Smart Location Database - Download
US Environmental Protection Agency
The Smart Location Database (SLD) summarizes over 80 demographic, built environment, transit service, and destination accessibility attributes for every census block group in the United States. Future updates to the SLD will include additional attributes which summarize the relative location efficiency of a block group when compared to other block groups within the same metropolitan region. EPA also plans to periodically update attributes and add new attributes to reflect latest available data. A log of SLD updates is included in the SLD User Guide. See the user guide for a full description of data sources, data currency, and known limitations:
The Smart Location Database (SLD) enables the consistent comparison of different locations across the U.S. in terms of their land use characteristics, infrastructure, and accessibility to nearby destinations. SLD attributes were selected for their utility in travel demand modeling studies. However they may also be relevant to land use scenario planning, community development, and public health studies – particularly when obtaining local data is not possible or practical. Planned updates to the SLD will summarize these environment and accessibility characteristics in the form of a Smart Location Index that represents a block group’s relative location efficiency when compared to other block groups within the same metropolitan region.
