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 specific differences in each country, there was a strong link between unemployment and suicide rates in all four regions. The study found that changes in unemployment rates affected both genders and different age groups equally. Following the 2008 crisis, there was a short-term increase of 5,000 suicides, totaling 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. The researchers recommend investing in programs that help people enter the job market and foster a healthy work environment, particularly in countries with lower unemployment rates. These findings suggest that suicide prevention strategies should focus on the negative health effects of unemployment during both economic stability and recession. The study was published in The Lancet Psychiatry.
