The next wave of new residents was a result of the 1985 Mexico City earthquake. While the structures of the colonia were not heavily affected, the area received a large influx of others from more affected areas. This increased the population, but it also increased pressure to build more affordable housing. Since that time a number of groups representing the poor have pushed for more affordable housing in the area. This has created conflict with older residents who wish to retain the older mansions and other constructions as well as the more traditional feel of the colonia. The Instituto de Vivienda de Distrito Federal has built low income housing in the colonia, both to increase the number of area residents as to provide housing to those with scarce resources. Thirty seven of these new constructions were built in the early 2000s and have led to complaints that they do not fit in with many of the traditional structures.
