Which of the following is an example of a demographic factor that is commonly used to examine change in total population over time? (1 point) Responses race/ethnicity race/ethnicity population pyramid population pyramid birth rate birth rate Industrial Revolution Industrial Revolution

population pyramid

The correct answer is "population pyramid." A population pyramid is a graphical representation that shows the distribution of various age groups in a population. It is commonly used to examine changes in the total population over time, providing insights into birth rates, death rates, and other demographic factors. The options "race/ethnicity" and "birth rate" are also demographic factors, but they do not specifically focus on examining change in total population over time. The option "Industrial Revolution" is not a demographic factor but rather a historical event.

The demographic factor commonly used to examine change in total population over time is the population pyramid. To understand why this is the case, let's break down the options you provided:

1. Responses race/ethnicity: While race and ethnicity can provide insights into population characteristics, they do not directly show changes in total population over time.

2. Population pyramid: This is the correct answer. A population pyramid is a graphical representation that displays the distribution of various age groups in a population at a given point in time. By comparing population pyramids across different years, you can observe changes in the distribution of age groups and determine if the total population has increased, decreased, or remained stable.

3. Birth rate: Birth rate represents the number of births per 1,000 individuals in a population per year. While birth rate can be used to analyze population growth, it does not directly indicate changes in total population over time.

4. Industrial Revolution: The Industrial Revolution refers to a period of significant industrialization, technological advancements, and social changes that occurred in the 18th and 19th centuries. Although it had a profound impact on population growth, it is not a demographic factor used to examine changes in total population over time.

In conclusion, the correct option is "population pyramid" as it provides a visual representation of age distribution and allows for the examination of changes in total population over time.
