The countries were categorized into four regions: North and South America, northern and western Europe, southern and eastern Europe, and Non-Americas and non-Europe. No data was available from India or China. Lead author Carlos Nordt from the University of Zurich stated that there was a strong link between unemployment and suicide rates in all four regions, despite country-specific differences. The study revealed that changes in unemployment rates affected both genders and age groups equally. After the crisis in 2008, there was a short-term increase of 5,000 suicides, totaling around 46,000 suicides associated with unemployment that year. The impact of unemployment on suicide was greater in countries with lower pre-crisis unemployment rates. The researchers recommended investments in programs that help people find jobs and promote a healthy work environment, even in countries with lower unemployment rates. The findings suggest that suicide prevention strategies should focus on the negative health effects of unemployment during times of economic stability and recession. The study was published in The Lancet Psychiatry journal.
