Population Pyramids

Question 1

Population Pyramid

Answer 1

A graphical representation of a population’s age and gender structure, providing insights into birth rates, death rates, and overall demographic trends.

Question 2

Age Cohort

Answer 2

A group of individuals in a population who share the same age range, typically represented on a population pyramid in five-year intervals.

Question 3

Cohort

Answer 3

A group of individuals who share a common characteristic or experience, often used in population pyramids to represent age groups.

Question 4

Dependency Ratio

Answer 4

The ratio of the economically dependent population (young and elderly) to the economically productive population (working-age), providing insights into the economic challenges a society might face.

Question 5

Expansive Population Pyramid

Answer 5

A population pyramid with a broad base, indicating a high birth rate and a large proportion of young people. It often suggests a population with potential for future growth.

Question 6

Constrictive Population Pyramid

Answer 6

A population pyramid with a narrow base, indicating a low birth rate and a smaller proportion of young people. It may suggest a declining population.

Question 7

Stationary Population Pyramid

Answer 7

A population pyramid with relatively equal proportions across age groups, indicating a stable population with consistent birth and death rates.

Question 8

Youthful Population Pyramid

Answer 8

A population pyramid with a significant youth population and a broad base, suggesting a high birth rate and potential for future growth.

Question 9

Ageing Population Pyramid

Answer 9

A population pyramid with a higher proportion of elderly individuals, indicating a declining birth rate and longer life expectancy.

Question 10

Population Momentum

Answer 10

The tendency for a population to continue growing despite a reduction in birth rates. This occurs due to the large number of individuals in the childbearing age group.

Question 11

Rapid Growth Phase

Answer 11

The stage of a population pyramid characterized by a broad base, indicating a high birth rate and significant population growth potential.

Question 12

Stable Growth Phase

Answer 12

The stage of a population pyramid where birth and death rates are more balanced, resulting in a steady and stable population growth.

Question 13

Declining Growth Phase

Answer 13

The stage of a population pyramid characterized by a narrowing base, indicating a declining birth rate and potential population decline.

Question 14

Baby Boom Generation

Answer 14

A demographic cohort born during a period of significantly increased birth rates, often following a war or economic prosperity.

Question 15

Echo Boom Generation

Answer 15

A demographic cohort born to the Baby Boom generation, resulting in a “boom” or increased birth rate in the subsequent generation.

Question 16

Sex Ratio

Answer 16

The ratio of males to females in a population, often expressed as the number of males per 100 females.

Question 17

Population Inversion

Answer 17

A phenomenon where the elderly population of an area exceeds the number of younger individuals, leading to a top-heavy population pyramid.

Question 18

Implications of Population Pyramids on Services

Answer 18

Population pyramids can inform the planning of services such as education, healthcare, and social welfare by highlighting the needs of specific age groups.

Question 19

Demographic Dividend

Answer 19

The economic benefit that arises when a large proportion of a population is in the working-age group, contributing to economic growth.

Question 20

Population Pyramids and Policy Planning

Answer 20

Governments and policymakers use population pyramids to develop strategies for healthcare, education, and social welfare, considering the age structure and demographic trends.
