2History of Human Settlement People lived nomadic lifestyles.Agriculture caused people to settle in areas near water.Nile Valley, Mesopotamia, Indus Valley, Huang He Valley

4Human Factors Affecting Settlement Political and Economic Centers: People move to areas of political or economic importance, such as capital cities.Transportation Routes: People often settle along transportation routes, such as coastlines, rivers, canals, railroad lines, or roads.
5Human Factors Affecting Settlement Cont’d Technology: Improvements in technology can expand areas of settlement.Urbanization: Since the start of the Industrial Revolution, urbanization (people moving from the countryside to cities) has increased greatly.

10Population Density Maps A map showing how many people live per square mile in a given area.It shows the distribution of population in that area.
11Population Density Maps Uses dots to indicate the location of major towns and cities.Dots are also used to show the concentration of where people live.
12Population PyramidsThese compare the numbers of males and females in a particular country.Stacked bars indicate the number of people for each age group.They are used by demographers to show the age distribution in a society.

14Trends in World Population Growth Cont’d European Colonization: As Europeans colonized new areas, they spread new farming methods and modern medicine.Current Trends:Population growth has greatly accelerated.China, India, and Africa are struggling to reduce birth rates to bring population under control.
