The following three charts show the happiness score by country by age group (11, 13 and 15 year olds).
Happiness tends to decrease with age. It’s something every mom already knows that an 11 year old seems to be more content than a 15 year old. This trend is being observed across virtually all researched countries. Girls tend to be happier at age 11 then boys, but then drop 10 points in almost half of the countries by age 15. The downward age move for boys is less significant.
Another interesting observation is that boys age 15 are happier than girls age 15. However, in general gender differences were not large for ages 11 and 13, and were only significant at age 15 in a few countries, such as Romania, Poland, Sweden, and England. For the United States the high happiness of 15 year old boys was 85% versus 81% for girls.
The map shows the satisfaction of 15 year old teenage boys. The companion chart for girls can be found in the first part of this blog.
