Population
  1. Population distribution
    1. The way in which people are spread across a given area
      1. Different scales
        1. Local
          1. Regional
            1. National
              1. Global
              2. Tends to be uneven
                1. Population density
                  1. Average number of people per square kilometre
                    1. Way of measuring population distribution
                      1. Shows weather an area is densely or sparsely populated
                      2. The population density of a country has little to do with its level of economic development
                        1. Bangladesh = LEDC = densely populated
                          1. Japan = MEDC = densely populated
                            1. The majority of places with high population densitites are in the Northern hemisphere
                              1. Areas of densely or sparsely population are spread unevenly across the world
                            2. Factors affecting population density
                              1. Attract
                                1. Temperate climate
                                  1. Low lying land
                                    1. Fertile land
                                    2. Good supplies of natural resources
                                    3. Discourage

                                          2. Dense vegetation

                                        1. Steady growth until the 1800's
                                          1. In 1820 the world's population reached 1 billion
                                            1. In the early 1970's the world's population reached 3 billion
                                              1. In 1999 the world's population doubled to 6 billion
                                                1. Global rate of population growth is now 1 billion every 15 years
                                          2. Population Pyramids
                                            1. Show structure of population
                                              1. Compares relative numbers of people in different age groups

                                                      1. The difference between the birth and death rates is called the natural increase
                                                        1. Subtract death rate from birth rate
                                                        2. Population will increase if birth rates are higher than death rates
                                                          1. LEDCs have high growth rates
                                                            1. Both birth rates and death rates tend to be high
