Mapping the Census: A Dot for Every Person

Brandon Martin-Anderson, a graduate student at MIT’s Changing Places lab, was tired of seeing maps of U.S. population density cluttered by roads, bridges, county borders and other impediments.

Fortunately for us, he has the technological expertise to transform block data from the 2010 Census into points on a map. One point per person, and nothing else.

Ghost Counties (JanWillem Tulp, live version)

What you see here is housing data for all counties in the US, actually as a scatterplot. Here are some instructions and things to note:  

• the y-axis shows population. Note the logarithmic scale
• the x-axis for the bubbles shows the number of vacant homes per population
• the outer circle of the bubble shows the total number of homes
• the inner bubble shows the vacant number of homes
• each bubble has a line connects the bubble to yet another scale: the population / home ratio

These scans from the Ninth U.S. Census 1870 are truly fascinating. Check out the fiscal chart on page 35, the population pyramids on pages 40 and 41, the death charts on pages 45-46, and the disabilities on pages 49ff (including “insanity” and “idiocy”). There are also a few more treemap-like pages like the one above.

Incredible to think that all of these were done long before computers, by hand. The number crunching alone must have been a huge task, and then drawing these charts and transferring them onto plates for printing. Wow.
