Of the 45,755 migrants who crossed the Channel by small boat last year, 215 have been deported.
More than 25,000 of those were found to be refugees, despite Government claims the majority of those crossing by small boat are economic migrants.
The figures, based off Home Office data, also show one in five channel migrants are children.
Last year saw record numbers arrive into Dover – 1,104 boats with an average of 41 people each day.
Data obtained through a Freedom of Information request showed just 0.47 per cent of the total migrant arrivals have been deported, including seven who were found to be criminals.
