Gallup’s Global Emotions Report reveals the status of positivity and negativity worldwide.

People around the world are becoming more angry, stressed, and worried.

A third of people around the world say they suffer from stress, while at least one in five experience sadness or anger on a regular basis, according to a Gallup survey which interviewed 150,000 people in over 140 countries.

The annual Gallup Global Emotions Report asked people about their positive and negative experiences.

According to the study, the most negative country in the world was Chad while the most positive was Paraguay.

Ranking worldwide

The U.S. ranked as the 39th most positive country, the UK 46th, and India 93rd in the report.

Respondents were asked questions such as “did you smile or laugh a lot yesterday?” and “were you treated with respect?” in a bid to gain an insight into people’s daily experiences.

Around 71% of people said they experienced a “considerable” amount of enjoyment the day before they answered the survey.

Yet the poll also found that levels of stress were at a new high, while levels of worry and sadness had also increased. Some 39% of those polled said they had been worried the day before the survey, while 35% were stressed.

Latin American countries, including Paraguay and Mexico, topped the list of positive experiences, where people reported “feeling a lot of positive emotions each day.”

Chad had the highest score for negative experiences. More than seven in 10 Chadians said they had struggled to afford food at some point in the past year.

Nevertheless, according to the results of the survey, people in the U.S. and Greece were more stressed than Chadians.

Greece had the most stressed population in the world with 59% of adults saying they experienced stress the day before they responded to the poll in comparison to 55% in the U.S.
