D Correct answer
Explanation

Population pyramids can be used to make predictions about the future of a population, including the size of the population, the age distribution of the population, and the sex distribution of the population.

Multiple choice

  1. They can only be used to describe the age and sex distribution of a population

  2. They cannot be used to make predictions about the future of a population

  3. They do not take into account the effects of migration

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Population pyramids have a number of limitations, including the fact that they can only be used to describe the age and sex distribution of a population, they cannot be used to make predictions about the future of a population, and they do not take into account the effects of migration.

Multiple choice

What are some of the uses of population pyramids?

  1. To identify trends in the age and sex distribution of a population

  2. To compare the age and sex distribution of two or more populations

  3. To make predictions about the future of a population

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Population pyramids can be used to identify trends in the age and sex distribution of a population, compare the age and sex distribution of two or more populations, and make predictions about the future of a population.

Multiple choice

How can population pyramids be used to inform policy decisions?

  1. To identify areas where there is a need for more investment in education and healthcare

  2. To identify areas where there is a need for more affordable housing

  3. To identify areas where there is a need for more jobs

  4. All of the above
