Census is taken once in every?

Appeared in: SCTIMST Staff Nurse - 2015 (Set-A)

Explanation

The census is the official process of counting a country's entire population and collecting demographic, economic, and social data.
In India, as in many other countries, the census is conducted decennially, which means once every 10 years.
This regular interval allows for tracking population trends, planning public services, and allocating resources effectively.
The last census in India was held in 2011. The first regular census was conducted in 1881.

Option A: A 5-year interval is too frequent for a massive and resource-intensive exercise like a full census.
Option C: A 15-year interval is not a standard frequency for census-taking in any country. The data would become too outdated for effective planning.
Option D: A 20-year interval is far too long. Population dynamics, including migration, birth rates, and death rates, change too rapidly, making data this old unreliable for policy and planning.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Frequency of Census as background academic context rather than a clinical decision trigger.
Census data is the backbone of community health nursing. It provides the denominator for calculating all major health indicators (e.g., IMR, MMR, birth/death rates), which are essential for assessing the health status of a community.
Nurses and health planners use census information to plan for resource allocation, including staffing, clinic locations, vaccine distribution, and targeted health campaigns for vulnerable populations (e.g., elderly, children).
What if? If a new industrial zone causes a rapid population boom in a rural area between censuses, community health nurses would use local surveys and health facility data to estimate the new population size to advocate for additional resources like a new sub-center or more ASHA workers.

How to Approach the Question

Identify the core concept of the question. The question asks for the time interval of the census.
Access your knowledge base regarding national statistics and public health administration.
Recall that the census is a major, large-scale national activity to count every person.
Remember the specific term 'decennial,' which means occurring every 10 years, is commonly associated with the census.
Compare this knowledge with the given options. The option '10 years' directly matches the standard frequency for the census in India.
Eliminate other options as they represent incorrect intervals for a complete census.
