States. We also find that the probability of moving to a state that has
fewer days of extreme cold is higher for the age groups that are
predicted to benefit more in terms of lower mortality compared to the
age groups that are predicted to benefit less.

Your welcome, America.
