Overcrowding

Actions That Make a Difference

  • To improve housing conditions and strengthen communities:

  • Build housing that meets appropriate standards for ventilation, density, and habitable space per person. The American Society of Heating, Refrigeration and Air-Conditioning Engineers and the International Society of Indoor Air Quality are among those recommending and evaluating healthy standards.

Actions That Make a Difference

  • Provide resources that allow the urban poor to own land and build or improve their own housing. Efforts to organize and strengthen communities should emphasize local assets and resiliency.

  • Promote community input and collective efforts to improve living conditions. Non-governmental organizations with proven track records in engaging affected populations need resources, technical assistance, and other support to manage these efforts.

Actions That Make a Difference

  • Develop creative planning, land-use, and transportation policies that accommodate sustainable growth. Effective leadership, broad-based participation, and partnerships are essential tools for success.
