Final answer:
A Population Pyramid is the specific type of bar graph that represents the number or percentage of men and women in different age brackets for a given population, showing comparative data for both genders.
Step-by-step explanation:
The type of bar graph or histogram that depicts the number or percentage of men and women in certain age brackets in a given population is best described as a Population Pyramid. This visual representation is typically back-to-back, with men on one side and women on the other, divided into various age brackets. As a way to visualize age distribution, a Population Pyramid can reveal a wealth of information, such as the relative sizes of age groups, potential dependency ratios, and provide insight into the demographic history and future of the population.
Although the terms histogram, bar chart, and pie chart can describe different methods of representing data visually, none of these specifically represent the distribution of age and sex in a population like a Population Pyramid does. These different representations—bars showing total population divided into percentages, shaded areas within a single bar for different age groups, and the use of percentages rather than numbers—are all useful techniques for showing data, depending on the intended focus and the type of information that needs to be communicated.
