Fundamentals of Population: Fundamentals of Population: Location, Distribution, & DensityLocation, Distribution, & Density

Is it Crowded in here?

•Imagine that the number of students in our AP HuGe Class has doubled. List the effects of this, both positive and negative.

•Would you like to have more, fewer, or the same number of students in the class as now? WHY?

With a Partner…

• 1. What are the benefits / drawbacks of a society with a large / small population?

• 2. What effects does Geography have on the number of people in a place?

• 3. What services are easier to provide for an area of high population density?

What is Demography?• KEY THEMES…

• 1. DISTRIBUTION – total population # vs. where concentrated…

DENSITYWhy of Where

Themes Cont’d…

• 2. GROWTH – • Is this a problem???

THE TURNING POINT…

• THE Industrial Revolution

• Before / After Effects on Population?

Themes Cont’d…

• 3. MIGRATION

• Why do people move???

Themes Cont’d…• 4. POPULATION POLICIES –

• Why would a Gov’t want to control its population growth?

• How do they do this???

• Should they do this???

World Population Concentrations

Where do we go now?

• RUST BELT – • Decline

• SUN BELT – • Growth

Making the Count

• Census –

• Why does a country need to know where its population exactly is???

Population Density-

• Number of People per unit area (sq. mile)

• 2 types

World Population Density

1. Arithmetic Pop. Den.-

• Breaks down data evenly• Assumes pop. is spread out evenly across

space

• Misleading???• No country has an evenly distributed

population!!!

Arithmetic Pop. Den. Formula• Country Pop. / Total Land = People per unit

• Egypt Pop.= 69.8 million (69,800,000)• Egypt land Area = 384.3 thousand sq. mi• (384,300)• 69.8 / 384.3 = .1816 people per sq. mi. (182)• or (just stay consistent!!!)

• 69,800,000 / 384,300 = 181.6 (182)

People All Over Egypt?

2. Physiological Pop. Den.

• # of people per unit of ARABLE LAND-• Useable land (agriculturally reproductive)• NOT mountains, tundra, craters, canyons,

desert

• Accurate reading of where people are located• Shows population pressure• # ALWAYS Higher!!!

Physiological Pop. Den. FORMULA

• Country Pop. / Arable land = people per arable unit

• 1. Have to ask what % of this country’s land is arable

• To find Arable Land: • multiply total land by • arable land percentage (as a decimal)

EGYPT PHYSIO. Pop. Den.

• Egypt Pop.= 69.8 million (69,8000,000)• Egypt land Area = 384.3 th. sq. mi. (384,300)• Egypt % Arable Land = 2%

(Decimal Way) (Long Way)• Arable Land = 384.3 384300

* .02 = 7.686 * .02 =7686

• Total Pop / Arable land = People per Arable U.• 69.8 / 7.686 = 9.081 (9081)• 69800000 / 7686 = 9081
