You asked

I writing to you to make this freedom of information request of "how many people have died in Bristol due to being Homeless".

We said

The mortality statistics we produce come from information collected at death registration. We code all conditions certified on the death certificate using the classification structure in the International Classification of Diseases (ICD) published by the World Health Organisation. From all of these conditions an underlying cause of death is selected using ICD coding rules. The underlying cause of death is defined as the disease or injury that initiated the train of morbid events directly leading to death. By definition, homelessness cannot be selected as a cause of death or used in mortality coding, so we are unable to provide you with statistics on those who have died due to being homeless.
