There has been a slight increase or no change in welfare and health inequalities between population groups in the 21st century. Lifestyle-related diseases are on the rise. More than half a million Finns suffer from diabetes, type 1 diabetes being globally the most common in Finland. Many children are diagnosed with type 2 diabetes. The number of musculoskeletal diseases and cancers are increasing, although the cancer prognosis has improved. Allergies and dementia are also growing health problems in Finland. One of the most common reasons for work disability are due to mental disorders, in particular depression. Treatment for depression has improved and as a result the historically high suicide rates have declined to 13 per 100 000 in 2017, closer to the North European average. Suicide rates are still among the highest among developed countries in the OECD.
