ABSTRACT
The technical and social requirements of housing can be defined by a number of parameters likely to be relatively consistent with basic healthy housing needs anywhere in the world. For example, as long ago as 1939, the American Public Health Association devised a set of housing principles that were widely adopted for housing hygiene policies in a number of countries and are still largely applicable today. [18] However, the detailed control measures, standards and policies have changed and will vary in accordance with national, political and economic considerations. Wide differences in technical and social requirements also exist between rural and urban areas.
