Población y tamaño municipal: reflexiones a partir del censo de 1991

This paper is an update on the grouping of the Spanish population by municipal demographic size. This intermediate scale analysis, although traditionally important, is not included in the publications of the results from de 1991 Population Census. These results go from the provincial to the municipal scales, skipping any intermediate states. Despite its limitations, this kind of classification has proved useful in the analysis of the behaviour of the municipalities. It has allowed to establish common paths in municipal demographic history (population growth, migration and their demographic structure)
