Regional science is a field of the social sciences concerned with analytical approaches to problems that are specifically urban, rural, or regional. Topics in regional science include, but are not limited to location theory or spatial economics, location modeling, transportation, migration analysis, land use and urban development, interindustry analysis, environmental and ecological analysis, resource management, urban and regional policy analysis, geographical information systems, and spatial data analysis. In the broadest sense, any social science analysis that has a spatial dimension is embraced by regional scientists.
Regional science was founded in the late 1940s when some economists began to become dissatisfied with the low level of regional economic analysis and felt an urge to upgrade it. But even in this early era, the founders of regional science expected to catch the interest of people from a wide variety of disciplines. Regional science's formal roots date to the aggressive campaigns by Walter Isard and his supporters to promote the "objective" and "scientific" analysis of settlement, industrial location, and urban development. Isard targeted key universities and campaigned tirelessly. Accordingly, the Regional Science Association was founded in 1954, when the core group of scholars and practitioners held its first meetings independent from those initially held as sessions of the annual meetings of the American Economics Association. A reason for meeting independently undoubtedly was the group's desire to extend the new science beyond the rather restrictive world of economists and have natural scientists, psychologists, anthropologists, lawyers, sociologists, political scientists, planners, and geographers join the club. Now called the Regional Science Association International, it maintains subnational and international associations, journals, and a conference circuit (notably in North America, continental Europe, Japan, and South Korea). Membership in the RSAI continues to grow.
