Q.Which one of the following states has the highest population growth rate during 2001 to 2011 decade ? (A) Manipur (B) Nagaland (C) Mizoram (D) Sikkim

The table gives us the percentage share of each country in the world population. For China, that figure is 17.2%, and for Brazil, it is 2.68%. To find the combined share of these two countries, we simply add their individual percentages.

17.2 + 2.68 = 19.88

Population growth refers to the change in the number of individuals in a population over a specific period. It is typically expressed as a percentage. When the number of deaths and emigration exceeds the number of births and immigration, a population experiences negative growth, meaning its total size decreases. Historically, major epidemics, famines, or wars have been the primary drivers of such declines.

1. Understanding Population Growth Trends in India:

   India's population has generally shown a continuous upward trend throughout its recorded history. However, there is one notable exception where the population actually declined. This period is often referred to as the "Great Divide" in India's demographic history.

2. Identifying the Decade of Negative Growth:

   Among the options provided, the decade from 1911 to 1921 stands out. During this ten-year period, India's population registered a decrease.

   Important

   The decade 1911-1921 is unique in India's demographic history for recording a negative population growth rate.

3. Reasons for Negative Growth (1911-1921): …

India's urbanisation story is deeply uneven. While some states have transformed into industrial and service hubs with sprawling cities, others remain anchored to agriculture and village life. Understanding which states fall at the lower end of the urbanisation spectrum tells us as much about economic structure as it does about geography and history.

Bihar stands out as one of India's least urbanised states. Despite being densely populated, the overwhelming majority of its people live in villages. The state's economy remains heavily agrarian, with limited industrial growth and few large urban centres beyond Patna. Historical underinvestment in infrastructure and industry has meant that rural-to-urban migration within the state has been modest; instead, many Biharis migrate out to cities in other states for work.

Himachal Pradesh presents a different picture but arrives at a similar outcome. This hill state's terrain makes large-scale urbanisation difficult. Settlements are scattered across valleys and slopes, and the economy leans on agriculture, horticulture, and tourism rather than manufacturing or services that typically concentrate populations in cities. Shimla and a few other towns exist, but they house only a small fraction of the state's people. …

Why urbanization projections matter

The movement of populations from rural to urban areas has been one of the defining demographic shifts of the past century. Understanding these trends helps governments plan infrastructure, housing, healthcare, and environmental policy. The United Nations tracks urbanization rates globally and produces long-term estimates based on current migration patterns, birth rates in urban versus rural areas, and economic development trajectories.

The urbanization trajectory

1. Historical baseline: In 1950, only about 30% of the world's population lived in urban areas. Cities were smaller, and most people worked in agriculture or rural industries.

2. Current state: As of the early 2020s, approximately 55–56% of the global population lives in urban areas. This represents a dramatic shift driven by industrialization, better urban employment opportunities, and rural-to-urban migration. …

Understanding population growth rates is crucial for comprehending demographic shifts and their implications for development planning. A population growth rate indicates how quickly the number of individuals in a population is increasing or decreasing over a specific period, usually a decade in the context of Indian censuses. This metric helps policymakers allocate resources, plan infrastructure, and address social needs effectively.

The decade from 2001 to 2011 saw varying population growth trends across India's states and union territories. While some states experienced significant increases, others showed more moderate growth, and a few even registered a decline in population. The states listed in the question—Manipur, Nagaland, Mizoram, and Sikkim—are all located in the northeastern part of India, a region known for its diverse demographic patterns.

Let us examine the population growth rates for each of these states during the 2001-2011 decade:

• Manipur: This state recorded a population growth rate of 24.50%. This indicates a substantial increase in its population over the ten-year period.
• Nagaland: Uniquely among Indian states, Nagaland registered a negative population growth rate of -0.58% during this decade. This means its population actually decreased slightly between 2001 and 2011, a rare demographic phenomenon in India.
  Note

  A negative growth rate signifies a decline in the total population, which can be influenced by factors such as out-migration, lower birth rates, or higher death rates.

• Mizoram: Mizoram experienced a robust growth rate of 23.48%, indicating a significant expansion of its population. …
