In 1990, the Association changed its organizational structure to better reflect the growth and development of the field; the Regional Science Association International now serves as an umbrella organization overseeing three major superregional organizations in North America, Europe and the Pacific.

The main objectives of the Association are the fostering of exchange of ideas and the promotion of studies focusing on the region, including the utilization of tools, methods and theoretical frameworks, specifically designed for regional analysis as well as concept, procedures and analytical techniques of the various social and other sciences.

These objectives are supported through the acquaintance and discussion among its members and with scholars in related fields, by the encouragement of publication of scholarly studies and by performing services to aid the advancement of its members and the field of regional science.
