Feeling of loneliness among adults 2021, by country

According to a global survey, about 33 percent of adults experienced feelings of loneliness worldwide. Brazil had the highest percentage of people experiencing this, with 50 percent of respondents declaring that they felt lonely either often, always, or sometimes. Turkey, India, and Saudi Arabia followed, with 43 percent to 46 percent of respondents having experienced loneliness at least sometimes. On the contrary, the Netherlands, Japan, Germany, and Russia registered the largest share of interviewees which did not feel lonely.

Coping with loneliness during the pandemic

The COVID-19 pandemic has suddenly cut off people from all over the world from their social life, and the lack of companionship has been a difficult situation for many to cope with. In the United States, people who experienced lack of company were, unsurprisingly, individuals living alone, and unemployed, disabled, or unemployed people. In relation to mental health, Americans who reported more symptoms of depression were by far more likely to feel lonely.

Impact of mental health

According to a survey conducted in 2021 among G7 countries, about seven in 10 people experienced a worsening of their psychological health during the pandemic. A study on clinician-reported changes in selected health behaviors in the United States showed that during the pandemic patients have suffered more from feelings of loneliness, depression or anxiety, and burnout. Also nutrition and other habits have been impacted. The study reported an increase in alcohol consumption, smoking cigarettes, poor nutrition, and use of other substances.
