Explanation

A census is defined as the process of collecting data from every individual in a population, which directly matches the description in the question.
It provides a complete enumeration, not an estimate, of the population's characteristics.
The Census of India is a prime example of collecting primary data from the entire population for administrative and planning purposes.

Option A: An output report is the final product of data analysis, such as a published document or summary. It is not the method used to collect the initial data.
Option C: A market research survey is a tool to gather information from a sample of consumers to understand market dynamics. It does not involve collecting data from 100% of the population.
Option D: A community survey typically gathers data from a sample of residents within a specific geographic area. It is a form of sample survey, not a complete enumeration of the entire population.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Methods of Data Collection in Community Health and Research as background academic context rather than a clinical decision trigger.
Community health nurses rely on census data to understand the demographic profile of their service area, including age, sex, and socioeconomic status.
Census data provides the denominator for calculating vital health statistics like birth rates, death rates, and infant mortality rates, which are crucial for assessing community health status.
This information is essential for planning and allocating resources for public health programs, such as immunization drives, health camps, and maternal and child health services.

How to Approach the Question

First, identify the key phrase in the question: 'collected from 100% of the population'.
Understand that this phrase implies a complete and total count, not a partial one.
Evaluate the options based on this understanding. 'Census' is the specific term for a complete enumeration of a population.
Recognize that 'survey' (as in market research or community survey) usually implies studying a smaller 'sample' of the population.
Eliminate 'output report' as it is a result of data analysis, not a method of collection.
