Morris included three indicators or say determinants for measuring the physical quality of life.

These three determinants are:

  1. Literacy,
  2. Life expectancy and
  3. Infant mortality rate.

Thus, PQLI = Literacy level + Life expectancy index + Infant mortality index.

After 2003, three more aspects were included in PQLI and the Quality of Life Index (QLI) was prepared in the world.
