Correct Answer: (d) 6
Note: Urbanization refers to a process that brings about dynamic changes in the domicile format. This change basically occurs in areas of population, size, structure and occupations. Occupationally, non-primary (agricultural) works take precedence in the urban inhabited areas. In developing countries like India, due to rural-urban relocation, the process of urbanization has gained more strength. Most of the cities in India were initially villages, which transformed into towns and then became cities due to the centralization of services. The Census Department of the Government of India has classified the urban centres into 6 tiers on the basis of population.
1. Tier-1 cities - 100,000 and above population
2. Tier-2 cities - 50,000 to 99,999 population
3. Tier-3 cities - 20,000 to 49,999 population
4. Tier-4 cities - 10,000 to 19,999 population
5. Tier-5 cities - 5000 to 9,999 population
6. Tier-6 cities - less than 5000 population
