In 2005, the borough had a population of 404,458, 4.6% of the total population of the Federal District. The growth rate is 1.8% for the past decade, lower than the decade previous. However, a large percentage of the borough's population lives in poverty and many live illegally on ecological reserves, lacking basic services such as running water and drainage. In the past, houses in the area were constructed from adobe and wood from juniper trees, but today, most constructions are boxy cinderblock constructions, many of which are not painted. By the 2010 census its population had grown to 415,007 inhabitants, or 4.69% of Mexico City's total.
