Powers of Ten: Census Edition is a data visualization project by Jia Zhang that allows viewers to explore U.S. Census data in a novel way. The project was inspired by the Ray and Charles Eames's two films Powers of Ten, which was released in 1968 (the "sketch" version) and 1977 (the "final" version). The Eames's film depicts a couple picnicking in Chicago. The camera then zooms out, depicting the couple from a distance ten times farther away every ten seconds, eventually revealing satellite images of Earth and, eventually, a diagram of space. Similarly, Zhang's visualization allows visitors to explore population statistics and demographic data of an increasingly larger portion of the United States. The map begins in a single neighborhood, or, census block group. From here, visitors view an entire census tract and, next, a census county. As visitors are presented with these larger geographical areas, the population figures on the screen are updated, and new demographic statistics are introduced. As visitors reload the homepage, different starting locations are presented. When visitors allow the site to access their location, they may see their own neighborhood.
