the percentage of the cause of stress for different age groups in Canada

The bar chart compares the percentage of the cause of stress for different age groups in Canada.
Looking at information for more details, we can see the most important causes of stress at age 75 and over with no particular reason. By contrast, the reason for working too much recorded the lowest figure.
The figures no particular reason were nearly two times as high as a reason for their health problems. For example, the number of people who have this stress was 10 percent at the age between 55 and 64. But the figures for age 75 and over were approximately double for the same reason.
The percentage was increased dramatically at the highest percent for no reason. The stress by working too much was even less likely to experience problems which were 3 percent for this reason.
