The EVA study says that there are over 50,000 men who should be in their best working years (25–54) who do not have jobs and who are not actively seeking jobs. This does not include men who are studying or who are on disability pensions. The authors of the labour market analysis refer to this group as “the lost workmen”. In statistics, they fall under the category of “others not in the workforce”. In addition, there are over 28,000 unemployed men in the same age group who are looking for jobs, but are unlikely to ever return to the workforce. Even while unemployment levels decline, the numbers of lost workmen have grown steadily over the past few years.
