The United Watershed States of America

United Watershed States of America 2

In 1879, surveyor (and future USGS director) John Wesley Powell proposed that the boundaries of future western states be determined by watersheds, in order to avoid water use conflicts. John Lavey takes this proposal to its logical conclusion, imagining a U.S. in which all 50 states follow watershed boundaries. Via io9.

Fifty Equal States Redux

The United States Redrawn as Fifty States with Equal Population
In 2010 I blogged about Neil Freeman’s reimagined United States where the 50 states were redrawn so that each state had the same population. (That map had been circulating for a few years prior to that.) Neil has since produced a new version at the same address, with new boundaries and state names on a nicer map. Though it’s just as thought-provoking. Via Kottke.

Census Dotmap


Brandon Martin-Anderson’s Census Dotmap plots every person counted in the 2010 Census as a single dot on the map. Which is to say that there are 308,450,225 dots on the map. Zoom in and see (though it’s not labelled and can be confusing to navigate at higher zooms). I suppose this is the demographic equivalent of the 1:1 map of Borges’s “On Exactitude in Science.” Via Boing Boing.

Mapping the Nation

Book cover: Mapping the Nation Susan Schulten, a history professor at the University of Denver, writes to let me know about her new book, Mapping the Nation: History and Cartography in Nineteenth-Century America, out this month from University of Chicago Press.

From the publisher’s page: “Today, statistical and thematic maps are so ubiquitous that we take for granted that data will be arranged cartographically. Whether for urban planning, public health, marketing, or political strategy, maps have become everyday tools of social organization, governance, and economics. The world we inhabit—saturated with maps and graphic information—grew out of this sea change in spatial thought and representation in the nineteenth century, when Americans learned to see themselves and their nation in new dimensions.”

This sounds very interesting. Her previous book, The Geographical Imagination in America, 1880-1950, came out in 2001. I may have to pick up both: maps and the history of mentalities is too much to resist.

U.S. Life Expectancy by County

U.S. life expectancy by county, 2009

County-by-county life expectancy estimates released last month by the Institute for Health Metrics and Evaluation reveal a startling gap between the longest-lived and shortest-lived areas of the country: the difference can be as much as 15 years.

The range of life expectancies is so broad that in some counties, such as Stearns, Minnesota, lifespans rival some of the places where people live the longest—Japan, Hong Kong, and France—while in other counties, life expectancies are lower than places that spend far less on health care—Egypt, Indonesia, and Colombia. Even within states, there are large disparities. Women in Fairfax, Virginia, have among the best life expectancies in the world at 84.1 years, while in Sussex, Virginia, they have among the worst at 75.9 years.

And the situation isn’t improving either: “In 661 counties, life expectancy stopped dead or went backwards for women since 1999. By comparison, life expectancy for men stopped or reversed in 166 counties.” When people refer to the U.S. as a Third World country, this sort of thing—the disparity, the decline—is usually one of the reasons why.

A Fantasy Map of the U.S.

A map of the U.S. in the style of a fantasy map
Fantasy maps have a very specific style that is actually quite limiting. For an example of what would happen if all maps were subject to the same limitations as fantasy maps, have a look at what is described “a map of the United States à la Lord of the Rings”; it was posted to Reddit and edited there by divers hands. The version above had the gridlines removed and made more “antique.” It does look like the early Middle-earth maps done by Pauline Baynes and Christopher Tolkien. To match the movie maps, you’d have to replace all the text with overdone uncial calligraphy and Tengwar vowel marks, whereas maps in modern fantasy novels would lose the shading on the mountains and have all the text done in Lucida Calligraphy.
