This paper analyses the period of economic development that Spain underwent between 1959 and 1975, focusing on small- and medium-sized firms across the whole range of industry. It is argued in this paper that small- and medium-sized firms played a crucial role in this process. The conclusion that may be drawn from the INE income data for small- and medium-sized enterprises is that these firms enjoyed the greatest growth over this period.
