Question

For a region, the infant mortality rate is 28 per 1,000 live births, life expectancy at age one is 65 years, and the literacy rate is 74%. Using the standard PQLI scale (Infant Mortality Index: 229 = 0, 7 = 100; Life Expectancy at age 1 Index: 38 years = 0, 77 years = 100; Literacy Index = literacy rate itself), compute the PQLI for this region.

Accepted Answer

**Step 1: Infant Mortality Index (IMI)**
$$IMI = \dfrac{229 - 28}{229 - 7}	imes 100 = \dfrac{201}{222}	imes 100 = 90.54$$

**Step 2: Life Expectancy Index (LEI)**
$$LEI = \dfrac{65 - 38}{77 - 38}	imes 100 = \dfrac{27}{39}	imes 100 = 69.23$$

**Step 3: Literacy Index** = 74 (the literacy rate itself, already on a 0-100 scale).

**Step 4: PQLI**
$$PQLI = \dfrac{90.54 + 69.23 + 74}{3} = \dfrac{233.77}{3} = 77.92$$ …
