“Only 51% of adults today are married, according to census data. And 28% of all households now consist of just one person — the highest level in U.S. history. That second statistic may appear less dramatic than the first, but it’s actually changing much faster: The percentage of Americans living by themselves has doubled since 1960.”

If you’ve followed this blog for a while, you might recall the Social Regions of the United States according to our Facebook connections. The above map is a similar concept, showing what our state lines might look like if they were drawn based on who we communicate with most as determined by our cell phone calling data. The map based on SMS data is slightly different from the one based on actual phone calls, which I’d guess has to do with texting being a more strictly personal activity.

“After more than a decade of calculations and observations, a team of astronomers has revealed a monstrous 3D map of the stars. Covering a distance of 380 million light-years, it’s the most complete 3D atlas of the local universe ever made.”
ASTER visible-infrared image of a tornado’s path near Tuscaloosa, Alabama:
“In the picture, captured just days after the storm, pink represents vegetation and aqua is the absence of vegetation. The tornado ripped up everything in its path, scouring the Earth’s surface with its terrible force. The ‘tearing up’ of vegetation makes the tornado’s track stand out as a wide swath of aqua.”
Active Hate Groups Per One Million People By State
“the contiguous United States, color-coded by the change in population density from 2000 to 2010. In urban areas, deep blue indicates that the population doubled (or more), pure red means that everyone left, grey denotes no change, and the intermediate tones represent the spectrum of increases and decreases in-between. Below 5000 residents per square mile, these colors fade with the square root of density towards white, where no people lived in either year. We created these maps from the official U.S. Census 2000 and 2010 block-level population data and boundaries using custom-built cartographic software.”

A Facebook engineering intern creates a more official and worldwide version of The Social Regions of the United States:
“I was interested in seeing how geography and political borders affected where people lived relative to their friends. I wanted a visualization that would show which cities had a lot of friendships between them.
I began by taking a sample of about ten million pairs of friends from Apache Hive, our data warehouse. I combined that data with each user’s current city and summed the number of friends between each pair of cities. Then I merged the data with the longitude and latitude of each city… I defined weights for each pair of cities as a function of the Euclidean distance between them and the number of friends between them. Then I plotted lines between the pairs by weight, so that pairs of cities with the most friendships between them were drawn on top of the others. I used a color ramp from black to blue to white, with each line’s color depending on its weight. I also transformed some of the lines to wrap around the image, rather than spanning more than halfway around the world.
After a few minutes of rendering, the new plot appeared, and I was a bit taken aback by what I saw. The blob had turned into a surprisingly detailed map of the world. Not only were continents visible, certain international borders were apparent as well. “
