The Dynamic Gravity dataset provides extensive country and country pair information for a total of 285 countries and territories, annually, between the years 1948 to 2016. This documentation extensively describes the methodology used for the creation of each variable and the information sources they are based on. Additionally, it provides a large collection of summary statistics to aid in the understanding of the resulting Dynamic Gravity dataset. This documentation is the result of ongoing professional research of USITC Staff and is solely meant to represent the opinions and professional research of individual authors. It is not meant to represent in any way the views of the U.S. International Trade Commission or any of its individual Commissioners. It is circulated to promote the active exchange of ideas between USITC Staff and recognized experts outside the USITC, professional devel- opment of Office Staff and increase data transparency by encouraging outside professional critique of staff research.
