Fecundity is said as the biological capacity of women to give birth to new one. The childbearing time of any women is known as fecundity. It continues from 15 to 49 year of age.

    Death is the natural factor of population change. Death always helps to decrease the population. Always the number of death should be higher than birth in order to decrease the population. But nowadays the death rate is becoming less due to health education, facilities of health services, maintenance of balance diet, proper care and daily exercise etc. If there will be less birth rate and more death rate then there will be less population.

    Internal migration is the migration which is done inside the boundary of a country. The movement of people from one place to another place inside the country is known as internal migration. It doesn't affect the country but it affects the place from where people has moved and the place in which they move in (i.e. both in place of origin and destination). The population of theplace of origin decreases whereas the population of the destination or the place where they have moved may increase. Nowadays we have seen people moving to the place where they can fulfill their all needs. For example: in our country, Nepal, people they migrate from Hill and Mountain to Terai Region as there are many facilities thanHilly Region and Mountain region. There are huge useof natural resources in the place where the flow of migration is high but in the place of origin all the services and facilities are not enough in the place from where they have moved due to the high density of population and people have to work hard for living their life.

    The movement of the people from one country to another country for the settlement is called international migration. People migrate from one country to another country because of good employment opportunities, education, health facility, and other good opportunities.
