Welcome to the U.S. City Open Data Census! This site provides an overview of the degree of openness of certain key datasets in cities across the country. The table below reflects the most recent submission as of 2018 or 2019. See submissions from 2017 and earlier here. Read more about what has changed from the old version. At the moment, cities are ordered alphabetically; you can order by rank by double-clicking the "Rank" header.
