Household Income Inequality

The Washington Post published this dot plot graphic to explore inequality in household income across numerous American cities.

The chart, as most dot plots do, does a good job of showing where several distinct points within a set fall within the entire range of data. Or to put it into other words, where do the poorest, the richest, and the most middlest households in Philadelphia fall within all Philadelphia households? The data is interesting because you will begin to uncover some significant outliers. For example, by quick glance, the 50th percentile in both Detroit and Cleveland earn less than the 20th percentile in San Jose.

I am a graphic designer who focuses on information design. My day job? I am the data visualisation manager for the Federal Reserve Bank of Philadelphia. (This blog is my something I do on my own time and does not represent the views of the Fed, blah blah blah legal stuff.) And with my main interest in information design—be it in the shape of clear charts, maps, diagrams, or wayfinding systems—I am fortunate that my day job focuses on data visualisation. Outside of work, I try to stay busy with personal design work. Away from the world of design, I enjoy cooking and reading and am interested in various subjects from history and geography to politics to science to the arts. And I allow all of them to influence my work.
