Population is a dynamic phenomenon. The
numbers, distribution and composition of the
population are constantly changing. This is the
influence of the interaction of the three processes,
namely-births, deaths and migrations. Migration is the movement of
people across regions and territories. Migration
can be internal (within the country) or
international (between the countries).
Internal migration does not change the size
of the population, but influences the distribution
of population within the nation. Migration plays
a very significant role in changing the composition
and distribution of population.
