UK casualties in Afghanistan database FAQs
Details of UK troops killed in Afghanistan are being compiled by the BBC News website. This guide explains how the information is put together.
What sources are used?
Details of British casualties are released by the Ministry of Defence.
The MoD has a public record of the fatalities in Afghanistan which is routinely updated following a death.
In some cases, information may also come from other sources, such as contemporaneous BBC News stories, official reports, relatives' statements and inquests.
Why are some of the details incomplete?
If some of the information relating to a casualty has not been confirmed, the relevant space is left blank.
Following a fatality, the MoD often confirms only that somebody has died and, perhaps, some basic information such as the regiment and the place of the incident.
Further details, such as the name and birthplace of the person killed and a picture, are often released later.
The tables are updated as soon as possible after information becomes available.
What about figures for those wounded?
Details of those wounded in Afghanistan are not part of the BBC casualties database but the MoD publishes figures every two weeks.
Are insurgent or Taliban figures reported?
BBC Defence Correspondent Caroline Wyatt explains: "In our coverage of Afghanistan, we at BBC News do not generally report the numbers of Taliban or insurgent casualties and fatalities, because there are no reliable or verifiable source figures available."
Are all the casualties British?
No. The tables include details of overseas nationals who were killed in Afghanistan while serving with the UK Armed Forces.
Among the fatalities are nationals of Fiji, the Irish Republic, Jamaica, Nepal, New Zealand, South Africa and Zimbabwe.
Why do some of the numbers in the figures page appear different from MoD figures?
The MoD classification of "killed in action" covers a number of different types of incident including friendly fire and some accidental deaths.
In order to show a greater level of detail, we have split the data a different way and grouped them according to deaths caused by hostile action, accidents or other reasons. Therefore the number of fatalities caused by hostile action on our table will be smaller than the MoD's "killed in action" category.
The hostile category includes deaths caused by: improvised explosive devices (IEDs), roadside bombs or landmines; gunshot wounds; indirect fire, such as mortar or rocket attacks; hand or rocket-propelled grenades; suicide bombers; other causes.
