Population change means rise or fall in the population of a place. This change depends upon three factors i.e. deaths, births and migrations. Deaths more than births mean fall in the population growth and more births than deaths mean rise in the population growth. But there is another determinant to decide the population change i.e. migrations from one to place to another. Migration may be emigration or immigration. They together bring rise or fall in the population of different places. Thus population change depends upon three major factors i.e. Deaths, Birth and migrations (i.e. imigration and emigration).
