text: average figure often conceals more than it reveals about the condition of the poor. Дй/ As noted above, in its place UNICEF has suggested using the indicator measuring GNP per capita of the poorest 40 per cent of a country's population. Other suggested alternatives include switching to a measurement of an Adjusted National Product (ADP), a Green National Product (GrNP) and a Physical Quality of Life Index (PQLI). 57/ It should also be kept in mind that a large proportion of the outcome of the production process expressed in GNP does not represent any benefit to the quality of life and of the environment. Thus, there are strong grounds for placing this indicator more on the periphery of concerns, rather than at the centre where it now still stands. 83. PQLI is probably the most frequently used alternative indicator to GNP. PQLI is a composite social indicator, combining a State's average life expectancy at age one and its infant mortality rate on a scale of 0 to 100 by setting zero as the worst level recorded by any country in the year 1950 and 100 as the best level expected to be achieved by any country by the year 2000. Adult literacy is the third indicator used in PQLI. These three indicators are then averaged to give PQLI on a scale of 0 to 100 for each State. UNICEF states that the PQLI is useful in that it "is relatively resistant to the inequality factor, reasonably free of ethnocentricity, reflective of many of the elements which are close proxies for the desired goal, reasonably easy to calculate and communicate, and lends itself readily to inter-country comparison and analysis". PQLI, of course, has weaknesses as well. The most notable is that there is no particular reason for giving equal 
analysis: The text discusses the limitations of using Gross National Product (GNP) as an indicator of a country's development and proposes alternative indicators such as the Physical Quality of Life Index (PQLI) that take into account social and environmental factors. This suggests that the category should be related to economic development, but with a focus on the social and environmental aspects rather than just economic growth.
