-Population & Demographic Tools-
How to examine the structure of a population: 1) Distribution
2) Density
3) Composition
1) -Spatial differentiation of population distribution patterns and processes
(variation).
-Where people live impacted by physical and social factors. Ie/ lay of land,
accessibility, natural resources, trade relations, and socioeconomic
prosperity)
-Population is very unevenly distributed on a global scale
-Asia so densely populated because it is arable land, good for cultivating
(farms).
-Main factor affecting global population distribution is CLIMATE.
-70% of Canadians are living along the USA/Canada border
Ecumene: Continuously inhabited area of a region (generally shaded pink on
a map)
-Distribution can also be about other characteristics such as age, race etc.
2) –Measure of how well a population is distributed.
-People per unit of space
-Crude density = total # people/ total land area
-‘Crude’ because it doesn’t speak to the variation in land, or the land
that may not be habitable
-Canada’s crude density= 4people/km2 (UN, 2015)
-When talking about density, distribution needs to be considered
-It is a scalar issue (relative to where you draw your boundaries)
3) –Internal characteristics of a population such as age and sex.
-What makes up or what is in a population
-Largely affected by social and economic factors
-Analyzed with population pyramids: Graphical representation of a
population based on its composition according to age and sex.
-They reveal trends and conditions of a country’s social, economic and
political situation.
Why use them?
-See how youthful or how old a population is
-How many are of working age
-Gender splits

Document Summary

How to examine the structure of a population: 1) distribution. 3) composition: -spatial differentiation of population distribution patterns and processes (variation). Where people live impacted by physical and social factors. Ie/ lay of land, accessibility, natural resources, trade relations, and socioeconomic prosperity) Population is very unevenly distributed on a global scale. Asia so densely populated because it is arable land, good for cultivating (farms). Main factor affecting global population distribution is climate. 70% of canadians are living along the usa/canada border. Ecumene: continuously inhabited area of a region (generally shaded pink on a map) Distribution can also be about other characteristics such as age, race etc: measure of how well a population is distributed. Crude density = total # people/ total land area. Crude" because it doesn"t speak to the variation in land, or the land that may not be habitable. When talking about density, distribution needs to be considered.
