The replacement rate is typically considered to be 2.1, which means that each woman needs to have an average of 2.1 children in order to replace the population without relying on immigration. This is because some children will not survive to reproductive age and because not all individuals will have children. Therefore, a total fertility rate higher than 2.1 would lead to population growth over time, while a rate lower than 2.1 would lead to population decline. Choices A, C, and D are all too high to maintain a stable population without immigration.
