In many legal jurisdictions, the manner of death is a determination, typically made by the coroner, medical examiner, police, or similar officials, and recorded as a vital statistic.
International Classification of Disease codes are sometimes used to record manner and cause of death in a systematic way that makes it easy to compile statistics and feasible to compare events across jurisdictions.
In humans, a few examples include slower healing of skin tissue, thickening of blood vessel walls, and a less effective immune system.
Still, many doctors will refer to a cause of death as "old age" if it is more comforting for loved ones than providing specific details.
[11] For example, the discovery of a partial human skeleton indicates a death, but might not provide enough evidence to determine a cause.
For example: In the United Kingdom, when people die, either a doctor writes an acceptable natural cause of death medical certificate, or a coroner (procurator fiscal in Scotland) investigates the case.
[15] In the unified legal jurisdiction of England and Wales, most deaths are certified by doctors without autopsy or coroner involvement.
A death ruled as homicide or unlawful killing is typically referred to police or prosecutor or equivalent official for investigation and criminal charges if warranted.
