This is the latest stage of research on the chronological series of capital stock in Spain and its autonomous regions, promoted by the BBV Foundation in collaboration with the Valencian Institute for Economic Research (IVIE). The incorporation of a new series of public investment and stock broken down by province, and of a national series broken down by sector and function, for the period 1964-1996, constitute the most important two new points of this edition. Coinciding with the publication of this new version, access to its statistical information is now available through Sophinet, the Regional Economic Database of the BBV Foundation.
