Which of the following is the best to compare vital statistics of countries?

If we want to compare the death rates of two populations with different age-composition, the crude death rate is not the right yardstick This is because rates are only comparable if the populations upon which they are based ae comparable.It is cumbersome to use a series of age-specific death rates, hence &;age standardization&; is used to remove the confounding effect of different age groups.Park 23epg: 59
