If you hadn't noticed, this is a presidential election year. I can recall many previous election years when I've groused over outrageous distortions of fact, but this year has been especially tough to suffer through.
The truth is that statistics collected by reliable, objective sources often put the lie to such distortions, and almost all of those sources and numbers can be found on the Internet. But guess what? That data isn't always as easy to discover as you might think. Much of it is buried in PDFs and comma-delimited files. Neither voters nor, sadly, many news organizations have the time or inclination to dig that stuff up.
For years I've seen various attempts to aggregate public data relevant to key issues of the day and make them available on the Internet in interactive graphical form. The latest effort, launching today, looks promising: Data USA is a free and open platform created collaboratively by Deloitte, MIT Media Lab, and Datawheel, a Media Lab spinoff.
Data USA is an impressive piece of work. Pick a U.S. location, industry, or occupation, and you get dozens of interactive charts that you can drill into for greater detail. Eight types of visualizations are offered, including clickable maps of the United States that serve up census data and treemaps that show relative proportions at a glance. For business analysts, policymakers, or students, this has obvious value, but the visualizations are so well executed anyone can have fun with it.
According to Matt Gentile, principal at Deloitte and federal government analytics lead, the intent of Data USA is to "tell a story" using multiple, related data sets. Much of the effort, he said, went into getting domain experts and data scientists to provide contextual frameworks for various subject areas. At launch, Data USA is focusing on jobs, skills, education, and health, with much of the underlying data gathered from the Census Bureau, the Department of Labor, the Department of Commerce, and the Department of Education.
All the data on Data USA is API-accessible and the code is open source. The idea is to launch a platform that will sustain itself over time, as developers build on it and integrate their own data sets.
Although Data USA excels at providing context, it's hardly the first platform for delivering visualization of open data to the general public. The World Bank, for example, offers a gargantuan quantity of free data on 213 countries, 20 topics each, updated on a continual basis. Although a commercial venture, Statista also serves up a ton of free visualizations; it has a particularly rich array of global business information. Google launched its Public Data Explorer in 2010 using technology it acquired from Hans Rosling's Gapminder Foundation, but as far as I can tell Google has lost interest in this project.
