Finland has significant timber, mineral (iron, chromium, copper, nickel, and gold), and freshwater resources. Forestry, paper factories, and the agricultural sector (on which taxpayers spend around €3 billion annually) are important for rural residents so any policy changes affecting these sectors are politically sensitive for politicians dependent on rural votes. The Greater Helsinki area generates around one third of Finland's GDP. In a 2004 OECD comparison, high-technology manufacturing in Finland ranked second largest after Ireland. Knowledge-intensive services have also resulted in the smallest and slow-growth sectors – especially agriculture and low-technology manufacturing – being ranked the second largest after Ireland.
