Visualizing Geographic Data

October 5, 2013

A couple of months ago, on a whim, I crunched some numbers from the National Center for Education Statistics. I was curious how employment opportunities for academic librarians in the United States might have changed in recent years. I decided to look at the change that had occurred between 2000 and 2010. I ended up visualizing the results with a mapping tool from Many Eyes. I didn’t share the results anywhere. When I visited Many Eyes again today, I was surprised to find that my visualization had been featured on the site. Apparently someone liked it, so I thought it I would share it here.

As shown in the graphic, there were significant shifts in academic librarian positions in various states, ranging from a decline of 15% in Alaska to an increase of 22% in Minnesota. Clicking on the static image here will link you to a more interactive version on the Many Eyes site. I suspect that other factors are at work as well. For example, unlike its neighboring states in the South, Louisiana experienced a decline, a change that may be related to the economic impact of Hurricane Katrina.
