Question

Population pyramid showing predicted population statistics for an unnamed country. The map shows population data for the male and female population from the 0 to 4 cohort to the 100 plus cohort. The pyramid shows the following statistics for the male population, 0 to 4 cohort, 30.5 million, 5 to 9, 31.0 million, 10 to 14, 30.6 million, 15 to 19, 30.4 million, 20 to 24, 31.9 million, 25 to 29, 35.4 million, 30 to 34, 39.3 million, 35 to 39, 40.9 million, 40 to 44, 38.5 million, 45 to 49, 38.0 million, 50 to 54, 43.0 million, 55 to 59, 49.2 million, 60 to 64, 55.8 million, 65 to 69, 42.0 million, 70 to 74, 34.6 million, 75 to 79, 35.0 million, 80 to 84, 26.5 million, 85 to 89, 12.9 million, 90 to 94, 3.9 million, 95 to 99, 1.1 million, 100 plus, 120,000. The pyramid shows the following statistics for the female population, 0 to 4 cohort, 28.6 million, 5 to 9, 29.0 million, 10 to 14, 28.6 million, 15 to 19, 28.5 million, 20 to 24, 30.1 million, 25 to 29, 33.7 million, 30 to 34, 36.9 million, 35 to 39, 37.2 million, 40 to 44, 34.1 million, 45 to 49, 33.2 million, 50 to 54, 38.4 million, 55 to 59, 46.1 million, 60 to 64, 54.9 million, 65 to 69, 43.5 million, 70 to 74, 37.9 million, 75 to 79, 41.6 million, 80 to 84, 35.6 million, 85 to 89, 20.9 million, 90 to 94, 8.4 million, 95 to 99, 3.4 million.

The population pyramids above show two countries with differing rates of population growth.


A. Compare the growth characteristics of Country 1 and Country 2.
B. Explain how EACH country's population growth relates to the Demographic Transition Model.
C. Identify and explain ONE potential advantage associated with the population structure of each country.
D. Identify and explain ONE potential disadvantage associated with the population structure of each country.
E. Explain what information about populations cannot be gathered when looking solely at population pyramid data.

Answer 1

A. Country 1 has a rapidly growing population as seen by the wide base of the pyramid, with the largest age group being in the 20-29 age range. Country 2 has a more stable population with a smaller base and consistent width throughout the pyramid, indicating a more even distribution across age groups.

B. Country 1's population growth is indicative of Stage 2 of the Demographic Transition Model, where high birth and death rates result in rapid population growth. Country 2's stable population is more closely aligned with Stage 4, where low birth and death rates result in a stable population size.

C. One potential advantage of Country 1's population structure is the potential for a large workforce and increased economic growth. With a large population of young adults, there may be more individuals available to enter the workforce and contribute to the economy.

D. One potential disadvantage of Country 1's population structure is the strain on resources such as healthcare, education, and housing. With a rapidly growing population, there may be inadequate resources to support the high demand for services.

For Country 2, one potential advantage of a stable population structure is the potential for long-term planning and stability. With a consistent distribution across age groups, there may be more predictability in terms of future population needs and resource allocation.

A potential disadvantage of Country 2's population structure is the potential for a shrinking workforce and aging population, which may result in a decrease in economic growth and an increasing burden on healthcare and social security systems.

E. Population pyramid data does not provide information about key demographic characteristics such as race, ethnicity, religion, or income level. It also does not provide information about migration patterns or fertility rates.
