| Demographic Transition Model | A four stage theory of population change that occurs over time in societies as these societies experience variations in levels of development, urbanization, industrialization, and other factors. |
| Demography | The study of the size, composition, and geographic distribution of human populations and how population changes due to fertility, mortality, and migration. |
| Dependency Ratio | The proportion of non-working aged individuals who draw upon social welfare and public services without contributions through income and other taxes. For example: the young will draw upon public funding for items like schools, while elderly will draw upon |
| Economics | A social science concerned with the study of human behavior related to material well being, wealth, and decision making related to scarcity of resources. |
| Epidemiological Transition Model | Theory that studies the complex changes in patterns of health and disease and the interaction of these patterns on demographic, economic, and sociologic determinants and consequences over time. |
| Erlich Theory | A Malthusian Theory presented in the 1960's that posits that a population bomb would cause utter destruction of human population; based upon developing countries entering stage two of the demographic transition model at that time; would be expanded to inc |

| Landforms | Four major site characteristics that exist in the natural landscape: plains, hills, plateaus, and mountains. |
| Life Expectancy | The average number of years a person would live if current mortality trends were to continue. |
| Malthusian Theory | The theory that agricultural production grows in a linear fashion, while population grows exponentially, leading to a crisis event where population would outstrip the earth's ability to feed the population of an area. |
| Medical Care (Health Care) | Spending and quality of health related care including preventative measures like exercise, screenings, etc. and treatment types like medications and therapy. |
| Migration | The expected permanent movement of a person or group of persons from one location to another. |
| Mortality | Concepts related to dying. (crude death rate, infant mortality rate). |
| Neo-Malthusian | The new Malthusians who believe that other natural resources will also be outstripped by human population growth and lead to crisis events. For example: oil, natural gas, fresh water. |
