What rate refers to the average number of children born to the women in a population during their reproductive years?

Question

To approach this question, I will evaluate what each term typically means in demography and which one matches the description given.
Option 1: total fertility rate. This is the average number of children that would be born to a woman over her lifetime if she experienced the current age-specific fertility rates throughout her reproductive years. This exactly aligns with the description of the question.
Option 2: population change. This phrase generally refers to the net difference between births, deaths, and migration affecting the size of a population, not the average number of children born per woman during reproductive years, so it does not fit the definition sought.
Option 3: future birth rate. This term is not a standard census or demographic rate; it sounds like a projection concept rather than a baseline average number of births per woman over time, making it an incorrect match for the description.
Option 4: crude birth rate. This is the number of live births per 1,000 people in a population per year, regardless of age or sex structure. It measures births relative to the total population, not the average births per woman over her reproductive years, so it’s not the right choice here.
Option 5: replacement-level fertility rate. This is the total fertility rate required to keep population size stable from one generation to the next (often about 2.1 births per woman in developed countries). Although related to fertility, it is a threshold level, not the average number of children a woman would have over her reproductive years, so it does not match the description.
