Answer

Based on JAINA’s current center directory, there are about 63 Jain centers/societies listed in the USA, and 4 listed in California. JAINA also describes itself as an umbrella organization of 70 Jain Centers in North America. ( jaincenters.jaina.org)

Explanation

The California listings shown in the directory are:

• Jain Center of Greater Sacramento
• Jain Center of Northern California
• Jain Center of S. California
• Jain Society of San Diego. ( jaincenters.jaina.org)

This is a directory count, not a perfect national census, because many Jain places in the U.S. are listed as centers, societies, or shared temple communities rather than standalone temples. ( jaincenters.jaina.org)

Spiritual Understanding

In Jain Dharma, the true strength of a temple is not only in its number, but in the purity of bhav, regular darshan, swadhyaya, and seva.

Takeaway

If you want, I can also give you a state-wise list of Jain temples/centers in the USA, especially California.
