Countries where mental health problems are most prevalent

An international survey tracking mental health prevalence among adults (18-64 years old) reveals significant global variations in reported symptoms.

Data gathered between July 2024 and June 2025 shows Australia topping the list, with 43% of respondents reporting experiencing mental health problems in the preceding twelve months.

The USA follows closely at 41%, with the United Kingdom (38%) and Canada (37%) also showing high rates of self-reported issues. The data suggest that mental health challenges are substantially prevalent across multiple developed Western nations.

Further down the ranking, Germany and Brazil reported rates of 32% and 29%, respectively. By contrast, several large Asian nations appear to have lower rates, with India (23%), Japan (21%), and China (14%) reporting the lowest shares among the countries surveyed.

The figures represent the share of people in each country who experienced symptoms of mental health problems within the timeframe.
