In the following decades, Santiago continued to grow unabated. In 1940, the city accumulated 952,075 inhabitants, in 1952 this figure rose to 1,350,409 residents and the census of 1960 totaled 1,907,378 santiaguinos. This growth was reflected in the urbanization of rural areas on the periphery, where families of middle and lower class with stable housing were established: in 1930 the urban area had an area of 6500 hectares, which in 1960 reached 20,900 and in 1980 to 38,296. Although most of the communities continued to grow, it is mainly concentrated in outlying communities such as Canyon to the west, Conchalí northern and La Cisterna and La Granja to the south. For the upper class, it began to approach the foothills of Las Condes and La Reina sector. The center, however, lost people leaving more space for the development of trade, banking and government.
