Learning Objectives Today we will be able to identify the main aspects of population studies in order to develop and understanding of the wide variety of issues in human geography. Today we will be able to identify the main aspects of population studies in order to develop and understanding of the wide variety of issues in human geography. Four Key Issues of Demography in Human Geography More people are alive today than at any other time in human history More people are alive today than at any other time in human history The worlds population increased at a faster rate during the second half of the twentieth century than ever before. The worlds population increased at a faster rate during the second half of the twentieth century than ever before. Virtually all population growth today occurs in less developed countries (LDCs) Virtually all population growth today occurs in less developed countries (LDCs) What PUSHES people away?

Population concentrations Population concentrations Two-thirds of the worlds population are in four regions:Two-thirds of the worlds population are in four regions: East Asia East Asia South Asia South Asia Europe Europe Southeast Asia Southeast Asia Population Cartograms 90 % of all people live north of the equator. Reasons? About 2/3 of the population live within 300 miles of the ocean. Also, more than half the people live on 5% of the land. Sparsely populated regions Sparsely populated regions People generally avoid:People generally avoid: Dry lands Dry lands Wet lands Wet lands Cold lands Cold lands High lands High lands The EcumeneThe Ecumene The portion of the Earths surface occupied by permanent human settlementThe portion of the Earths surface occupied by permanent human settlement The Ecumene has increased over time. Why?The Ecumene has increased over time. Why? China = China = 1,336,718,015 India = 1,189,172,906 U.S.= 313,232,044 Indonesia= 245,613,043 Brazil = 203,429,773 Pakistan= Pakistan= 187,342,721 Bangladesh= Bangladesh= 158,570,535 Nigeria= Nigeria= 155,215,573 Russia= Russia= 138,739,892 Japan= Japan= 126,475,664 Illustrate Population Growth with IKEA binss_rosling_on_ global_populat ion_growth.ht ml What is Roslings hypothesis for population growth in the future? Do you agree? Why/ Why not? What will slow excessive population growth? Can you guess the time these were made? Can you guess the time these were made?
