The number of deaths over a given period divided by the person-years lived by the population over that period is expressed as the number of deaths per 1,000 population. This is called:

Explanation

The crude death rate (CDR) is the measure of mortality in a population.
It is calculated by taking the total number of deaths in a specific population over a given period (usually a year) and dividing it by the mid-year population.
This result is then multiplied by 1,000 to express the rate as the number of deaths per 1,000 individuals.
The term 'crude' signifies that the rate does not adjust for population characteristics like age or gender distribution.

Option A: The child mortality rate specifically measures deaths among children, typically under the age of five, not the entire population.
Option B: Life expectancy is an estimate of the average number of years a person is expected to live, not a rate of death within a specific period.
Option D: The morbidity rate measures the incidence or prevalence of disease and illness in a population, not death.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Definition of Crude Death Rate as background academic context rather than a clinical decision trigger.
Community health nurses use epidemiological data like the crude death rate to understand the overall health status of a community, identify health trends, and plan public health interventions.
High crude death rates in a specific area can signal underlying problems such as disease outbreaks, environmental hazards, or lack of access to healthcare, prompting further investigation and resource allocation.
What if? - If a community has a large elderly population, its crude death rate might be high even if the population is healthy. In this case, nurses would use age-adjusted death rates to get a more accurate picture of health and mortality risk, as it accounts for the population's age structure.

How to Approach the Question

First, carefully read the question to identify the key components of the definition provided: 'number of deaths', 'given period', 'population', and 'per 1,000 population'.
Analyze each option to see how it relates to the definition.
Eliminate 'morbidity rate' as it relates to illness, not death.
Eliminate 'child mortality rate' as it is specific to a particular age group (children), whereas the question refers to the general population.
Differentiate between 'life expectancy rate' (which is an average lifespan, not a rate of death) and 'crude death rate'.
Recognize that the definition provided exactly matches the formula and concept of the crude death rate.
