What group of people have highest suicide rate in the US?

Answer 1

If you mean in terms of occupations, probably members of the armed forces, police officers, and perhaps truck drivers. Truck driving is a field where a number of military vets get involved because war made them more isolated from others. Driving a truck is mostly a solitary job, and it allows someone to feel in control while they are on the road.

Of course, living situations and disabilities are also a factor. Those estranged from their families are more likely to consider suicide than those in loving relationships. LGBT persons are more likely to commit suicide than heterosexuals. Divorced people are more likely to commit suicide than single people and happily married couples. Those who become disabled later in life may be more likely to commit suicide than either those disabled very early in life (excluding certain mental conditions) and those who suffer no disabilities.

IQ can be a factor to a point. Those who are right below the normal range are probably more likely to commit suicide than those in the normal range and those who are profoundly mentally challenged. Things are perhaps the hardest on those who have cognitive disabilities and are fully aware they have them.
