176 school districts

There are still 176 U.S. school districts (of about 13,500 total) that are under federal oversight to ensure that they continue to uphold desegregation. One of them is in Jefferson County, Alabama, and, wouldn’t you know, it appears a bunch of white families are trying to break off from the Jefferson County district to form a new district.

144,352 tons of tomatoes per square mile

The Netherlands has been investing in new and improved ways to maximize the efficiency of humane farming. Acre for acre, the Dutch are the best on earth: using greenhouses they get 144,352 tons of tomatoes out of every square mile, with the closest runner up — Spain — getting a fraction of that. Essentially, the Dutch decided to be a food R&D lab for everyone else — the secret seems to be greenhouses — and the outcome is they export more food, judging by dollar value, than every country except the U.S. [National Geographic]

Square feet of office space managed by the startup WeWork, which offers co-working spaces and — increasingly — the service of running offices they themselves do not own.
