The death rate of 2 countries can be best demonstrated by:

Standardized death rates are hypothetical rates used for the comparison of moality experience of one country with that of another or of the same country at two different times. There are two methods of standardization: direct and indirect. If the age specific death rates of the places under comparison are available, the direct method is used; otherwise the indirect method. Following data are required for calculating the standardized death rates: The standard population and its age-wise breakdown. Usually, the population at the last census is taken as the standard population. The age-wise breakdown of the population of the two countries (or of the country at two different times) being compared. The crude death rate of the standard population. For the direct method of standardization, the age specific death rates of the countries under comparison. Ref: Principles of community Medicine by B. Sridhar Rao; 5th edition; Page-95
