The data is from the website the questions is asking for. I attached it as best as I could on the document so you can see it. I have other images of it as well. It's based on Population of Five Age group. First data is US and the second is from the Afghanistan. It's asking for a dependency ratio.

2. Once at this site, click the tab "Select Report" and then choose "Population by Five Year Age Groups". Select the year "2020" and "United States." Then select the submit tab. With the resulting data, calculate the dependency ratio. Repeat these steps for Afghanistan. Discuss potential reasons for differences in the results.
