Match population pyramid type with countries

1.	Expanding Populations	A.	Japan
2.	Constant Population	B.	Nigeria
3.	Declining Populations	C.	Australia

The correct answer is 1-B, 2-C, 3-A.

Key Points

• Expanding populations refer to countries with a high birth rate and a rapidly growing population. Nigeria is an example of such a country, characterized by a broad base in its population pyramid, indicating a large number of young people.
• Constant populations are typical in countries where the birth rate and death rate are roughly equal, leading to a stable population size. Australia represents this type of population pyramid, where the shape is more rectangular, indicating balanced age distribution.
• Declining populations are seen in countries with a low birth rate and an aging population. Japan is an example, where the pyramid is narrower at the base and wider at the top, indicating a higher proportion of older individuals.

 Additional Information

• Expanding Populations
  • Countries with expanding populations typically have high fertility rates and a significant proportion of the population in the younger age groups.
  • These countries often face challenges related to education, healthcare, and employment for their rapidly growing population.
• Constant Population
  • Countries with constant populations have a balanced age structure, with similar numbers of people in each age group.
  • This type of population pyramid is often found in developed countries where both birth rates and death rates are low.
• Declining Populations
  • In countries with declining populations, there are fewer young people and a larger proportion of elderly individuals.
  • These countries may face challenges related to pension systems, healthcare for the elderly, and a shrinking workforce.
