The demographic factor commonly used to examine change in total population over time is the birth rate.

The demographic factor commonly used to examine change in total population over time is the birth rate. To determine which of the given options is an example of a demographic factor related to population change, we can consider each one:

1. Race/Ethnicity: While race/ethnicity is an important demographic factor, it does not directly measure change in total population over time. It focuses on the distribution of different racial and ethnic groups within a population.

2. Industrial Revolution: The Industrial Revolution refers to a historical phase, rather than a demographic factor. It signifies a period of significant technological advancements, social changes, and economic shifts during the late 18th and early 19th centuries.

3. Birth Rate: The birth rate measures the number of live births per 1,000 individuals in a population per year. It is a key demographic factor used to analyze changes in total population over time because it directly affects population growth. Higher birth rates lead to population growth, while lower birth rates contribute to population decline or slower growth.

4. Population Pyramid: A population pyramid is a graphical representation that displays the distribution of various age groups and genders within a population. While it can provide insights into population structure and demographic trends, it does not directly measure change in total population over time.

Therefore, the demographic factor of birth rate is the correct answer for the example of a factor commonly used to examine change in total population over time.
