(a) NET MIGRATION-Net migration is the net total of migrants during the period, that is, the total number of immigrants less the annual number of emigrants, including both citizens and noncitizens.
NATURAL INCREASE - A natural increase is a population increase due to more births and less mortality.
ii. Identify at least 3 factors affecting Birth Rate, Death Rate, Migration.
1.Urbanization ; People living in urban areas:
(a) usually have better access to family planning services
(a)tend to have fewer children than those living in rural areas where children are needed to perform essential tasks.
2.Cost of raising and educating children.

The factors which affect death rate are;
1. Quality of living; such as, sanitation, dirty water, etc.
3. where you are born. e.g. if you were born in an LEDC you will have a lower life expectancy than those living in MEDC's due to their good resources, technology and facilities.
MEDC: Countries with more resources, salaries and housing accessibility's are MEDC’s (stage 3 or 4). A MEDC will have a lower birth rate and also a low death rate due to advanced Medical Technology. A country that is in stage 4, and has low baby population and high elderly population.
LEDC: A LEDC have a high birth rate and also a high death rate due to poor health care and a different type of diseases. Countries where life is hard (stage 1 or 2). The countries are also very poorly developed and the birth rate is high. Life is rather hard and people...
