Population Distribution Pattern of human settlement
Arithmetic density Total number of people divided by land area
Physiological density number of people per unit area
Carrying capacity population environment can support
Agricultural density ratio number of farmers to land
Ecumene Portion Earth's surface human can live
Population Pyramid bar graph representing distribution
Cohort Population various age in pop. pyramid
Sex ratio # of males per 100 females
Birth Deficit Bars of pop. pyramid rep. children
Dependency Ratio # of people under 15 & over 64
Crude Birth Rate (CBR) # of live births per 1,000 people
Crude Death Rate (CDR) # of deaths per 1,000 people
Total Fertility Rate (TFR) Average # of children a woman will have
Doubling Time # of years needed to double a pop.
Overpopulation # of people exceeds capacity

Child Mortality Rate) # of deaths in first 5 years of life
Demographic transition Process of change in society's from high birth rates to low birth/death rates
Rate of Natural Increase (NIR) Percentage of growth in a year (CBR)-(DBR)
J-Curve Population increase exponential growth
S-Curve Relates to growth and decline in rate of natural increase
Zero Population Growth (ZPG) Decline of total fertility rate to where (NIR) = 0
Expansive Population Pyramid High birth rate low life expectancy
Stationary Population Pyramid Not significantly growing or shrinking
Epidemiological transition model Distinctive cause of death in stage of Demographic transition model
Malthusian Theory British economist concluded rate of population growing faster than agriculture productivity
Pandemic Disease occurs over wide area affects high proportion
Boserup Theory: Theory stating agricultural methods depend on population size
