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. Data was not available from India or China. Lead author Carlos Nordt from the University of Zurich stated that despite country-specific differences, a strong correlation between unemployment and suicide rates was found in all four regions. The study showed that changes in unemployment rates affected both genders and various age groups equally. Nordt noted that there was a short-term increase of 5,000 suicides after the 2008 crisis, with a total of around 46,000 suicides associated with unemployment that year. The impact of unemployment on suicide was more significant in countries with lower pre-crisis unemployment rates. Therefore, the researchers suggest investing in programs that help integrate individuals into the job market and create a healthy work environment, especially in countries with lower unemployment rates. These findings indicate the need for suicide prevention strategies that address the negative health impacts of unemployment in both stable economic times and during recessions. The study was published in The Lancet Psychiatry.
