Bot creates mesmerizing art out of satellite photos of U.S. census tracts

A Twitter bot created by New York–based artist and urban planner Neil Freeman is producing serial images of every census tract in the United States. Operating under the account @everytract, the project will eventually publish satellite photos of the entire country. The account's feed—a stream of landscape photos cut out along census tract boundaries placed against a white background—initially appears pretty monotonous. The bot posts every image with the census tract's government identification number and location, but includes no other information or commentary, and the satellite imagery is familiar to anyone who has ever used Google Maps. Image after image of Southern California suburbs seems to confirm the banality of American neighborhoods, but after scrolling through dozens of images, the photos get defamiliarized and nuanced differences start to become more apparent. Repetitive patterns emerge only to be broken by strange landscape anomalies—an open mine, perhaps, or an artificial oasis in the Mojave Desert. As the bot shifts from one state to another, the images shift from the green forests of the south to the tan deserts of the west to the white snowdrifts of the north. The posts become artifacts that testify to the incredible variety of American settlements. Because census tracts are designed to have comparable population sizes, the images vary wildly in scale, showing the range of densities across the country. "I was playing with the project of a book that included satellite images of every tract at the same scale," Freeman said, "but I abandoned it when I realized that for the smallest tracts to be visible, the largest ones, in rural Alaska, would have to be wall-sized." Freeman also said that the project highlights the geographic idiosyncrasies of every state: "Only about a hundred tracts in Arizona cover the vast majority of the state’s land, so if you blinked, you missed them. It’s really a very urban state. Arkansas, on the other hand, was small town after small town." Freeman, who has been creating similar work that combines data-sorting algorithms and urban planning for years, said that the root of the listing concept came from poet Allison Parrish’s 2007–2014 project , which posted every word in the English language. Freeman began the @everytract project this spring, and it will progress alphabetically through the states, posting every half hour and is scheduled to run for another three years and ten months. The account is currently making its way through Los Angeles, California.

Boomtown: Houston poised to overtake Chicago as country’s third-largest city by 2025

The Texas metropolis of Houston is famous (or perhaps infamous) for its sprawling footprint. But as recent census numbers affirm, that growth reflects more than just a lack of zoning—within 10 years, more people will live in Houston than Chicago, according to information from health departments in Illinois and Texas. (Read AN's feature examining Houston's first General Plan here.) Long the country's third-largest city, Chicago is projected to have just 2.5 million people by 2025. Houston is expected to surpass that number, possibly growing to 2.7 million residents. A June study by Houston's Rice University found “if both cities maintain their average growth rates of the last four years, Houston would surpass Chicago as the country's third most populous by 2030.” Previous data from the 2000 and 2010 censuses had forecast a similar changing of the guard, noting Chicago had lost 200,000 people in the millennium's first decade, while Houston gained nearly 119,000. But new data publicized by Business Insider suggests the Texas metropolis could overtake the Windy City sooner. Houston leads the nation in job growth, owing largely to its expanding population.

Pittsburgh, Washington, Buffalo lead nation in growth of bicycle commuters

Portland still dominates the American Community Survey ranking the 70 largest cities with the highest share of bike commuters, but the list shakes up some preconceptions when you count which cities had the largest growth in the share of bicycle commuters from 2000 to 2013. The League of American Bicyclists runs the numbers every year, pulling data from the U.S. Census Bureau's American Community Survey. This year's bike culture report card, as it were, has Portland, Washington, San Francisco, Minneapolis, and New Orleans topping its list of bicycle commuters as a percentage of total population. In total 13 cities report more than 2 percent of their population biking to and from work. Growth in that number is more startling. They're small overall numbers, perhaps inflating the percent change figure, but the growth since 1990 for eight cities is over 100 percent. The following cities had the largest growth in the share of bicycle commuters from 2000 to 2013:
