POPULATION PROCESS(FACTORS).

Common factors on which population of a country is dependent are-

1.Birth Rate.

Birth rate is the numbers of live birth per 1000 persons in a year.

2.Death Rate.

Death rate is the numbers of death per 1000 persons in a year.

3.Migration.

Migration is the major cause for population change.

Migration refers to the movement of peoples of a region to some other region .It may be external movement i.e,from one country to another or internal i.e,from one state/city of to another of a particular country.

In india 'push' and 'pull' factor are major cause of migration,from villages the people are 'pushed'to the cities for the job,education etc...and from cities peoples are 'pulled'to get the silence environment,and good living conditions.

Permanent migration refers to the migration of people for settling into another place permanently.while Temporary migration refers to the migration of people for some months and years due to occupation.

AGE COMPOSITION.

In india there are three types of Age composition.

They are-

1.Children.(upto18 yrs)

2.Adults.(18-65yrs)

3.Old Peoples.(above 65yrs)

Out of these Adult age is most productive and can help in the development of a country.

In india About 60%population is in adult age and 8%Old people and 32%Childrens.It is a good for our country future.

Sex ratio.It refers to the no. of females /1000 males.In india there are 944 females/every1000 males.

Hence, population is an important feature and we should do some efforts to make it an asset rather than a liability.Never forget that only people can make use of the resources.Poulation is itself a resource.
