Abstract:

The proposition that poor housing and congested living conditions have a detrimental impact on health has been promulgated for at least 150 years. At a minimum, two major causal mechanisms are thought to be involved in the relationship between crowding and physical health. First, high levels of household crowding can produce stress that leads to illness. Second, through shared physical proximity, household congestion contributes to the spread of communicable disease. The outcomes can be exacerbated by poor quality housing. A significant body of research, conducted primarily in affluent countries, has documented the detrimental effects of housing conditions on a variety of illnesses, including various contagious diseases. Poor housing has even been linked to high infant and adult mortality rates. The view that poor housing conditions and household crowding inevitably leads to poor health is challenged. however, by several observers, who question the role played by both crowding and housing quality. Most existing research has been conducted in affluent countries.
