In 1960 the urban population meant 20.6% of the total population of Castile and León; in 1991 this percentage had risen to 42.3% and in 1998 it was approaching 43%, which indicates the progressive state of rural depopulation.
The phenomenon is also reflected in the number of municipalities with less than 100 inhabitants, which was multiplied by seven between 1960 and 1986. Outside the provincial capitals, cities such as Miranda de Ebro and Aranda de Duero in Province of Burgos, Ponferrada and San Andrés del Rabanedo in Province of León, Béjar in Province of Salamanca and Medina del Campo and Laguna de Duero in Province of Valladolid.
Of the 2248 municipalities of this community, the 2014 registry registered 1,986 with less than 1,000 inhabitants; 204 from 1,001 to 5,000; 35 from 5,001 to 10,000; 8 of 10,001 to 20,000; 6 of 20,001 to 50,000; 5 of 50,001 to 100,000 and 4 municipalities with more than 100,000 inhabitants.
