If the replacement-level fertility rate of a population is higher than the total fertility rate,the population may have a negative growth rate.

If the replacement-level fertility rate (the rate at which births replace deaths, typically around 2.1 children per woman) is higher than the total fertility rate (the average number of children born to a woman in her reproductive years), it means that the population is having more children than is necessary to maintain the current population size. This can lead to overpopulation and strain on resources, but it does not necessarily mean that the population will have a negative growth rate. However, if the total fertility rate is lower than the replacement-level fertility rate, the population is likely to have a negative growth rate, as there are not enough births to replace deaths and maintain population size.
