    Question

    Which of the following statement is

    false?
    A The crude birth and death rates are not relevant for comparison. Correct Answer Incorrect Answer
    B Gross reproduction rate takes into account the mortality factor. Correct Answer Incorrect Answer
    C Net reproduction rate cannot be greater than gross reproduction rate. Correct Answer Incorrect Answer
    D If net reproduction rate is > 1, then the population has a tendency to decrease. Correct Answer Incorrect Answer

    Solution

    In  population ecology  and  demography , the net reproduction rate, R0, is the average number of offspring (often specifically daughters) that would be born to a female if she passed through her lifetime conforming to the age-specific fertility and mortality rates of a given year. This rate is similar to the  gross reproduction rate  but takes into account that some females will die before completing their childbearing years. An R0 of one means that each generation of mothers is having exactly enough daughters to replace themselves in the population. If the R0 is less than one, the reproductive performance of the population is below replacement level.
