The US Census recently released demographic information for census tracts for 2015. Here are some quick maps for Franklin County for median household income.

First, median household income for both 2010 and 2015.

And the % change between 2010-2015.

As can be seen, a lot of the greatest improvements over the 5-year period were around Downtown, the Near East Side, North High, South High and around some of the higher-income suburbs like Upper Arlington and the New Albany area.
