The proportion of young people describing themselves as "disengaged" from politics and "disgruntled" or angry has also grown significantly this year. At the same time, feelings of loneliness have increased, with only a third saying they find adequate support in their communities.

Well Told Story publishes a comic called Shujaaz and runs radio shows and websites aimed at helping young Kenyans find ways to make their lives better.
This year's Shujaaz360 survey found that one group of youngsters, dubbed 'hustlas', were weathering the economic and political storms better by being entrepreneurial and preparing for trouble.
"When they expect a pinch, hustlas plan for it and set aside more money than they would normally do, they save more. Their volatility is less than everyone else," said Mirzoyants-McKnight.
