Answers
Answer:
1.Rapid population growth in developing countries is because of several factors: limited access to family planning, religious beliefs, soperstitions, etc, but the main reason for the increase is lack of money by the population as a whole.
2.The rate of natural increase is the difference between birth and death rates. It measures the degree to which a population is growing. Since birth and death rates are measured as the number of births (or deaths) occurring per 1,000 population, the difference is divided by 10 to convert this rate into a percentage.
3.Social changes expected out of migration are the following:
(i) Economic Efficiency: People tend to work properly if they find a suitable environment.
(ii) Standard of Living: The standard of living of the immigrant improves as he/she moves to an area that is better than that where they already live.
(iii) Diversity: The immigrant belongs to a
different culture, and introduces that culture in the society he/she moves to hence diversity is introduced.
(iv) Conformity and Adaptability: The
immigrant has to adjust to the lifestyle if the region he/she moves to hence it makes him/ her more adaptable.
4.The loss of a person from rural areas, impact on the level of output and development of rural areas. The influx of workers in urban areas increases competition for the job, houses, school facilities etc. Having large population puts too much pressure on natural resources, amenities and services.
5.At the extreme, other countries are experiencing negative population growth. Again, this means more deaths and emigration, or the leaving of a country, than births and immigration, or entering of a country. ... When a population loses too many members, voids are created.
6.Rapid growth has led to uncontrolled urbanization, which has produced overcrowding, destitution, crime, pollution, and political turmoil. Rapid growth has outstripped increases in food production, and population pressure has led to the overuse of arable land and its destruction.
7.The two causes of urbanisation are natural population increase and rural to urban migration. Urbanisation affects all sizes of settlements from small villages to towns to cities, leading up to the growth of mega-cities which have more than ten million people.
