Arya Samaj’s presence may be described as geographically wide yet numerically modest, with its deepest roots in particular regions rather than an even spread. Within India, its influence is especially visible in the northern and western belt, including Punjab, Haryana, Delhi, Uttar Pradesh, Rajasthan, Gujarat, Maharashtra, and parts of western Uttar Pradesh. In these areas, Arya Samaj is known less for large congregational temples and more for a network of institutions: DAV (Dayanand Anglo Vedic) schools and colleges, gurukuls, Sanskrit schools, orphanages, and social-service centers. Many local Arya Samaj mandirs or sabhas function as hubs for Vedic-style, non-idolatrous weddings, rites of passage, scriptural study, and reform-oriented activities. Its impact in South and East India is comparatively limited, which reinforces the sense of a movement that is significant yet regionally concentrated within the broader Hindu landscape.

Outside India, Arya Samaj has followed the pathways of Indian migration and indentured labor, becoming one of the earlier organized Hindu presences in several diaspora settings. It maintains sabhas and institutions in neighboring South Asian countries such as Pakistan, Bangladesh, Nepal, and Sri Lanka, though often on a small or low-profile scale, especially where Hindu communities themselves are under demographic or social pressure. Across the Indian Ocean and parts of Africa—Mauritius, Fiji, South Africa, Kenya, and Tanzania—its imprint is evident in temples, schools, and social-service activities among people of Indian origin. In the Western world, centers exist in the United Kingdom, the United States, Canada, and also in continental Europe, Australia, New Zealand, and Caribbean countries like Guyana, Suriname, and Trinidad and Tobago, typically serving diaspora Hindus drawn to Vedic worship without idols and to community education.

Viewed as a whole, Arya Samaj stands as a movement whose institutional and intellectual legacy often exceeds the visible size of its self-identified membership. Its presence is dense and historically influential in parts of North and West India, while remaining a smaller, though steady, current within many overseas Hindu communities. The pattern that emerges is not of a mass devotional movement, but of a reformist stream that has quietly shaped education, social upliftment, and understandings of Vedic practice wherever it has taken root.
