  • Demography: the study of populations (human, non-human lifeforms, and certain objects, like cars or light bulbs) 
  • Quantitative data: information that can be expressed numerically, often represented visually with graphs, tables, charts, and histograms 
  • Mathematical models: computational models based on various quantitative data inputs that generate predictions about future events
  • Exponential growth: development at an increasingly rapid rate in proportion to the growing total number or size
  • Columbian Exchange: the exchange of diseases, ideas, food crops, and populations between the New World and the Old World following the voyage to the Americas by Christopher Columbus in 1492
  • Replacement level fertility: when the population replaces itself 1:1 from one generation to the next (2.1 children per woman for humans)
  • Fertility rate: the average amount of children had by women in a given population
  • Population pyramid: a graphical illustration used by demographers to show the age distribution in a population  
  • Urbanization: the trend for human populations to increase disproportionately in cities 
  • Arable land: land suitable for the cultivation of crops
