भारत की 1.028 अरब जनसंख्या में 4,200,000 लोग जैन धर्म के अनुयायी हैं, यद्यपि जैन धर्म का प्रसार बहुत दूर तक है जो जनसंख्या से कहीं अधिक है। भारत के केन्द्र शासित प्रदेशों एवं सभी राज्यों में से ३५ में से ३४ में जैन लोग हैं, केवल लक्षद्वीप एक मात्र केन्द्र शासित प्रदेश है जिसमें जैन धर्म नहीं है। झारखण्ड जैसे छोटे राज्य में भी 16,301 जैन धर्मावलम्बी हैं और वहाँ पर शिखरजी का पवित्र तीर्थस्थल है।

It is without beginning and it will never cease to exist. The darkness of error enveloping the truth in certain, periodically occurring aeons clears up again and again so that the brightness of the Jaina-faith can sparkle again anew."

Samaṇ Suttaṁ. नई दिल्ली: Bhagwan Mahavir memorial Samiti. “The Historians have so far fully recognized the truth that Tirthankara Mahavira was not the founder of the religion. He was preceded by many tirthankaras. He merely reiterated and rejuvenated that religion. It is correct that history has not been able to trace the origin of the Jaina religion; but historical evidence now available and the result of dispassionate researches in literature have established that Jainism is undoubtedly an ancient religion.” Pp. xii – xiii of introduction by Justice T.K.Tutkol and Dr. K.K. Dixit.

"Thus not only nothing, from the philosophical and the historical point of view, comes in the way of the supposition that Jainism was established by Parsva around 800 BC, but it is rather confirmed in everything that we know of the spiritual life of that period."
