Geography Write short note

2. From second stage to this stage, death rates are decreasing. Birth rates are also decreasing. Decrease in both birth rates and death rates, reduces the rate of growth of population. But actually, population is growing because the birth rates are higher than death rates.

3. In this stage, since the country is making progress, the income of the people is above the subsistence level and there is an improvement in the standard of living of the people. Poverty is also reducing.

4. There is development of technology as a result secondary and tertiary activities develop.

5. Due to increase in education level, people understand the importance of family planning so size of family reduces.

6. In short in stage 3 countries are moving from developing stage to developed stage.

• Birth rate and death rate are the important components of population change.
• Birth rate is the number of live births in a year per thousand population.
• Death rate is the number of deaths in a year per thousand population.
• Population growth depends upon birth rate and death rate in a year.
• Population growth occurs not only by increasing birth rate but also because of decreasing death rate.
• When birth rate is more than death rate, population increases.
• When birth rate is less than death rate, population decreases.
• If both, birth rate and death rate is same then population is said to remain stable. However, the birth rate and death rate being same is only a hypothetical situation.

2. Generally, mountains are thinly populated, plains are thickly populated and plateaus are moderately populated.

3. The mountains and hilly areas are less populated because of limited means of livelihood; agriculture is poorly developed and transportation facilities are limited. For example, north eastern states of India have less population due to hilly and mountainous relief.

4. On the other hand, plains are densely populated because of fertile soil and well-developed agriculture. Due to plain relief, it is easy to construct roads and develop industries. Better employment facilities attract people in these areas. For example, Ganga plains are thickly populated.

5. In short, we can say plains are densely populated and mountains and plateaus are sparsely populated.

• Stage 5 in Demographic Transition Theory is the last stage.
• In this stage the birth rate is very low and death rate is high. Therefore, the growth of population is slow or negative growth of population is seen.
• Due to large number of old people the death rate is high and due to a smaller number of young people birth rate is low.
• Tertiary activities are more developed and they contribute more to the economy.
• The standard of living of people is high, economic condition of the country is good.
• In this stage government provides high quality educational and medical facilities.
• Overall people are happy due to healthy environment and comfortable life.
• For example, Norway, Sweden, Finland are in this stage.

• Minerals are important raw materials in the development of industries.
• Therefore, industries develop where good quality minerals are available. Mining and industries generate employment for large number of people and hence skilled and semi¬skilled labourers attract to such regions and mining areas become densely populated.
• For example, Richest mineralised zone of India – Chota Nagpur region, Ruhr region of Germany (due to coal and iron mines) are densely populated.
• In some country’s valuable minerals like gold, silver, copper are mined. In such areas in spite of adverse climate and relief minerals are extracted. Also, the region around the mines are densely populated.
• For example, gold producing areas in Africa, mineral oil mines in the deserts of south-west Asia.

• Climate is the most important factor of all the factors influencing the distribution of population.
• Areas of extreme climate like too hot, too cold, too humid, too dry and region of very heavy rainfall are not comfortable for inhabitation of people. Such areas are sparsely populated.
• For example, polar regions where Eskimo and Lapps live are sparsely populated due to extreme cold climate. Sahara Desert is sparsely populated due to extreme hot climate.
• On the other hand, areas with equable climate, that is climate with not much seasonal variation attract people. People feel comfortable to stay in these areas.
• For example, coastal areas have dense population because of equable climate and wide scope for the development of agriculture, industries and trade.
