Introduction to Global Population Distribution and Change
Population geography:
- Demography: the study of population
- Population geography: the study of the spatial expressions of population
o Where do they work, live?
▪ I.e. what is the spatial distribution of the population?
o How do they live?
▪ i.e. what is the density of human settlement?
▪ i.e. wat are the consequences of how we live?
o What resources do they use?
▪ i.e. are these resources equally accessible to all?
o What are their conditions of health and well-being?
Global Population Growth:
- What is the current (approx..) global population?
o 7.59 billion (Feb 2018)
- What was the global population (approx.) in 1999?
o 6.07 billion (July 1999)
o 1.5 billion people in this lifetime, 225,000 per day
- What is the orld’s largest y populatio outry?
o China= 1.41 billion
o India= 1.34 billion
o U.S. .32 billion
- Global population growth:
o Major thresholds and time periods
▪ Feb. 2018= 7.59 billion
▪ Took about 130 years to get to a population of 2 billion (1800-1930)
▪ Took 12 years to get an additional 1 billion (1999-2011) (population went
from 6 billion to 7 billion)
Nature and Consequences of Growth:
- Beyond simple growth, the key issues are:
o Where is occurs. There is a differential (unequal) population growth
▪ ~10% of births in more developed world
o Various consequences of this growth
▪ Consider:
• Provision of health care and social services
• Provision of food
• Resource scarcity (water, oil, etc.)
• Potential for conflict

Recall:
- Distribution: geographic phenomena can be explained with reference to the distance
between them and their spatial organization
o Density
o Dispersion
o Pattern
- Uneven distribution of people
o Clustered vs dispersed
o Factors: physical and human geographic
Concentrated populations:
- Europe
- Most of Asia
- Eastern North America
Dispersed Population:
- North Africa
- Northern North America
- Northern Eurasia
- Australia
Recall:
- The world is divided with respect to economic and social development
o This correlates with levels of population
o The ost populous outies ted ot to e part of the gloal ore
- What are consequences of this?
o A large number of people who live in poverty live with poor access to health-
care, education, etc.
Population Density:
Recall:
- Population density: the number of people occupying an area of land
Measures of Population Density:
- Arithmetic (crude): # of people per unit area of land
- Physiological: # of people per unit area of arable land
Limits?
- Are there limits to population growth, population density, and the capacity of the earth
to support our population?
- Overpopulation: when the number of people in an area exceeds the capacity of the
environment to support life at a decent standard of living
o A recognition that the environment can only sustain a certain population size
o What is a deet stadard of liig?
