The Alliance for Biking and Walking has released its biannual that examines data on bicycling and walking in all 50 states, the 52 largest U.S. cities, and a select number of midsized cities. According to the Alliance, the report combines original research with over 20 government data sources to compile data on bicycling and walking levels and demographics, safety, funding, policies, infrastructure, education, public health indicators, and economic impacts.
