Correct Option
The correct option is
A-4, B-3, C-1, D-2
Explanation
Demographic indicators are statistical measures used to analyze population dynamics, health standards, and development levels. These metrics are fundamental to understanding the demographic transition and the quality of life within a country.
Detailed Matching
- A. Infant Mortality Rate (IMR): Matches with 4. Death of a child below one year of age. Specifically, IMR is defined as the number of deaths of children under one year of age per 1,000 live births in a given year. It is a sensitive indicator of a country's health infrastructure.
- B. Birth Rate: Matches with 3. Number of babies born for every 1,000 people. This refers to the Crude Birth Rate (CBR), which is the annual number of live births per 1,000 population.
- C. Death Rate: Matches with 1. Number of people per 1,000 who die during a period. This refers to the Crude Death Rate (CDR), which is the annual number of deaths per 1,000 population.
- D. Life Expectancy: Matches with 2. Average period that a person may expect to live. It represents the average number of years a newborn is expected to live if current mortality rates continue to apply.
Therefore, the correct sequence is A-4, B-3, C-1, D-2.
Key Takeaway
Infant Mortality Rate is calculated per 1,000 live births, whereas Birth Rate and Death Rate are calculated per 1,000 total population. Life Expectancy is a summary measure of overall mortality and health conditions.
