2) Population Pyramids a) b) c) d) e) What does the vertical axis on the population pyramid represent? _____________________ What type of population pyramid is indicative of a lesser developed country? _________________ What does a narrow base to the population pyramid indicate? ________________________ What type of population pyramid has a triangular shape? __________________________ What type of population pyramid is wider at the reproductive age than at the pre­reproductive ages. _____________________________________________ f) ____________________________ are graphs that show the age structure of a population by age & gender. g) What type of population pyramid is depicted below? __________________________ h) What characteristic of this population pyramid indicate its high death rate? ___________________
i) Is the population pyramid for Afghanistan stationary or expansive? _________________________ j) Which stage of the DTM is Afghanistan in? ______________________________________ k) Which stage of the DTM is Belgium in? _____________________ Give two pieces of evidence to support your answer. ____________________________________________________________________ 3) a) Pakistan has 41% of its population less than 15, and 4% over 65. This makes 55% (100 ­ (41+4)) between the ages of 15 and 64. What is the dependency ratio? b) New Zealand has 23% of its population less than 15, and 12% over 65. This makes 65% between 15 and 64. What is the dependency ratio? 4) Calculate the population density for the following countries:
Total Land
Area (km2)

988 700 000
1001 000
32 650
68 360 000
