Population Pyramids

1. Each graph does not have the largest percentage of population in the same age groups, except for Nigeria, total world, and less developed countries. Nigeria had the largest percentage of the population in the 0-4 age group, the U.S. had the largest percentage of the population in the 50-54 age group, Spain had the largest percentage of the population in the 35-39 age group, total world had the largest percentage of the population in the 0-4 age group, less developed countries had the largest percentage of the population in the 0-4 age group, and the more developed countries had the largest percentage of the population in the 45-49 age group.

2. Spain appears to have the slowest growth rate because the lowest percentage of their population is between 0 and 4 years old.

3. Nigeria.

4. Populations with high death rates and high birth rates would account for the pyramid shape of Nigeria’s population graph. Immigration rates are also most likely lower in Nigeria than they are in the U.S. and Spain.

5. Accessibility to doctors and medicine and differences in income levels could account for population differences between the regional population graphs.

6. You could document a correlation between these factors by seeing how the population distribution patterns change as the education and economic levels change. Also, you could compare the population distribution patterns of countries with similar education and economic levels.

7. Nigeria, because they have the highest percentage of population in the 0 to 4 age group.

8. The graph would even out into a column.

9. Women have a longer life expectancy, which would account for reason why they have a higher percentage within the population as the age range get older.

10. No, because the graphs only show the percentage of population, not the number of people in the population.

11. Pyramid-shaped graphs indicate a rapid growth in population because a large percentage of the population is young,...
