Agricultural Density - Ratio of the number of farmers to the amount of arable
land.
Low- MDC
High- LDC
Physiological Density - Ratio of the number of people to arable land.
High- LDC
Low- MDC
Arithmetic Density - Ratio of the number of population by the land area.
Ecumene - Places of permanent human settlement are formed.
Example: New York
London
Nonecumene - Places where there is not permanent human settlement.
Example: Antarctica

Epidemiological Transition - How people die in each stage of demographic
transitions.
Stage 1-2: Die by epidemics and pandemics
Example: Black plague
Stage 3-3: Die by man- made diseases
Example: Cancer
Pronatalist - Expansive- promotes childbirth
example: Italy
Antinatalist - Restrictive- restricting childbirth
Examples: China
India
Stage 5 DTM - Negative NIR- declining population
Very low CBR
Increasing CDR
Examples: Russia
Italy

Stage 4 DTM - Low growth- marked by very low birth and death rates
No long term natural increase and possibly a decrease
ZPG
Examples: Sweden
Japan
Stage 3 DTM - Moderate growth- marked by rapid decline in birth rates and steady
decline in death rates
NIR is moderate
Gap between CBR and CDR is narrower in stage 3 than 2
Examples: America
China
Stage 2 DTM - High growth- marked by declining death rates and very high birth
rates
High NIR
Europe and North American in industrial revolution
Africa, Asia, and Latin America in 1950
