Performance of, components of PQLI is counted between –
**Core Concept**
The Physical Quality of Life Index (PQLI) is a composite indicator used to measure the quality of life in developing countries. It encompasses three essential components that contribute to the overall well-being of the population.
**Why the Correct Answer is Right**
The PQLI is composed of three primary components: literacy rate, infant mortality rate, and life expectancy at age one. These factors are chosen because they are critical determinants of human well-being and are easily measurable. Literacy rate reflects the level of education and cognitive ability, while infant mortality rate and life expectancy at age one are indicators of healthcare quality and access to essential services. These components are often used by policymakers and researchers to evaluate the effectiveness of development programs and track progress over time.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the PQLI is not solely focused on economic indicators, but rather on human development and well-being.
**Option B:** This option is incorrect because the Human Development Index (HDI) is a different composite indicator that includes life expectancy, education, and income, whereas the PQLI focuses on literacy rate, infant mortality rate, and life expectancy.
**Option C:** This option is incorrect because the Gross Domestic Product (GDP) is an economic indicator that does not directly reflect the quality of life or human well-being.
**Clinical Pearl / High-Yield Fact**
The PQLI is a useful tool for policymakers and researchers to evaluate the impact of development programs on human well-being, but it has limitations, such as not accounting for income inequality and other socioeconomic factors.
**Correct Answer: D. Literacy rate, infant mortality rate, and life expectancy at age one.**
