What is the definition of agoraphobia?
A phobia is usually defined as the severe, unrelenting fear of a situation, activity, or thing that makes one to want to avoid it. The definition of agoraphobia is the severe anxiety about being outside or otherwise being in a situation from which one either cannot escape or from which escaping would be difficult or embarrassing.
Phobias are often underreported and underdiagnosed, likely because many phobia sufferers find ways to avoid the situations to which they are phobic. The fact that agoraphobia often co-occurs with panic disorder makes it even more difficult to determine how often it occurs. Other statistics about agoraphobia include that researchers estimate it occurs from less than 1% to nearly 7% of the population. The age of onset for this condition is most often during the mid to late 20s.
