Question

“Among those born in 1920, a woman in the lowest income group surviving to 50 could expect to live to age 80. A woman in the highest income group could expect to live to age 84. Use the chart below (and the 1^{st} chart, above) to compute the percentage difference [(final–initial)/initial*100% or change/initial*100%] for Life Expectancy at age 50 for women born in 1920 and 1940 for the top and bottom deciles.

Step 1

Given data of change in life expectancy at age 50 for women according to their income levels. As shown below

Among those born in 1920, a woman in the lowest income group surviving to 50 could expect to live to age 80. So life expectancy in 1920 for women = 80 in lowest income group

A woman in the highest income group could expect to live to age 84. So life expectancy in 1920 for women = 84 in highest income group.

Step 2

We need to determine percentage difference for life expectancy at age 50 for women born in 1920 and 1940 for top and bottom deciles.

The change in life expectancy at age 50 women from 1920 to 1940 is 0 for bottom decile from the chart shown below.

The life expectancy of 50 year...
