Background Raising the statutory retirement age has been a common policy response to population ageing, but health problems may restrict labour force participation in older ages. We examined the development of healthy and unhealthy working life expectancies in Finland from 2000 to 2017 using different measures of health problems.

Methods Healthy and unhealthy working life expectancies were calculated for the age range 50–65 years using the Sullivan method. The health measures were limiting long-standing illness, self-rated health, mental health problems and self-assessed work ability.

Results Healthy working life expectancy was highest when health was measured by work ability. From 2000 to 2017, working years in full ability between the ages 50–65 increased from 6.2 (95% confidence interval 5.9–6.4) to 8.2 (8.0–8.5). Healthy working life expectancy increased also when measured by the other indicators. Unhealthy working years also increased, except when health problems were measured by limiting long-standing illness. The share of years in work increased both within the healthy and the unhealthy years, the increase being larger or equally large for the latter. Within the healthy and unhealthy years measured by the other three indicators, the share of working years increased irrespective of whether work ability was full or limited, but the increase was larger for limited work ability.

Conclusions In Finland, healthy working life expectancy has increased irrespective of how health is measured but also working with health problems has become more prevalent. The estimates for healthy working years are highest when a direct measure of work ability is used.
