Core-Periphery Model
A model that describes that economic, political, and cultural power is distributed between dominant core regions and dependent peripheral regions (the area around the core, or the periphery, is dependent on the core in the middle).
Peters Projection (Gall-Peters)
A map that maintains area but distorts shape.
Mercator Projection
A map in which meridians are mapped to equally spaced vertical lines and circles of latitudes are horizontal lines.
Goodes-Homosline Projection
A map that maintains area but divides oceans, distorting distance.
Robinson Projection
A map that equally distorts shape, area, distance, and direction.
Scale
A direct connection between a unit of measurement on a map and actual distance on Earth. Small scales show large areas whereas large scales show small areas (1:1).
Isoline Map
A map that includes lines that connect points of equal value (looks like map of jet streams).
Cartogram
A map in which size on the map equals value (such as the map where countries are redrawn based on population).
Dot Density Map
A map that uses dots which communicate the frequency of data or population.
Proportional Symbol Map
A map in which symbol sizes are proportional to data values.
Chloropleth Map
A map in which colors and shading represent information within boundaries (think of maps showing democratic/republican party in US).
Malthus Population Catastrophe
Belief that the population is growing much too fast for the agricultural land/food supply we have to sustain/feed the population. Eventually, theoretically, all will starve.
Neo-Malthusians
Accepted the basic tenants of Mathus’ theories but focused more on regional growth rather than international.
Boserup’s Hypothesis of Population (anti-Malthusian)
Anti-Malthusian belief that population growth pushes farmers to discover more effective and productive farming techniques to cater to more customers and produce more profit, thereby producing enough food to take care of the growing population.
Population Pyramid Components
A bar graph used to display the age and gender distributions in a population that is broken into percentages of each gender and age group of five years.

Demographic Transition Model (DTM)
A model used to explain and predict population. Based on the assumption that all countries pass through four stages, Stage 1 countries have a high death rate, a high birth rate, and a low total population; Stage 2 countries have a high birth rate, a declining death rate, and an increasing population; Stage 3 countries have a quickly declining birth rate, a declining death rate, and an increasing population; Stage 4 countries have a low birth rate, low death rate, and high/increasing total population; and the hypothetical Stage 5 includes a stabilizing population with a low death rate and an even lower birth rate.

Epidemiologic Transition Model
A DTM for death at each stage (Stage 1, famine and infectious disease; Stage 2, epidemic diseases and overcrowding; Stage 3 and 4, human created diseases and diseases of the elderly).

Gravity Model of Spatial Interaction
The model that states that most migrants go short distances unless a large city or population center is the ultimate destination (they are more willing to travel longer distances). The model compares the population of two cities and their distance to figure out the “pull”. Population 1 * Population 2 (in millions) /Distance.
Ravenstein’s Laws of Migration
Laws that state that migration patterns are still based on basic principles: migrants go short distances (distance decay); long distance migration usually involves a large city (gravity model); rural populations are likely to move to urban areas; individuals are more likely to migrate than families; and every migration causes a counterstream. This applies to reasons, distance, and characteristics of migrants.
Zelinsky Model of Migration Transition
Migration patterns based on the DTM (Stage 1, season or cyclic movement and no migration; Stage 2, most migration, from farms to cities and internationally to higher stage nations; Stage 3 and 4, internal migration or within nation migration from cities to suburbs).

Indo-European Language
A family that includes the Germanic, Romance, Baltic-Slavic, and Indo-Iranian branches.
I-E Language Diffusion Theories (Agriculture, Conquest)
Agriculture language diffusion theory dictates that the first euro speakers lived in present day Turkey and through the trading of food and agricultural technology, they spread their language over many other areas. Conquest language diffusion theory claims that the reason language diffused over other areas was because many groups conquested each other, and the conquested groups were forced to learn the new language of the invader (Romans, Greeks, etc.).
Domino Theory
A foreign policy theory that speculated that if one land in a region came under an influence, then the surrounding countries would follow in a domino effect, suggesting that a small change in one place will cause another one nearby. This was used mainly with communism.
