Transcript of Where Do People Live?

  • Where Do People Live?Chapter 3, Section 1

  • Reach Into Your BackgroundWould you like to live in a city or in the country?List some interesting things you could do if you lived far from a city.List the things you would enjoy most about a city.

  • What is Population Distribution?The worlds population (total number of people) is spread unevenly over the Earths surface.New York City vs. Sahara DesertPopulation distribution describes the way the population is spread out over the EarthThe reasons population is distributed as it is may seem unclear.Demographers study the populations of the worldExamine birth, marriage, deathWhy do people choose to live in a certain area?

  • Uneven Population DistributionLandforms affect where people liveFew people can live in mountainous or hot deserts with dry landMany factors make a location a good place for people to live.Bodies of water trade and travel; fresh water (drinking and farming)Flat coastal areasFlat, fertile soil grow food and build easilyPlains and valleys

  • Uneven Population DistributionOther factorsClimate temperate; adequate rainfallAbundant natural resources build houses and make productsMaps on Pgs. 56-57 in textbook

  • Populous ContinentsBecause of these factors, 81% of the Earths people (4.9 billion people) live in Asia, Europe, and North America.These 3 continents = 53% of worlds landFertile soil, plains, valleys, fresh water, rich in natural resources, good climates

  • Not Populous ContinentsOther continents have smaller populations partly because its hard to live there.Australia = 3 million square miles (size of the continental U.S.) but only 19 million people live thereAbout the same number of people live in the state of New YorkAustralias environment mostly desert/dry grassland; few rivers/little rainfallMost people live along the coasts.

  • Not Populous ContinentsAfrica landforms and climate limit population20% of the worlds land, but only 13% of worlds population.2 of the worlds largest deserts (north and south)Broad bands of land with little rainRainforest long the equatorMany people live along narrow coasts

  • Not Populous ContinentsSouth Africa population limited by landforms and climates340 million peopleLive along the Atlantic coastSoaring mountains, vast dry plains, thick rain forests

  • World Population Distribution

  • Population DensityPopulation Density the average number of people who live in a square mileHigh density country = people crowded togetherJapan has one of the highest population densities in the world.Almost all of its 126 million people live on only 16% of the land.Tokyo more than 25,000 people per square mile

  • Japans Population Density (2011)

  • Population DensityCanada = low population density9 people per square mileCanada is bigger than the United States, but only 31 million people live there.(Japan has 95 million more people.)Cool climate and short growing season affect population.

  • Canadas Population Density (2002)

  • Studying Population DensityDemographers divide the number of people living in a place by the number of square miles of that place.CaliforniaPopulation = 33,871,648 peopleLand Area = 155,973 square milesAverage Population Density = 217.2 people per square mile

  • Californias Population Density (2010)

  • Studying Population DensityOn a world population density map, different colors show areas with heavy population.Population Density Map vs. Physical Map worksheetCompare the landforms to the population density.Where do people tend to live?Some people do live in areas most of us would find uncomfortable frozen Arctic regions; herdersPeople have developed ways of life suited to their environment over many generations.
