|Term |Definition |
|Birth Rate |The number of people born each year per 1000 people. |
| |# of births / total population x 1000 = BR |
|Death Rate |The number of deaths per year per 1000 people. |
| |# of deaths / total population x 1000 = DR |
|Natural Increase Rate |The difference between the birth rate and the death rate of a country. |
| |Birth Rate- Death Rate= Natural Increase Rate |
|Immigration Rate |Refers to the number of people per 1000 population in one year who immigrate |
| |# Immigrants per year/ population x 1000= Immigration Rate |
|Emigration Rate |Refers to the number of people per 1000 population in one year who emigrate. |
| |# Emigrants per year/ population x 1000= Emigration Rate |
|Net Migration Rate |The difference between people immigrating to a country and people emigrating from the same country. |
| |Immigration Rate- Emigration Rate= Net Migration Rate |
