Four decades of the Spanish regional economy can now be analyzed thanks to this series of research projects, such as the one in this book, which corresponds to 1993, and which also incorporates provisional advance data for 1994 and 1995. Among the figures issued by this periodic research are those on population, employment, output and its breakdown by branches of economic activity, regional and provincial income, public and private consumption, gross capital formation, and the balance of goods and services. The series was started in 1957 by the Banco Bilbao Vizcaya’s Research Service, and is now continued by the BBV Foundation. It is now a classic in Spanish regional research.
