Final answer:
The birth rate refers to the number of live births per 1,000 people in a year, while the total fertility rate refers to the average number of children a woman would have in her lifetime.
Step-by-step explanation:
The birth rate and the total fertility rate are both measurements used in population studies and demography but they measure different aspects of population growth.
The birth rate is a measure of the number of live births per 1,000 people in a population in a specific year. On the other hand, the total fertility rate measures the average number of children a woman would have in her lifetime (if she lived to the end of her childbearing years and bore children according to current age-specific fertility rates).
For example, if a country has a birth rate of 15 per 1,000 people, it means that in that year, for every 1,000 people, 15 babies were born. In contrast, if the total fertility rate is 2.1, it suggests that on average, a woman in that country would have 2.1 children in her lifetime.
