Human Population Growth Quiz

1. What is a key factor influencing human population growth?

The number of cars in a population

The fertility rate in a population

The color of people’s hair

The number of buildings in a population

The fertility rate, or the average number of children a woman gives birth to in her lifetime, is a key factor influencing human population growth. Higher fertility rates lead to faster population growth.

Explanation

The fertility rate, or the average number of children a woman gives birth to in her lifetime, is a key factor influencing human population growth. Higher fertility rates lead to faster population growth.

2. What is the scientific discipline that studies human population called?

Exponential growth

Demography

Logistic

Demographic Transition

Demography is the scientific study of human populations, including their sizes, compositions, distributions, densities, growth, and other characteristics, as well as the causes and consequences of changes in these factors.

Explanation

Demography is the scientific study of human populations, including their sizes, compositions, distributions, densities, growth, and other characteristics, as well as the causes and consequences of changes in these factors.

3. What is the term for the number of individuals per unit area or volume?

Mortality rate

Fertility rate

Birth rate

Population density

Population density refers to the number of individuals per unit area or volume. It is a key factor in understanding population dynamics as it can influence social structure, communication, and disease transmission in populations.

Explanation

Population density refers to the number of individuals per unit area or volume. It is a key factor in understanding population dynamics as it can influence social structure, communication, and disease transmission in populations.

4. What is a population pyramid?

A pyramid made of population data

A pyramid made of people

A graphical representation of the age and sex distribution of a population

A pyramid used in population genetics

A population pyramid, also known as an age-structure diagram, is a graphical representation of the age and sex distribution of a population. It is used by demographers to study the distribution of ages in a population, which is critical for predicting future population growth.

Explanation

A population pyramid, also known as an age-structure diagram, is a graphical representation of the age and sex distribution of a population. It is used by demographers to study the distribution of ages in a population, which is critical for predicting future population growth.

5. How is human population growth typically measured?

By counting every individual in a population

By estimating the number of individuals in a population

By measuring the size of the area occupied by a population

By calculating the rate of natural increase or net migration

Human population growth refers to the increase in the number of individuals in a population over time, typically measured as a rate of natural increase from births and deaths, or net migration.

Explanation

Human population growth refers to the increase in the number of individuals in a population over time, typically measured as a rate of natural increase from births and deaths, or net migration.

6. Like the populations of many other living organisms , the size of the human population tends to _____ with time.

The size of the human population, like many other living organisms, tends to increase over time, primarily due to birth rates exceeding death rates, but also due to factors like technological advancements and improved healthcare.

Explanation

The size of the human population, like many other living organisms, tends to increase over time, primarily due to birth rates exceeding death rates, but also due to factors like technological advancements and improved healthcare.

7. What models do demographers use to predict future population growth?

Density-dependant diagrams

Population density

Immigration

Age- structure diagrams

Age-structure diagrams (also known as population pyramids) are graphical representations of the age and sex distribution within a population. They are used by demographers to study the distribution of ages in a population, which is critical for predicting future population growth.

Age-structure diagrams (also known as population pyramids) are graphical representations of the age and sex distribution within a population. They are used by demographers to study the distribution of ages in a population, which is critical for predicting future population growth.

8. What is the most likely future trend of human population growth?

Greatly Increase

Increase

Level off or even decrease

Level off or even increase

Most demographers predict that global human population growth will level off and could even decrease in the future due to declining fertility rates and aging populations, especially in developed countries.

Explanation

Most demographers predict that global human population growth will level off and could even decrease in the future due to declining fertility rates and aging populations, especially in developed countries.

9. What is the phenomenon where the population size of a species fluctuates in response to environmental conditions?

Population cycle

Demographic transition

Immigration

Age structure

A population cycle refers to a phenomenon where the population size of a species fluctuates in a cyclical manner due to environmental conditions. This is commonly seen in some animal populations, such as the snowshoe hare and lynx, where their population sizes oscillate over time due to predator-prey dynamics.

This is commonly seen in some animal populations, such as the snowshoe hare and lynx, where their population sizes oscillate over time due to predator-prey dynamics.

10. When is the demographic transition considered complete?

Birth rate is greater than the death rate.

Population growth stops.

Death rate begins to fall.

Death rate is greater than the birthrate

The demographic transition is considered complete when the population growth stops, which typically happens when both birth rates and death rates are low, stabilizing the population.

Explanation

The demographic transition is considered complete when the population growth stops, which typically happens when both birth rates and death rates are low, stabilizing the population.
