I want to start this post off by saying income tax return data isn’t the best measure of income in a community, but outside of the census, there aren’t many sources that are a very good measure.
At the local level, data journalism isn’t exactly prevalent, especially in mid-size metros like Dayton. When I stumbled across sortable income tax data in 2013, it was one of the things that got me interested in writing a blog.
The reason I’m sharing these now is because last week the IRS released ZIP sortable data for 2014, and that is awesome not only because it gives a 5 year sample size, but also because I’d argue it wasn’t even until 2013 that a lot of #Dayton progress started.
Zip codes really don’t respect city lines, so I picked three east/central Dayton and three north/west Dayton zips to compare. Some of the results you might find interesting.
The first images are summaries of the three zips I analyzed. If you click through the slideshow, you'll see charts for each income level over the last 5 years, with a linear trendline. They're broken down by income levels of Up to $25k,$25k-50k, $50k-75k, and $100k+.
