This article provides an analysis of job supply by Spanish firms and the demand for work, and the mismatch that occurs between these two variables. Data are taken for the year 2006, with particular attention to jobs offered by firms that require people with university degrees or other higher education qualifications. Demand and supply are broken down into several characteristics for the purposes of analysis: the level of studies; the professional category; the type of job contract; and the working day and salary. (Contains 5 tables, 5 figures, 2 online resources, and 6 endnotes.)
