What is the Difference Between Birth Rate and Fertility Rate?
🆚 Go to Comparative Table 🆚The difference between birth rate and fertility rate lies in the way they are calculated and the population groups they represent.
- Birth Rate: This is the number of live births per 1,000 population, calculated by dividing the number of live births in a population in a year by the midyear resident population. It looks at the entire population, including both males and females, and is not restricted to a specific age group.
- Fertility Rate: This is the total number of live births, regardless of the age of the mother, per 1,000 women of reproductive age (aged 15–44). It is a parameter of a specific group of individuals in the population, focusing on the childbearing years of women. There are different types of fertility rates, such as the general fertility rate and the total fertility rate.
In summary, birth rate is a parameter of the entire population, while fertility rate is a parameter of a specific group of individuals in the population, specifically women of reproductive age.
Comparative Table: Birth Rate vs Fertility Rate
The birth rate and fertility rate are both measures related to the number of births in a population, but they differ in their calculation and meaning. Here is a table highlighting the differences between the two:
| Birth Rate | Fertility Rate |
|---|---|
| Expressed as the annual number of births per 1,000 people in the population | Expressed as the total number of children that would be born to each woman in her lifetime, given the current age-specific fertility rates |
| Measures the number of live births per 1,000 people in a population in a year | Reveals the average number of births a hypothetical cohort of 1,000 women could have, if they experienced the same age-specific birth rates that were observed during a specific point in time |
| Does not take into account the age of the mother or the time period | Takes into account the age-specific birth rates of women between the ages of 10 and 49 using 5-year age groups (10-14, 15-19, 20-24, etc) |
| Useful for understanding the number of births in a population, but not for predicting population growth | Useful for understanding population growth when combined with mortality and migration rates |
In summary, the birth rate is a measure of the number of live births per 1,000 people in a population in a year, while the fertility rate is a measure of the average number of births a hypothetical cohort of 1,000 women could have, given the current age-specific fertility rates. The fertility rate is more useful for understanding population growth, as it takes into account the age of the mother and the time period, unlike the birth rate.
