There were 25,000 names contained in the data leak, including Afghans who claimed to have assisted the UK and their family members.
If wider family are included, the number affected is about 100,000, the UK government has said.
Approximately 6,900 of them have been brought to the UK, are in transit or are set to travel under the secret Afghan Response Route that was revealed on Tuesday.
A further 17,000 affected by the data breach are coming via the other publicly known schemes for Afghan relocation. The MoD says all but 1,000 of these people would have come to the UK anyway.
That suggests that the total coming explicitly because of the breach — either via the secret or public routes — amounts to about 7,900.
