OECD Health Data 2007

Specialists now account for more than half of all physicians in most OECD countries, with the exceptions of Australia and Belgium, where GPs continue to outnumber specialists, and France, Portugal, New Zealand and Turkey, where their numbers are equal.

Income levels, a determining factor in the supply of doctors, vary a lot across OECD countries. Specialists generally earn substantially more than GPs, partially explaining the changing specialist/GP balance and the resulting concerns about GP shortages in several countries. Specialists’ incomes are high relative to average national income in the Netherlands, Belgium and the United States, but quite low in Hungary and the Czech Republic. GPs have high incomes (also in comparison with average national income) in the United States, New Zealand and the United Kingdom, and relatively low incomes in Hungary and the Czech Republic.
