Explanation: Kolkata, the capital city of West Bengal, is a densely populated urban area with a population of around twelve million people. One of the significant challenges faced by the city is the high proportion of its population living in slums. Slums are areas characterized by substandard housing, inadequate living conditions, and a lack of basic amenities such as clean water, sanitation, and electricity. These areas often have high population densities and are home to a large number of urban poor.
The term "slum" is used to describe informal settlements where the housing and living conditions are below the minimum acceptable standards. In Kolkata, slums are a result of rapid urbanization, migration from rural areas, and the inability of the city to provide adequate housing for its growing population. The slums in Kolkata are often located on the outskirts of the city or in areas that are not suitable for formal housing, such as flood-prone areas or industrial zones.
According to various studies and reports, approximately one-third of Kolkata's population lives in slums. This means that around four million people are living in substandard conditions, which poses significant challenges for urban planning, public health, and socio-economic development. The high concentration of people in slums also leads to issues such as crime, pollution, and limited access to education and healthcare.
Understanding the distribution of the population in slums is crucial for addressing the socio-economic challenges faced by the city. Urban planners and policymakers need to focus on providing better living conditions, improving infrastructure, and creating opportunities for the urban poor. This includes initiatives such as slum upgrading, provision of basic amenities, and economic empowerment programs.
In conclusion, the correct answer to the question is that about one-third of Kolkata's twelve million people live in slums. This highlights the significant urbanization challenges and socio-economic issues faced by the city, which require comprehensive planning and intervention to improve the living conditions of its residents.
