Population in Space and Time

Natural Change- Shows populations change for Japan between 1900 and 2000. Graphs total population, female, male, population change, and natural change.

Migration- A map of human migration throughout time. Starts from beginning of human history and shows how we have spread throughout the world. Started in Africa and migrated towards Asia.

Exponential Population Growth- Description of exponential growth. Also, click on run applet to view an animation of exponential growth. Exponential Growth shows how long it will take at a certain birth rate to reach maximum sub stainable population.         

Population Concentrations- Population distribution in the United States in 2000. Shows how the east coast is more heavily population. Highlights the main population concentrations in the United States.

Ten Largest Countries- Graph of the ten largest countries. Shows China’s and India’s populations are far larger than even the third largest countries population.

Population Growth

Survivorship- Table that shows the death probability at each age. Period life table for the United States in 2003. Solidifies that women have a higher life expectancy than men. As the table increases in age, men’s life expectancy decreases at a faster rate than women’s

Population Pyramid- Population pyramid for the United States from 1950 to 2050 by age and sex. Indicates that men and women are expected to live longer as time goes on. Pyramid increasingly gets wider as time goes on.

Demographic Transition- Explains the transformation from countries with high birth rate and high death rate, to countries with low death rate and low birth rate. Includes a model of the three stages of birth and death rates as a country develops.

Checks on Growth

Malthusian Theory – Describes the theory of Thomas Robert Malthusian. Also includes background history on Thomas Malthusian.

Logistic Population Curve- Explains the creator of the logistic curve, and how it can be read. Describes the three possible model outcomes.

Zero Population Growth- Has the four stages of demographic transition. In the fourth stage when the birth and death rates are equal is when zero population growth occurs.

Controlling the World’s Population- Describes the dangers of overpopulation the world. It also includes Malthusian theory to better explain the importance of population control.

Population Projections

Formula- Gives formulas for computing Geometric and Exponential Growth. Explains the meaning of each variable, and uses accurate data to compute future population projections.

Example- An example projection that explains the migration by race from 1990 to 2100 to the United States. Projects that by 2025 Whites will be migrating away from the United States.
