Risk as a Proxy for Need Risk Factors : Risk factor is defined as any ascertainable In every society there are communities, families and individuals characteristic or circumstance of a person or group of persons whose chances of future illness, accident and untimely death that is known to be associated with an abnormal risk of are greater than others; they are said to be vulnerable owing to developing or being especially adversely affected by a morbid peculiar set of characteristics they share.
