One in five Hong Kong families felt unhappy, with mothers suffering more than fathers, while the overall happiness index of households dropped this year because of the city’s fifth Covid-19 wave, a survey revealed on Thursday.

The survey, launched by the happiness advocacy platform HK.WeCARE of Wofoo Social Enterprises and Lee Kum Kee Family Foundation, interviewed a total of 1,633 people via online questionnaires between March and April this year, and found 81.1 per cent of them scored six and above on a scale of zero to 10 on family happiness.
