Indian Census: Mapping the Nation’s Pulse Through Data
Introduction
The Indian Census is one of the largest and most detailed administrative exercises in the world. Conducted every ten years by the Office of the Registrar General and Census Commissioner, India, under the Ministry of Home Affairs, it provides crucial data on the country’s demographic, social, and economic landscape. From policy-making to resource allocation, the census is the backbone of India’s developmental planning.
What is the Indian Census?
The Census of India is a decennial process that collects, compiles, analyzes, and disseminates information about the population of the country. It includes data on:
Population size and growth
Literacy rates
Gender composition
Employment status
Housing conditions
Migration patterns
Languages and religions
The first complete census in India was conducted in 1881, and it has been carried out every 10 years since then, with the last census conducted in 2011.
Objectives of the Indian Census
The primary aims of the Indian Census are:

How is the Census Conducted in India?
The Indian Census is carried out in two major phases:
1. House Listing and Housing Census

Records housing characteristics, amenities, and assets
2. Population Enumeration
