Final answer:
The TFR estimates the average number of children a woman will have during her childbearing years, while the CBR measures the number of live births per 1,000 people in the population over a year.
Step-by-step explanation:
The Total Fertility Rate (TFR) and Crude Birth Rate (CBR) are two different demographic metrics that measure birth statistics but in different ways. The TFR is an estimate of the average number of children a woman will have during her childbearing years, typically calculated for a specific population and period. In contrast, the CBR is a measure of the number of live births in a year per 1,000 people in the total population. While TFR focuses specifically on the fertility of women, the CBR provides a broader measure of birth rates across the entire population, regardless of the sex or age of individuals.
