Explanation

The dependency ratio is a key demographic indicator that measures the pressure on the productive population.
It is calculated by dividing the population of dependents (those under 15 and over 64) by the working-age population (ages 15-64).
This ratio is a derived statistic used extensively in economics, sociology, and public health to assess the socio-economic structure of a population.
A high dependency ratio suggests a greater financial and social burden on the workforce to support children and the elderly.

Option A: Life expectancy at birth is a statistical measure, but it's a projection of mortality trends, not a direct measure of population structure like the dependency ratio.
Option B: Sex ratio is a basic statistical comparison between the number of males and females. It doesn't provide the same level of socio-economic insight as the dependency ratio.
Option D: Population size is a fundamental statistic (a raw count), not a derived analytical indicator like the dependency ratio that shows a relationship between different population segments.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Demographic and statistical indicators in public health as background academic context rather than a clinical decision trigger.
Understanding the dependency ratio is crucial for public health planning. A high ratio signals a greater need for pediatric and geriatric healthcare services, which can strain healthcare systems.
Nurses in community health use this data to anticipate health needs, plan for resource allocation (e.g., more immunization clinics for children or chronic disease management programs for the elderly), and advocate for policies that support both dependents and caregivers.
What if? If a country experiences a 'demographic dividend' (a low dependency ratio due to a large working-age population), the focus of nursing might shift towards occupational health, wellness programs for the workforce, and family planning services to maintain a balanced population structure.

How to Approach the Question

First, analyze the question. It asks which indicator 'includes statistics'. Recognize that all options are demographic indicators and are inherently statistical.
This suggests the question is looking for the 'best' fit or a more complex, analytical statistic rather than a simple count or projection.
Evaluate each option: Population size is a raw count. Sex ratio is a simple ratio. Life expectancy is a projection. Dependency ratio is a calculated ratio that analyzes the structure of the population in terms of economic dependence.
Conclude that the dependency ratio is the most likely intended answer because it is a specific analytical tool derived from raw statistics to provide socio-economic insight.
