Physical quality of life index (PQLI) includes all, EXCEPT:
**Core Concept**
The Physical Quality of Life Index (PQLI) is a composite indicator that assesses the well-being of a country's population by combining three basic dimensions: literacy rate, infant mortality rate, and life expectancy at age one. This index aims to provide a comprehensive picture of a nation's quality of life, focusing on its physical aspects.
**Why the Correct Answer is Right**
The PQLI specifically includes three key components:
* Literacy rate, which measures the proportion of the population that can read and write.
* Infant mortality rate, which reflects the number of deaths per 1,000 live births within the first year of life.
* Life expectancy at age one, which estimates the average number of years a person is expected to live beyond the age of one.
**Why Each Wrong Option is Incorrect**
**Option A:**
* This option is not specified, so we cannot evaluate its correctness.
**Option B:**
* There is no widely recognized index that includes all the components mentioned in the question.
**Option C:**
* This option does not match any known quality of life index, and its components are not relevant to the PQLI.
**Clinical Pearl / High-Yield Fact**
The PQLI is a useful tool for comparing the physical well-being of different countries, but it has its limitations, as it does not account for other important aspects of quality of life, such as economic status, social indicators, and environmental factors.
**Correct Answer:** D.
