Population Geography Where do people live …and why??

Population Concerns: 3/4 of the worlds population live on approximately 5% of the earths surface!! WG6A, 6B, 8C Ask students why they think this is so (answers on next slide) Why are there are more people living in certain area? Fewer people in other areas? Most live between 20 and 60 degrees N latitude..why do you think this is so? This is a Goodes Interrupted/Equal Area map projection Five most populous countries (in order) China, India, US, Indonesia, Brazil Ask students why this is so…India will pass China in the students lifetime (China one child policy, India is experiencing a populaion growth)

People Tend to Live Where There is/Are: Seaports Good water sources Nice climate Fertile soil Urban areas (jobs etc) Transportation Resources Technology (would you live somewhere w/o electricity, cable or internet & phone service??)

World Population Growth: Let’s look at how population has grown over time… WG7C Dot video embedded on lower left hand corner! 7 Billion and Counting Video

Population Pyramids Inverted bar graphs that show: Age Distributions in a particular area (city, state country etc) Sex Ratio: Male vs. Female WG7A What does a population Pyramid show us? (more on these in a separate lesson!) What is happening in Italy? Russia? Nigeria?

Total # of live births for every 1000 people. Birth Rate: Total # of live births for every 1000 people. Why is the BR so low in some areas? Basically, why are infants dying at a more rapid rate in some areas?

Total number of deaths for every 1000 people. Death Rate: Total number of deaths for every 1000 people. DR high in developing countries = lack of medical care, nutrition Why is the death rate high in some areas & low in others? Look at Africa & eastern Europe, Afghanistan & Pakistan. What do these countries have in common? WAR!!!

Migration: Why do people move? Push Factors Pull Factors WG7B, 7C Have students come up with these as a class… Some examples: PUSH: plagues, wars, famine, PULL: jobs/industrial revolution, better education opportunities

Rate of Natural Increase: The % growth of population in a year (BR-DR = RONI) WG8C What do you think is happening where the population is exploding/growing? What do you think the US & Europe might have looked like during the Industrial Revolution (better technology = able to grow more crops = able to feed more people = people having more children. Similar with the Green Revolution in India (push to grow more crops, feed more people – thus populaiton explosion)

Infant Mortality: Number of deaths of children under the age 1 per 1000 people in the population. WG7C High infant mortality tends to result in higher fertility rates as families seek “insurance” for the loss of children. In many countries children are the primary caretakers for their parents. Infant mortality is very high in developing countries. For instance, some African countries have an infant mortality rate that is over 10%.

Life Expectancy = How long a person will live. People live LONGER in developed/industrialized countries - better medical care. WG 7A Q: Statistically, women live longer than men. Why? A: Less stressful jobs (1950’s more men worked manual labor & stressful jobs. Women worked more in the home)

Let’s Recap… LOW Birth Rates HIGH Death Rates HIGH Infant Mortality Developing Countries Industrialized Nation LOW Birth Rates HIGH Death Rates HIGH Infant Mortality Life Expectancy = LOW (dying young) Nat Geo Are You Typical? Video HIGH /EVEN Birth Rates LOW Death Rates LOW Infant Mortality Life Expectancy = High (live to be old) We will talk more about Demographic Transition Stages in the next units…
