Like the birth rate, which of the following is expressed per 1000 pop…

The correct answer is Option (4) → Death rate

Option (1) Fertility rate — Incorrect. The fertility rate counts live births per 1000 women in the child-bearing age group, usually 15 to 49 years. Its base is only the women of that age group.

Option (2) Sex ratio — Incorrect. The sex ratio is the number of females per 1000 males. Its base is the male population, so it compares one part of the population with another.

Option (3) Infant mortality rate — Incorrect. The infant mortality rate is the number of deaths of babies before the age of one year per 1000 live births. Its base is the live births of that year.

Option (4) Death rate — Correct. The death rate is the number of deaths in a given area during a given time per 1000 population. It is built the same way as the birth rate, so both use the base of 1000 population.
