For each geography included, the significant basemap layers are boundaries, cities, rivers, and roads. This basemap information is available for Canada, Europe, Mexico, the United States and the World. In addition, where possible, demographic data is provided for subnational boundaries such as states, counties, or their equivalents. The ArcGIS StreetMap USA disks contain the ArcGIS StreetMap USA data sets and the U.S. data sets needed to support the ArcGIS StreetMap USA extension. ESRI Data is available for 2016, 2012, 2010, 2008, 2006 and 2004.
