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?
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???
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)
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
