Concept: Different demographic indicators are used to measure population health and trends. One important indicator focuses specifically on deaths among infants.
Step 1: Understanding the definition.
The question refers to the number of deaths of children under one year of age per 1,000 live births.
Step 2: Identifying the correct term.
This definition exactly matches the Infant Mortality Rate (IMR), which is a key indicator of a country's healthcare system and overall development.
Step 3: Eliminating incorrect options.

• Birth Rate refers to number of births per 1,000 population.
• Mortality Rate is a general term for deaths in a population.
• Life Expectancy indicates average years a person is expected to live.

Conclusion:
Thus, the correct answer is Infant Mortality Rate.
