Which of the following is not the Cause of Population?
Climate Change
Understanding Factors Affecting Population
The question asks us to identify which option is NOT a cause of population. This likely refers to factors that cause population growth or significant changes in population distribution and density, often leading to a "population explosion" or increased "urbanisation". Let's examine each option provided.
Analyzing the Options Related to Population Change
We need to consider how each factor influences the number of people or where they live.
- Population explosion: This term itself describes a rapid increase in the size of the population. While often used as a description or a phenomenon, it is usually a result of factors like high birth rates and low death rates, not a cause of population growth itself in the sense of being an underlying driving force like socio-economic factors or technological advancements. However, within the context of potential options, it represents the phenomenon of rapid population increase.
- Heavy Urbanisation: Urbanisation is the increase in the proportion of people living in urban areas. Heavy urbanisation implies a large movement of people from rural to urban areas or high growth within cities. While it doesn't directly cause global population increase (it's about redistribution), growth rates can sometimes be higher in urban areas due to migration and birth rates. More importantly, factors *driving* urbanisation (like industrialization and job opportunities) are linked to economic development, which also affects population trends. So, urbanisation is closely associated with population dynamics, particularly density and distribution.
- Climate Change: Climate change refers to long-term shifts in temperatures and weather patterns. It is primarily caused by human activities, particularly the emission of greenhouse gases, which are linked to industrialization, energy consumption, and land use changes that are driven by factors like population growth and economic development. Climate change itself is generally considered an *effect* of these human activities and population-related pressures, not a primary *cause* of population increase. While climate change can indirectly affect population (e.g., through migration due to environmental disasters, impacting mortality or birth rates in specific regions), it is not a fundamental cause driving the overall global population size change in the same way that birth rates, death rates, or socio-economic factors are.
- Industrialization: Industrialization is a period of social and economic change that transforms a human group from an agrarian society into an industrial one. Historically, industrialization has been associated with significant population growth. Advances in agriculture, medicine, and technology during industrialization led to increased food production, improved sanitation, and better healthcare, resulting in lower death rates and higher life expectancy. Industrial opportunities also encouraged migration and urban growth. Therefore, industrialization is considered a significant historical cause of population growth and urbanisation.
Comparing Potential Causes of Population Change
Let's summarize the typical relationship of each option with population change:
| Factor | Typical Relationship with Population Change |
|---|---|
| Population explosion | A term describing rapid population increase (the phenomenon itself). |
| Heavy Urbanisation | Redistribution of population, often linked to underlying causes of population growth (e.g., industrialization). |
| Climate Change | Generally considered an effect of human activities, including population growth and industrialization, rather than a cause of population increase. |
| Industrialization | Historically a major driver (cause) of population growth and urbanisation due to improved living conditions and economic opportunities. |
Conclusion on the Cause of Population
Based on common understanding, Industrialization and processes leading to Urbanisation are considered factors that have caused population growth and redistribution. "Population explosion" describes the outcome of such causes. Climate Change, however, is primarily seen as a consequence of human activities associated with population growth and industrialization, not a cause that drives the increase in population numbers itself.
Therefore, Climate Change is the factor that is NOT typically considered a direct cause of population growth or the existence of population itself.
Revision Table: Population and Related Factors
| Term | Definition/Relationship to Population |
|---|---|
| Population | The total number of inhabitants of a particular town, area, or country. |
| Population Growth | Increase in the number of individuals in a population. Caused by factors like birth rates, death rates, and migration. |
| Population Explosion | A sudden, large increase in the size of a population. An outcome of rapid growth. |
| Urbanisation | The process by which towns and cities grow and a higher percentage of the population comes to live in urban areas. Influenced by population growth and migration. |
| Industrialization | Societal shift to manufacturing-based economy. Historically a major cause of population growth. |
| Climate Change | Long-term changes in weather patterns. Primarily an effect of human activities, including those driven by population and industrialization. |
Additional Information: Drivers of Population Growth
Historical and ongoing population growth is primarily driven by changes in birth rates, death rates, and migration. Key factors influencing these rates include:
- Improvements in Healthcare and Sanitation: Leads to lower death rates and increased life expectancy.
- Agricultural Advancements: Increase food production, supporting larger populations.
- Economic Development: Can influence both birth rates (initially higher, then lower as societies develop) and migration patterns.
- Education: Particularly education for women, which is often linked to lower birth rates.
- Cultural and Social Factors: Norms around family size, marriage age, etc.
- Migration: Movement of people between regions or countries affects local/regional population size, though not global population directly.
Understanding these drivers helps distinguish between causes and effects when studying population dynamics.

Wheat is primarily a crop of which of the following zone?
Direction (Q46. to Q50.) Read the given passage carefully and answer following five questions:
India has 640,867 villages according to the Census 2011 out of which 597,608 (93.2 per cent) are inhabited villages. However, the distribution of rural population is not uniform throughout the country. You might have noted that the states, like Bihar and Sikkim have very high percentage of rural population. The states of Goa and Maharashtra have only little over half of their total population residing in villages. The Union Territories, on the other hand, have smaller proportion of rural population, except Dadra and Nagar Haveli (53.38 per cent).
The size of villages also varies considerably. It is less than 200 persons in the hill states of north-eastern India, Western Rajasthan and Rann of Kachchh and as high as 17 thousand persons in the states of Kerala and in parts of Maharashtra. A thorough examination of the pattern of distribution of rural population of India reveals that both at intra-State and inter-State levels, the relative degree of urbanization and extent of rural-urban migration regulate the concentration of rural population.
You have noted that contrary to rural population, the proportion of urban population (31.16 per cent) in India is quite low but it is showing a much faster rate of growth over the decades. The growth rate of urban population has accelerated due to enhanced economic development and improvement in health and hygienic conditions. The distribution of urban population too, as in the case of total population, has a wide variation throughout the country.
Which one of the following is not a reason to accelerate the urbanization?
