Average gross income for those 65 and over: $44,132
Average gross income for the 65-and-over population in Finland was $44,132 in 2012, over three times the global average.
Finland is home to one of the world's most comprehensive welfare systems that ensures its residents a high quality of living. Its elderly population – 18 percent of the country's 5.4 million residents according to government data – depends on that system, which includes a pension, care allowance, a housing allowance and a dependent child supplement.
With the government projecting seniors to account for 26 percent of the population by 2030 and nearly one third of the population by 2060, economic trouble may lie ahead.
In September 2012, the International Monetary Fund (IMF) warned that Finland's economy would likely suffer as its aging population begins to challenge its long-term growth potential. The IMF suggested that the government raise the minimum retirement age of 63 and tighten early-retirement plans to help offset rising health care costs.
