I'm struggling to find some data as to the (estimated) number of installations/user base/market share of Hibernate and/or EclipseLink.

This information would help in interpreting numbers like '# of bug reports opened' or '# of S/O questions' per product, but it seems that's not as readily available as I would expect.

Can anyone point me to some resources in this regard?

    How would you judge market share that isn't subjective or opinionated? Market share questions generally get closed on stack overflow for these reasons. – Chris Oct 31 '14 at 15:46

    and indeed, what use does it have, other than allowing people to follow like sheep of course, rather than doing a real assessment based on capabilities – Neil Stockton Oct 31 '14 at 17:46
  • @Chris What do you mean? If there are meaningful figures about the relative use of programming languages, why shouldn't there be some about JPA providers? – JimmyB Oct 31 '14 at 20:14
  • @NeilStockton You can trust me that I know how to interpret the numbers right. And we all know that there's more to different technologies than the capabilities present at a given instant. – JimmyB Oct 31 '14 at 20:21

According to RebelLabs 2014 java tools and technologies report, Hibernate was having a 67.5% market share, meaning that all other providers combined share less than 1/3 of the whole market.

The 2014 Data Access frameworks market share is:

  • Hibernate : 67.5%
  • Plain JDBC : 22%
  • JDBC Template : 19.5%
  • EclipseLink : 13%
  • MyBatis : 6.5%
  • JOOQ : 1.5%
  • Other : 7%

In a 2016 survey, the following results have been obtained:

  • Hibernate : 72%
  • EclipseLink : 13%
  • OpenJPA : 2%
