Unit 2 Flashcards
Demography
the study of numbers with births, deaths, income levels, gender, etc. that show the changing development of the human population
Density
the number of something in a specifically defined area
Concentration
how far apart an occurrence happens (the frequency)
Higher concentration
the events are closer together
lower concentration
the events are further apart form each other
Distrbution
where something is occurring
*two cities with the same density of people may have different distributions (evenly spread out vs. houses very close together
Spatial Association
matching patterns of distribution
-two or more phenomena may be related or associated with one another
Distribution patterns
shows how an event reoccurs predictably
3 kinds of distribution patterns
- Linear: an event occurs one after the other in a way that we are able to have an idea of when the next one will come
- Centralized point: occurs when an event clusters at a particular point
- Random point: there is no correlation between the events
*each event can happen unpredictably
Cartography
creating a map to show statistical data
Population concentration
How evenly or unevenly distributed the people are
people settle by water, fertile soil, and neutral climates
Carrying capacity
the amount of people that can be held in an area
Ecumene
places on earth’s surface where people live
- in other words, where on earth people live
Arithmetic Density
total number of people in an given area
- divide the pop. by the land area
Physiology Density
number of people supported by a unit area of arable land
- divide the pop. by the arable land area
Physiology Density
the number of people supported by a unit of arable land
shows how many people on one piece of land needs to get fed
- divide the pop. by the arable land area
Agricultural Density
the ration of the number of farmers to the amount to the amount of arable land.
- divide the pop. of farmers by the arable land area
