Cities and the fixed-gear bike index

The Priceonomics blog has an excellent post on US cities and their fixie index. They started with the notion that fixed-gear bikes are a strong indicator of "hipsterness", but found that Portland and Brooklyn may not be the fixie/hipster agglomerations that they are made out to be. It is the American cities that are growing and highly educated that tend to have thriving bicycle communities. It is highly recommended reading.
