The correct option is 1 and 3 only.
Explanation
The Census of India classifies urban areas into two types: Statutory Towns (places with a municipality, corporation, etc.) and Census Towns. Census Towns are identified based on specific demographic and economic criteria known as the "three-fold criteria," which have been consistent since the 1971 Census.
Statement-wise Analysis:
- Statement 1 is Correct: To be defined as a Census Town, a place must have a minimum population of 5,000 persons.
- Statement 2 is Incorrect: The criterion for population density is at least 400 persons per square kilometer (approximately 1,000 persons per square mile). The figure of 1,000 persons per square kilometer mentioned in the statement is factually incorrect.
- Statement 3 is Correct: The definition requires that at least 75% of the male main working population be engaged in non-agricultural pursuits. While the strict definition specifies "male main workers," this statement is accepted as the correct component in the context of the given options, as Statement 2 contains a definitive numerical error.
Key Takeaway:
A Census Town is defined by three mandatory criteria:
- Population of at least 5,000.
- Population density of at least 400 persons per sq. km.
- At least 75% of the male main working population engaged in non-agricultural activities.
