| Term | Definition |
| Agricultural Density | Number of farmers per unit of arable land |
| Arithmetic Density | Average number of people per unit of land (usually square kilometer) |
| Population distribution | The pattern in which humans are spread out on Earth's surface |
| Ecumene | The portion of Earth's surface with permanent human settlement |
| Population Clusters | Heavily populated areas, esp: South Asia, East Asia, Southeast Asia, Europe |
| Metacity | City with more than 20 million residents (ex: Delhi, Karachi) |
| Megacity | City with more than 10 million residents (ex: Mumbai, Kolkata, Lahore) |
| mean center of population | the balancing point given the distribution of population (take a country, average out where the population is, the middle point!) |
| Population Density | Average number of people per unit of land (population density is not specific– agricultural, arithmetic, and physiological are all types of population densities) |
| arable land | land suitable for cultivation |
| Carrying capacity | The number of people a particular environment or place can support in a sustainable way. |
| Population Composition | Makeup of the population by age, sex, ethnic, racial, income, and educational background |
| age structure | breakdown of a population into different groups |
| Dependency ratio | "Number of dependents (under 15 & over 64) in a population that each 100 working–age people must support. (divide number of dependents by working age population)" |
| Youth dependency ratio | Number under 15 that every 100 working age person must support |
| Elderly dependency ratio | Number of elderly dependents in a population (older than 64) that every 100 working age person must support |
| High child dependency | "Youth dependency Higher than 45 percent, lower than 15 percent elderly dependency Pakistan is here!" |
| Moderate child dependency | "29–45 percent youth dependency, lower than 15% elderly dependency Brazil is here!" |
| Double Dependency | "Moderate youth dependency (29–45%); high elderly (15% or higher). USA is here!" |
| High elderly dependency | "Youth dependency under 29%, elderly is 15% or higher. Japan is here!" |
| Low overall dependency | "Youth: lower than 29%; Elderly: lower than 15% United Arab Emirates is here!" |
| GI | lived through WWII |
| Silent Generation | Born during the great depression/WWII |
| Baby Boomers | born after WWII |
| Gen X | born between 1965– 1980 |
| Gen Y | (Millennials): 1981–2000 (Pastel!) |
| Gen Z | (iGen? Centennials?): you!" |
| Sex ratio | Ratio of men to women |
| Androcentrism | culture has a preference for men |
| Demographic equation | Calculating total population of a place based on natural increase & migration over 1 year) |
| Crude Birth Rate (CBR) | average number of births per 1000 people |
| Low birth rate | CBR of 10–20 births per 1000 |
| Transitional birth rate | CBR of 20–30 births per 1000 |
| High birth rate | CBR of more than 30 births per 1000 |
| TFR (total fertility rate) | Average number of children born per woman during her reproductive lifetime |
| Replacement level fertility | TFR of 2.1 |
| Crude death rate (CDR) | number of deaths per year per 1000 |
| Infant mortality rate (IMR) | how many infants die within the first year of life per 1000 live births |
| Rate of natural increase (RNI) | difference between number of births and deaths in a given year, as percentage of total population (NOT 1000) |
| Child mortality | deaths of children under 5 |
| zero population growth | same number of births and deaths in a given year (RNI is 0) |
| Rule of 70 | calculates doubling time by dividing 70 by RNI |
| Doubling time | number of years it takes for a population to double in size |
| DTM (demographic transition model) | Crude birth rates & crude death rates, Rate of Natural increases, all presented as stages countries progress through due to industrialization & urbanization |
| Epidemiology | Branch of medicine that studies the diseases |
| DTM Stage 1: High stationary | High birth & death rates |
| DTM Stage 2: Early expanding | Death rates drop, birth rates remain high |
| DTM Stage 3: Late expanding | Birth rates decline, RNI declines |
| DTM stage 4: Low stationary | Birth rates & death rates are low |
| DTM stage 5: Natural decrease stage | Birth rates drop below replacement level |
| Malthusian theory | population will outgrow resources |
| cornucopians | population growth stimulates innovation, we will not hit a population breaking point |
| Boserup effect | increase in food production from better farming practices |
| Pronatalist policies | policies designed to increase population |
| antinatalist policies | Policies designed to decrease population |
| median age | the age that divides a population into two halves |
