Learning Target #18 – Describe human population in terms of total population, distribution/density,

the demographic transition, and population pyramids.

King James 2000 BibleAnd you, be you fruitful, and multiply; bring forth abundantly in the earth, and multiply therein.

World Population Over Time

So what happened?

What factors caused population growth?

Key Terms

What about for a region…what else do we need to consider?

Examples: USA = 13.66 / 1000 USA = 2.06 children per

woman

USA = 8.39 /1000 USA = 78.62 years USA = 5.9 deaths / 1000

live births

USA = 5.27 /1000 USA = 0.9% (9/1000)

Immigration and Emigration!

across the

Earth?

More/better food and medicine

Moving into cities; $

Now it’s your turn…Pick a population topic and

geographize it!

Check for understanding…Based on what we have learned so far, what is wrong with this animated map of Earth’s population density over time?Learning Target #18 – Describe human population in terms of total population, distribution/density, the demographic transition, and population pyramids.
