Open Datasets

As a market researcher, app producer and software entrepreneur, I use a lot of different data sets for either research or tell stories. Here are a few great repositories I use regularly:

Data sources for civic engagement

  1. City data has collected and analyzed data from numerous sources to create as complete and interesting profiles of all U.S. cities as we could.
  2. Envirofacts Envirofacts provides a single point of access to U.S. EPA environmental data contained in U.S. EPA databases. Interested parties from State and local governments, EPA or other Federal agencies, or individuals can search for information about environmental activities that may affect air, water, and land anywhere in the United States. Envirofacts makes it easy to find information using an address, ZIP Code, city, county, water body, or other geographic designation. Envirofacts make it easy to find information from all sources or within specific environmental subject areas, such as Waste, Water, Toxics, Air, Radiation, and Land. Experienced users can use more sophisticated capabilities such as maps or customized reporting.
  3. U.S. Census The American Community Survey 5 Year Data covers a broad range of topics about social, economic, demographic, and housing characteristics of the U.S. population.
