A worrying trend

The yellow line is 2010. As one can see, there has been a clear trend in previous years – that net departures peak in January and decline during the year.

But in 2010, the number of net departures is slightly increasing. Now 2009 was a lot lower than 2007 or 2008, so it is coming off a lower base, but I’d be concerned if that trend continues for much longer.
