To complete this paper, answer the questions below.



  1. Explain why these graphs are histograms by describing the variable on the y axis, units used, what the markings are for, and what is being measured on the x axis. Note that these density population graphs are standing on end and each one is two graphs side by side (one for males and one for females) sharing the same x axis.

  2. Describe the shape, center, and spread of the U.S. population’s age in 1970 and then in 2020.

  3. What story does each graph tell you about age distribution in 1970 and 2020?

  4. What social, medical, and public health changes have occurred in the last 50 years to explain the difference in the age distribution of the United States?


References are not required. The point of this paper is to show how well you understand how to read a graph. However, if you do provide information from a published resource, be sure to cite and reference it.

US and Graph
Answer 1
The y-axis measures the age of American males and females in ten-year increments, from zero to 100. The populace of American women and men is measured in five million increments along the x-axis.
Answer 2
The graph for the 1970s has the appearance of a triangle. In this graph, the older ages are significantly smaller compared to the younger ages at the bottom. All ages are more distributed equally in the 2020s compared to their distribution in the 1970s, resulting in a bell-shaped pattern. The graph is considerably larger in the 2020s than in 1970 to represent the expanding human population.
Answer 3
Compared to the 1970s, the growth of older populations is accelerating. Since the 1970s, the global population has also expanded...
