Geography: Population: 4 of 7




     •   Sparsely Populated – Places which contain few people per km sq.
     •   Densely populated – Places which contain many people per km sq.
     •   Population density – The number of people per km sq.












                                                                                                               Stages of the DTM
                                                                                   Stage 1: Limited medical care + poor diet = high infant mortality.

                                                                                   •    Strong religious values = high birth rate. Example: Indigenous Tribes in the Amazon
                                                                                        Rainforest.
                                                                                   Stage 2: Increase in access to basic medical care = decreased infant mortality and death rate.


                                                                                   •    Diets also improved. Birth rate remains high as children are needed to work on farms.
                                                                                   •    Birth rate also remains high as religion plays a significant role in society. Example:
                                                                                        Afghanistan.
         Factors affecting Population Density                                      Stage 3: Decrease in birth rate as women are able to access education.
         Human = Red
         Physical = Black                                                          •    Decrease in birth rate as religion loses importance in society and contraception
                                                                                        becomes available.

                Densely Populated              Sparsely Populated                  •    Death rate continues to decline due to improvements in diet, healthcare and physical
                                                                                        fitness.
                 Pleasant climate                  Steep slopes                    •    Total population continues to increase as there is natural increase. Example: India.
                                                                                   Stage 4: Birth rate remains low and fluctuating as women put careers before having children.
                    Fertile soil                    Poor soils
                                                                                   •    Death rate remains low due to improvements in healthcare, diet and physical fitness.
            Access to infrastructure and   Lack of access to infrastructure
                     services                                                      •    Total population reaches its peak and begins to fall. Example: The UK.
             Access to high paying jobs      Low paying, low skill jobs            Stage 5: Death rate is greater than birth rate = natural decrease.

                                                                                   •    Ageing population due to improvements in healthcare, diet and physical fitness.

                                                                                   •    Children are expensive so birth rates continue to fall.
