The indicator depicts the number of people receiving disability pension from the earnings-related pension scheme according to the main disease category. The categorization is based on the main reason for the disability. The disease codes are based on the international ICD-10 disease categorization. Disability pensions include the actual disability pension as well as individual early retirement pensions, which were discontinued in 2011. Actual disability pensions are granted either until further notice or as cash rehabilitation benefit for a set period of time. Both can be granted in the form of a full pension (work ability decreased by at least 3/5) or a partial pension (work ability decreased by 2/5–3/5).
A disability pension may be granted to a person aged 18-62 years. The pension is granted in the form of an old-age pension if the disability begins after the person has turned 63 years.
