India is the second-most populous country in the world with a population of over 1.3 billion. However, there are a few states in India that are sparsely populated. They are:

• Arunachal Pradesh: It is the least populated state in India with a population density of 17 people per square kilometer. The state covers an area of 83,743 square kilometers and has a population of just over 1.4 million.
  
  
• Mizoram: With a population density of 52 people per square kilometer, Mizoram is the second least populated state in India. The state covers an area of 21,081 square kilometers and has a population of just over 1 million.
  
  
• Manipur: Manipur is the third least populated state in India with a population density of 122 people per square kilometer. The state covers an area of 22,327 square kilometers and has a population of just over 3 million.
  
  
• Nagaland: With a population density of 119 people per square kilometer, Nagaland is the fourth least populated state in India. The state covers an area of 16,579 square kilometers and has a population of just over 2 million.
  
  
• Lakshadweep: It is the smallest union territory in India and has a population density of 2,013 people per square kilometer. The union territory covers an area of just 32 square kilometers and has a population of just over 65,000.
  
  

There are several reasons for low population density in these states:

• Geography: The hilly and mountainous terrain of these states makes it difficult for people to settle and cultivate crops.
  
  
• Climate: The extreme climate conditions in these states, such as heavy rainfall, snowfall, and cold temperatures, make it difficult for people to survive.
  
  
• Infrastructure: The lack of developed infrastructure, such as roads, electricity, and water supply, makes it difficult for people to live and work in these states.
  
  
• Migration: Many people from these states migrate to other parts of the country in search of better job opportunities and living conditions.
  
  

The low population density in these states has both positive and negative impacts:

• Positive impact: The low population density helps to preserve the natural beauty and biodiversity of these states. It also helps to maintain the unique cultural traditions and practices of the indigenous people.
  
  
• Negative impact: The low population density makes it difficult for these states to attract investment and development. It also makes it difficult for the government to provide basic services and amenities to the people living in these states.
  
  

The sparsely populated states of India face many challenges due to their low population density. However, they also offer unique opportunities for preserving the natural beauty and cultural traditions of India. As India continues to develop, it is important to ensure that these states are not left behind and are provided with the necessary infrastructure and services to support their growth
