The crude death rate (CDR) is defined as the number of deaths occurring in a given year per 1,000 people in a population. This statistic provides a straightforward measure of mortality and is often used in demographic studies to assess the level of health and wellbeing in a given area.

When using the crude death rate, population size is taken into account, allowing for a standardized comparison across different regions and countries, regardless of their varying population sizes. This is crucial for understanding trends in mortality rates over time or in different geographic contexts.

The other options misinterpret the concept of CDR. For example, while some might think it reflects the percentage of deaths, that is a different metric that considers the total deaths relative to the total population but expressed in percentage terms rather than standardized per 1,000 individuals. Similarly, simply stating the total number of deaths without relating it to population size does not provide the standardized context that CDR offers. Lastly, the average lifespan relates to life expectancy and is not a direct measure of mortality within a specific year, which is what the CDR focuses on.
