Age Structure Diagrams

What does a Stable Growth Population Pyramid look like?

• A Stable Growth Population Pyramid has a wide base and a narrow top, indicating high birth rates and low life expectancy.

• A Stable Growth Population Pyramid has a more uniform shape, indicating that birth and death rates are relatively balanced, typical of industrialized countries.

• A Stable Growth Population Pyramid has a triangular shape, indicating a rapidly growing population.

• A Stable Growth Population Pyramid has a bell shape, indicating a declining population.

What does a population pyramid with a high dependency ratio suggest?

• A high dependency ratio indicates a balanced population structure with equal numbers of dependents and working-age individuals.

• A high dependency ratio suggests that there are many dependents (young and elderly) compared to the working-age population, which can impact economic productivity.

• A high dependency ratio means that the working-age population is larger than the dependent population.

• A high dependency ratio implies that the economy is thriving due to a larger workforce.

What is an Age Structure Diagram?

• A graphical representation showing the distribution of various age groups in a population, typically divided by gender.

• A chart that displays the economic status of a population.

• A map that illustrates the geographical distribution of a population.

• A diagram that outlines the historical events of a population.

What does a population pyramid with a wide top indicate?

• A high proportion of elderly individuals, suggesting an aging population and potential future challenges in care and support.

• A balanced age distribution, indicating a stable population growth.

• A high proportion of young individuals, suggesting a growing population.

• A declining population with fewer individuals in the working-age group.

What is the significance of the shape of a population pyramid?

• It indicates the economic status of a population.

• It provides insights into the growth trends, age distribution, and potential future demographic changes of a population.

• It shows the geographical distribution of a population.

• It reflects the cultural diversity within a population.

What does a population pyramid with a bulge in the middle indicate?

• A large cohort of individuals in that age range, often due to past high birth rates or immigration.

• A decrease in population due to high mortality rates.

• An even distribution of age groups across the population.

• A significant outflow of individuals from that age range.

How can migration affect the shape of a population pyramid?

• Migration has no effect on the population pyramid.

• Migration can lead to a more elderly population if older migrants are predominant.

• Migration can alter the shape of a population pyramid by increasing the population in certain age groups, often leading to a more youthful population if young migrants are predominant.

• Migration only affects the population size, not the age distribution.

What does a Declining Population Pyramid indicate?

• A population is experiencing a decrease in birth rates and an increase in death rates, leading to an aging population.

• A population is experiencing high birth rates and low death rates, leading to a youthful population.

• A population is stable with equal birth and death rates, maintaining its size.

• A population is experiencing rapid growth due to immigration and high birth rates.
