Question

Migrations change the number, distribution and composition of the population in _____________.
A.The area of departure
B.The area of arrival
C.Both the area of departure and arrival
D.The area of all cities

Answer 1

Hint: Population is the reference point at which is detected by all other elements and from which they draw value and meaning from that. Both 'Resources',' crises' and 'disasters' are relevant in comparison to human beings only. Their numbers, their distribution, their development and the essential characteristics or characteristics have the basic context for interpretation and understanding appreciating all facets of the environment.

Complete answer:
Population is a complex phenomena. The population's numbers, distribution and structure are continuously changing. This is the effect of the three cycles, including births, deaths and migrations.
Population increase refers to the change in the number of a country/inhabitants territories over a given period of time, such as over the last ten years. It is possible to express such a change in two ways: in terms of actual numbers and in terms of percentage change per year.
The movement of persons through regions and territories is migration. Internal migration (within the country) or foreign (between countries) could be possible. Internal migration does not alter the population size, but alters the population distribution within the country. In shifting the structure and distribution of the population, migration plays a very significant role.

In India owing to the "push" element in rural areas, most migration has been from rural to urban areas. There are the unfavourable circumstances of rural poverty and unemployment and the 'pull' of the city in terms of improved prospects for jobs and better living conditions. A major determinant of demographic transition is migration. In terms of age and sex ratio, it modifies not just the population scale, but also the population composition of urban and rural populations. Rural-urban migration in India has led to a gradual growth in the proportion of the population in cities and towns.

From these discussions we can conclude that “Both the area of departure and arrival” will change the Migrations number, distribution and composition of the population.

Hence, the correct answer is option (C).

Note: It is important to remember that there is a very big population in India. If a low annual rate is applied to a very large population, a large absolute increase is made. When more than a billion individuals are rising and at a lower rate, the overall amount added becomes very high.
