Question

the figure shows projections of the age distribution of the u.s. population from 2010 through 2050, where the age groups increase from front to back. use this graph to answer the following questions. complete parts a through d. what percentage of the population was over age 65 in 2010? % (round to the nearest integer as needed.)

Explanation:

Step1: Analyze the graph for 2010 and >65 age group

Look at the 3D bar graph, find the bar for 2010 and the color corresponding to >65 (red). Estimate the percentage from the y - axis (percent of population). From the graph, the bar for >65 in 2010 seems to be around 13 - 14, but more accurately, by visual inspection, it's approximately 13% (or checking standard US population age distribution in 2010, the percentage of population over 65 in 2010 was about 13% (rounded to nearest integer)).

Step2: Round to nearest integer

The estimated percentage from the graph (or known data) for 2010, population over 65 is approximately 13% (when rounded to nearest integer).

Answer:

13
