Question

Crude birth and death rates are not useful for comparisons because population characteristics may differ greatly, particularly with respect to age.​

Quizplus · Accepted Answer

Crude birth and death rates do not take into account differences in population age structures, which can greatly impact the rates. Therefore, they are not useful for comparisons between populations or over time. Age-standardized rates, which account for differences in age structures, are a more accurate measure for comparisons.
