The term "Gross Reproduction Rate" refers to the number of daughters born to women of childbearing age in a given population. Some common synonyms for Gross Reproduction Rate include Net Reproduction Rate, Total Fertility Rate, and Birth Rate. Each of these terms refers to a different way of measuring fertility and population growth. Net Reproduction Rate, for example, takes into account the number of women who never have children, while Total Fertility Rate measures the average number of children a woman will have over her lifetime. Birth Rate, on the other hand, simply counts the number of births in a population over a given period of time.
