Ecumene | The portion of the Earth's surface that is covered by permanent human settlement. |
Arithmetic Density | The total number of people divided by the total land area. |
Physiological Density | the number of people per unit of area of arable land (land sutible for farming) |
Agricultural Density | The ratio of the number of farmers to the total amount of land suitable for agricultural. |
Crude Birth Rate (CBR) | The total number of live births in a year for every 1,000 people alive in the society |
Crude Death Rate (CDR) | The total number of deaths in a year for every 1,000 people alive in the society |
Natural Increase Rate (NIR) | The percentage growth of a population in a year, computed as the CBR minus the CDR |
Doubling Time | the number of years needed to double a population (assuming the NIR stays at a constant rate) |
Total Fertility Rate (TFR) | The average number of children a woman will have throughout her child-bearing years. |

Demographic Transition | The process of change in a society's population. |
Stage 1 | Low growth: CBR-high CDR-high NIR-stable |
Stage 2 | High growth: CBR-high CDR-drops NIR-increases |
Stage 3 | Moderate growth: CBR-drops CDR-low NIR-drops |
Stage 4 | Low growth: CBR-low CDR-low NIR-stable *zero population growth* |
Agricultural Revolution | The time when humans frist began to domesticate plants and animals. (stage 1) |
Industrial Revolution | A series of im provments in industrial technology that tranformed the process of manufacturing goods. (stage 2) |
