Question

Answer 1

Correct Answer: Health and family welfare

Rationale:

The National Family Health Survey (NFHS) is an extensive survey conducted in India to collect data on health and family welfare. It provides essential information on various health indicators, which helps in policy formulation and program implementation.
The primary focus of the NFHS is to gather data on reproductive health, child health, maternal health, nutrition, and family planning. This information is crucial for monitoring and improving public health programs.

Explanation of Other Options:

Economic development

Rationale: Economic development encompasses the processes by which a nation improves the economic, political, and social well-being of its people. It is not the primary focus of the NFHS, which is primarily concerned with health and family welfare indicators.

Housing and infrastructure

Rationale: Housing and infrastructure refer to the physical and organizational structures needed for the operation of a society, such as buildings, roads, and power supplies. While these factors can influence health, they are not the main subjects of the NFHS.

Agricultural production

Rationale: Agricultural production involves the processes and methods used to grow crops and raise livestock. This area is typically surveyed by agricultural departments or specialized surveys, not the NFHS, which is dedicated to health and family welfare.

Conclusion:

The National Family Health Survey (NFHS) primarily collects data on health and family welfare, focusing on areas such as reproductive health, child health, maternal health, nutrition, and family planning. This data is critical for the development and assessment of public health policies and programs in India.
