Arithmetic (Crude) Density Total number of people divided by total land area.
Physiological Population Density Number of people per unit of area sustainable for agriculture.
Arable Land Land suited for agriculture.

Overpopulation Circumstance for too many people for the land to support.

Population Explosion A sudden increase in the population
Zero Population Growth When crude birth rate equals crude death rate and natural increase rate approaches zero.
Demographic Momentum Tendency for growing population to continue growing after a fertility decline because of their young age distribution. This is important because once this happens a country moves to a different stage in the demographic transition model.
Natural Increase Population growth measured as the excess of live births over deaths; does not reflect either emigrant or immigrant movements.
Demographic Transition Model The steps through which a society progresses. 1- low growth. 2- high. 3- moderate. 4- low.
Demographic Equation NIR = CBR - CDR
