We actually see less variation amongst age groups than we did between countries, with optimism levels falling between 80% and 86%. But we can see some signs of a trend. It looks like the young and the old are less optimistic than the middle-aged.
This makes sense. For the older population, health concerns are obviously severe. Meanwhile, the younger respondents are seeing their education, income, and job prospects put on hold. For the middle aged, who are more likely to have savings and own a home than those in the more youthful groups, things may not look so dire.
Going back to the falling optimism amongst the whole group, there are a few factors that may be at play. As we saw optimism levels fall, concerns about health and economical issues rose.
