What does "biggest city by area" mean?

The term "biggest city by area" refers to the total geographical expanse of a city, including its urban core, suburbs, and any surrounding land that falls under its jurisdiction. Unlike population size, which measures the number of residents, area size focuses on the physical boundaries of a city.

For example, a city like Mumbai may have a high population density due to its limited land area, whereas cities like Bengaluru or Hyderabad may cover a larger area with relatively lower population density. This distinction is important because a larger area often requires more extensive infrastructure, better connectivity, and efficient governance to ensure smooth functioning.

Urban expansion, driven by industrialisation, migration, and economic growth, has led to cities spreading outwards. This growth brings opportunities but also necessitates significant financial planning for infrastructure, property investments, and more.

 

Which is the largest city by population in India in 2025?

By 2025, Mumbai is expected to retain its position as the largest city in India by population. Known as the financial capital of the country, Mumbai is home to over 20 million people. Its thriving industries, job opportunities, and cultural significance continue to attract migrants from across India.

However, other cities like Delhi and Bengaluru are also witnessing rapid population growth. Delhi, with its rich history and status as the national capital, is a close contender, while Bengaluru, renowned as the IT hub of India, has seen a steady influx of professionals and entrepreneurs.

Managing such densely populated cities comes with unique challenges, including housing shortages, traffic congestion, and environmental concerns. If you are planning to relocate to or invest in these cities, financial stability is crucial. 

With Bajaj Finserv Loan Against Property, you can secure high-value funding to meet your relocation or investment needs without financial strain.

 

What is the difference between the biggest city by area and the biggest city by population?

Understanding the difference between the biggest city by area and the biggest city by population helps in recognising the varying challenges and opportunities each city presents:

  • Biggest city by area: Refers to the city with the largest geographical spread. For instance, cities like Hyderabad and Bengaluru are among the largest in terms of area, offering vast spaces for residential and commercial development.
  • Biggest city by population: Refers to the city with the highest number of residents, such as Mumbai or Delhi, where population density is a significant factor.

While large cities by area require robust infrastructure and connectivity to manage their expanse, cities with high populations need efficient housing, public transport, and waste management systems.

 

What are the challenges of managing such a large city?

Managing a large city, whether by area or population, comes with its own set of challenges. Here are some of the key issues faced by urban planners and administrators:

1. Infrastructure Development

Cities with vast areas require extensive infrastructure, including roads, public transport, and utilities like water and electricity. Ensuring connectivity between different parts of the city is a major challenge.

2. Population Density

Cities with high population density, like Mumbai, face issues such as overcrowding, housing shortages, and traffic congestion. Managing these requires innovative solutions and significant investments.

3. Environmental Concerns

Rapid urbanisation often leads to deforestation, pollution, and loss of biodiversity. Balancing development with environmental sustainability is a critical challenge.

4. Economic Disparities

Large cities often have stark contrasts between affluent areas and informal settlements. Bridging this gap requires inclusive policies and financial support for underprivileged communities.

5. Financial Preparedness

Urban expansion and relocation often involve significant costs, from property investments to infrastructure development. This is where financial solutions like
