Census

Step 1: Understand the administrative structure for census operations in India.
The Census of India is a massive decennial exercise.
The administrative machinery extends from the central government down to the local level.

Step 2: Identify the key census official at the district level.
At the district level, the District Magistrate/Collector is typically designated as the Principal Census Officer or the overall in-charge of census operations within their district.
They are responsible for the conduct and supervision of the census work in their jurisdiction, coordinating with various departments and enumeration staff.
While there might be specific "District Census Officers" appointed under them, the Collector holds the primary administrative responsibility.

Step 3: Evaluate the options.
Option (1) Joint Collector: An administrative officer who assists the Collector.
While involved, the Collector is the head.
Option (2) Collector (District Magistrate/DM): This is the chief administrative and revenue officer of a district and is typically vested with the overall responsibility for census operations in the district.
Option (3) Superintendent of Police (SP): The head of the police force in a district, responsible for law and order.
Not the chief census officer.
Option (4) Chief Executive Officer (CEO): This title is used in various contexts (e.
g.
, CEO of Zila Parishad, CEO of a company).
While a CEO of Zila Parishad is involved in rural local governance, the Collector/DM is the nodal officer for census.

Step 4: Confirm the responsible officer.
The District Collector/Magistrate is generally the principal authority for census operations at the district level.
This matches option (2).
