Comparing the 2018 Index and the 2013 Index

To track change over the last decade we evaluated the exact same variables from the 2013 5-year American Community Survey and compared to the most recent data. The 2013 ACS covers the period 2009-2013 and thus allows us to see the whole decade 2009-2018. We found that in 2018, there was a net change of three more tracts classified as vulnerable than in 2013.

Of the five vulnerability factors - high ratio of non-white persons, high ratio of renters, high ratio of persons lacking a college degree, high ratio of households below 80% of median income, and high ratio of children living in poverty - what changed between 2009 and 2018 to make more areas of Tucson and Pima County more vulnerable?

For those 16 census tracts that changed from Not Vulnerable to Vulnerable, most tracts became vulnerable due to change in just one factor. The most changed vulnerability factor was the share of children living in poverty, with 13 of the 16 newly vulnerable census tracts becoming vulnerable due to this factor; furthermore, three of those 13 tracts also had households move to under 80% of median income to increase the vulnerability of the tract.

For the 13 census tracts that changed from some level of vulnerability to Not Vulnerable, most tracts saw improvements in either household income or the share of children living in poverty, or both - basically a mirror image of those tracts that shifted into vulnerability. Neither ratio of renters nor the ratio of persons with a college degree in a given tract were instrumental in vulnerability changes in 2009-2018 decade.
