population pyramid
birth rate
The correct answer is population pyramid.
The demographic factor that is commonly used to examine change in the total population over time is the population pyramid. To determine this, one can look at the responses provided and analyze them one by one:
1. Birth rate: While birth rate is indeed a demographic factor, it measures the number of births per 1,000 people in a population per year. It does not directly reflect changes in the total population over time.
2. Industrial Revolution: The Industrial Revolution is a historical event that took place during the 18th and 19th centuries, and it is not a demographic factor used to examine changes in the total population.
3. Race/ethnicity: While race/ethnicity is an important demographic factor, it does not directly measure changes in the total population over time. Instead, it focuses on characteristics related to cultural, ethnic, or racial background.
4. Population pyramid: A population pyramid is a graphical representation of a population's age and sex distribution. It depicts the number or percentage of males and females within different age groups. By analyzing changes in the shape and structure of a population pyramid over time, one can examine the changes in the total population size and age distribution.
Therefore, among the given options, the population pyramid is the example of a demographic factor that is commonly used to examine changes in the total population over time.
