The study was aimed at finding out the age and gender difference in religiosity among the youth and the elderly. Four aspects of religiosity were studied. They were Daily Spiritual Experience, Values and Beliefs, Forgiveness and Private Religious Practices. The sample consisted of 100 elderly (50 males and 50 females) and 100 youth (50 males and 50 females) living in Delhi, the capital city of India. The age group of the elderly sample was 60 -75 years. The age group of the youth ranged from 20-30 years. It was seen that the elderly were significantly higher than the youth on Daily Spiritual Experience, Values and Beliefs and Private Religious Practices. On Forgiveness the elderly were higher but the difference was not significant. No gender difference was found on any of the domains of religiosity. Implications of religiosity on health and wellbeing are discussed.
