Its use would be particularly interesting in a comparative sense, for instance in a comparison between other possible core indicators. Moreover, when the indicator for GNP per capita for the poorest 40 per cent of a State's population is unavailable, the PQLI can assist in supplementing its absence. 64/ Indicators relating to inadequate housing conditions still provoke controversy at the international level, with universal agreement about such indicators lacking at present. To a significant degree the utility of this indicator will be dependent on national or local circumstances and perspectives about housing adequacy. It is generally accepted that what is "adequate" in a rich State would constitute an unreasonably high demand on a poorer State. Likewise, a dwelling which could in many ways be adequate in a State of the South would often fall far short of standards of adequacy in a Northern State. The important point here is well stated by Louis Wirth: "Civilization can be judged, at least to some extent, by the minimum housing conditions which a society will tolerate for its members". See S. Leckie, "Housing as a human right". Environment and Urbanization. (London, October 1989), pp. 92-108. The importance of nationally defined indicators of "housing adequacy" is highlighted by the fact that many housing indicators used in industrialized States have until relatively recently been directly transferred to developing States. Whereas general principles relevant to adequate housing are transferable (protection against eviction, access to services, housing affordability and others), many are not.

**Analysis**
The text appears to be discussing various indicators and metrics related to human development, with a focus on basic needs, human rights, and development. It mentions specific indicators such as life expectancy, infant mortality, literacy rates, and housing conditions, which are often used to measure the well-being of populations.
