Mumbai-Delhi-Kolkata-Chennai

Understanding Urban Agglomerations and Population Ranking

This question asks us to rank four major urban agglomerations in India based on their population size according to the Census of India, 2011. An urban agglomeration (UA) is a continuous urban spread constituting a town and its adjoining outgrowths (OGs), or two or more physically contiguous towns together with or without their outgrowths.

To correctly answer this, we need the population data for each specific urban agglomeration as recorded in the 2011 Census. Let's look at the approximate population figures for the urban agglomerations mentioned:

Urban Agglomeration Approximate Population (Census 2011)
Mumbai UA 18.4 million
Delhi UA 16.3 million
Kolkata UA 14.1 million
Chennai UA 8.7 million

Ranking Urban Agglomerations by Population (Descending Order)

We need to arrange these urban agglomerations from the largest population to the smallest population (descending order). Comparing the approximate population figures from the 2011 Census:

  • Mumbai UA has the highest population at approximately 18.4 million.
  • Delhi UA is second with approximately 16.3 million.
  • Kolkata UA is third with approximately 14.1 million.
  • Chennai UA is fourth with approximately 8.7 million.

Therefore, the correct descending order of these urban agglomerations by population size according to Census 2011 is:

Mumbai > Delhi > Kolkata > Chennai

Evaluating the Options

Let's compare this order with the given options:

  • Option 1: Delhi-Mumbai-Kolkata-Chennai (Incorrect, Delhi is smaller than Mumbai)
  • Option 2: Mumbai-Delhi-Kolkata-Chennai (Matches our derived order)
  • Option 3: Mumbai-Kolkata-Delhi-Chennai (Incorrect, Delhi is larger than Kolkata)
  • Option 4: Kolkata-Chennai-Mumbai-Delhi (Incorrect, this order is much different)

Based on the Census 2011 population data for these urban agglomerations, the correct arrangement in descending order is Mumbai, followed by Delhi, then Kolkata, and finally Chennai.

2 Delhi UA 16.3 million
3 Kolkata UA 14.1 million
4 Chennai UA 8.7 million

Additional Information: Understanding Census Data and Urban Agglomerations

The Census of India provides crucial demographic data, including population counts for cities and urban agglomerations. Understanding the definition of an urban agglomeration is important:

  • It includes a core town or city and its surrounding urban outgrowths.
  • It can also include two or more contiguous towns forming a single urban area.
  • The concept helps in analyzing urban spread and the overall population size of large metropolitan regions beyond just the administrative city limits.
  • Population figures for UAs are typically higher than for the core municipal corporation areas.

Population data from the Census helps in urban planning, resource allocation, and understanding demographic trends.
