Final answer:
The percent of the population represented by the shaded area is determined by analyzing the graph or statistical data provided. If the shaded region corresponds to a known percentage, we can directly infer that value; for example, if a shaded area matches a 62.4 percent area, it represents 62.4 percent of the population.
Step-by-step explanation:
To determine what percent of the population is represented by the shaded area, we would typically use the properties of the graph or statistical information provided. Using the given context, if the shaded region matches the red area in size, we analyze the red area's corresponding values to represent the percentage. For example, if the shaded blue area is equal to a red area representing 62.4 percent, then the blue shaded area also represents 62.4 percent of the population.
When reviewing a pie chart, remember that each slice corresponds to a part of the whole. In one example provided, the growing share of the U.S. population that is 65 and over can be observed through the size of the respective slice of the pie. Similarly, in other cases, a specific value such as the black-white segregation index tells us directly that 79 percent of a population would need to change location to achieve even racial distribution.
In every instance, interpreting the graphical representation accurately is crucial to understanding the underlying data regarding population percentages.
