First, there are now seven distinct super-regions, defined by common economics and demographics, like the Pacific Coast and the Great Lakes. Within these, in addition to America’s main metro hubs, we find new urban archipelagos, including the Arizona Sun Corridor, from Phoenix to Tucson; the Front Range, from Salt Lake City to Denver to Albuquerque; the Cascadia belt, from Vancouver to Seattle; and the Piedmont Atlantic cluster, from Atlanta to Charlotte, N.C.
Federal policy should refocus on helping these nascent archipelagos prosper, and helping others emerge, in places like Minneapolis and Memphis, collectively forming a lattice of productive metro-regions efficiently connected through better highways, railways and fiber-optic cables: a United City-States of America.
Vox’s lead exposure risk map takes a nationwide look at a crisis some might have thought was limited to Flint, Michigan. “The areas where kids are at highest risk of lead exposure—an estimate calculated using government data about the surroundings—are scattered all across the country.” Lead exposure data is hard to come by, so exposure risk is calculated based on Washington State’s methodology, which uses age of housing and poverty as risk factors.

On Cartastrophe, Daniel Huffman points out the problems in Decision Desk HQ’s interactive cartograms for the U.S. presidential primaries, which maintain a state’s shape but resize the counties as the results come in. “Unfortunately, in so doing, they shuffle the counties around any old which way. The Lower Peninsula of Michigan has 68 counties in reality, the Upper Peninsula has 15. But Decision Desk HQ has shoved most of the counties into the Upper Peninsula, which now has 58, vs. 25 that remain in the Lower Peninsula,” Huffman writes. “This means that we can’t really see spatial patterns, which is sort of the point of having a map.” [via]
There was a time, not too long ago, when our Super Tuesday map would have been impossible to put together and display. Even earlier in the digital era, a complete vote-totals map wouldn’t have been available until every ballot was counted at the end of the night. (Not to mention that in the print-only era, no map would be available until two days after the vote, and then often only in black and white.)
FiveThirtyEight maps the Facebook likes of the U.S. presidential candidates: “If Facebook likes were votes, Bernie Sanders would be on pace to beat Hillary Clinton nationwide by a nearly 3-to-1 margin and Donald Trump to garner more support than Ted Cruz and Marco Rubio combined. Anything seems possible this year, but, still, be careful how you interpret these numbers: Facebook likes are not votes.” They ain’t kidding—Ben Carson?! [via]
Of the maps of the Democratic and Republican U.S. presidential primary and caucus results I’ve seen so far, I rather like the county-by-county maps done by Reddit user Mainstay17. Here’s one for the Democrats that includes the results from the Super Tuesday states:
For this exhibition, Scher has created a body of large-scale cartographic paintings focusing on the United States. Paintings as tall as seven feet depict the country swirling in torrents of information and undulating with colorful layers of hand-painted boundary lines, place names, and commentary. Different sets of data—population demographics, transportation flows, geography, and climate—are employed to make connections and establish patterns. While the information can in no way be interpreted as literal fact, the expression of it demonstrates a personalized understanding of the diversity of the United States.
Governing used interactive maps to measure the gentrification of the neighbourhoods of Boston (above) and 49 other cities as part of their report on gentrification in the United States last year. “While it has become much more prevalent, gentrification remains a phenomenon largely confined to select regions, not yet making its way into most urban areas. In the majority of cities reviewed, less than one-fifth of poorer, lower priced neighborhoods experienced gentrification. If all city neighborhoods are considered—including wealthier areas not eligible to gentrify—less than one of every ten tracts gentrified. Cities like Detroit, El Paso and Las Vegas experienced practically no gentrification at all.” [via]
