(i) Improvement in medical and health facilities:
Due to advanced medical and health facilities epidemics like the plague, cholera, malaria, smallpox, measles, TB, etc. have been controlled or eradicated.

This has reduced the death rate.

Due to an improvement in medical facilities and public health measures infant mortality has declined.
