The Recruitment Trends report has analysed, in a lot of detail, what really happened in online recruitment during 2010. It includes reporting on the key trends in vacancy volumes, application volumes, as well as salary levels across a wide range of industry sectors.
If you connect with their Facebook page you'll also get access to additional, mostly statistical, information on an on going basis.
I’m curious if you happen to know where I could obtain similar information for the USA?
You need to contact the Bureau of Labor Statistics which is based in Washington DC. They have a website which contains literally thousands of pieces of information.
Hope this helps
