The United States is by far the largest market, accounting for about 30% of the global turnover for temporary agency work. However, Europe is the largest region with nine of the largest markets (in terms of turnover) in the top 15. At €129bn, the total turnover of the nine European countries is higher than the €107bn in the United States. The importance of temporary agency work differs considerably within Europe. The Netherlands, the United Kingdom and France have the highest penetration rates of agency work in the European Union.
