The reason I ask is because it's common for outlets to post figures about a particular type of channel crossing in isolation, creating an impression that the increase is far greater than it is. From what I've heard, there was a huge crackdown on certain types of crossing and increases in security around cargo lorries, pushing people towards using these boats instead.
But according to this, there has been an overall increase too...
First one is applications.
Second one is successful applications.
But yeah, the increase from hundreds to tens of thousands is just in one particular method of channel crossing by the looks of things.
