The ESS User Statistics documents the usage of ESS data from the launch of ESS Round 1 in 2002 and to date. Two groups of users are reported:
- Registered users: registered on the ESS website and thereby eligible for using ESS data
- ESS data downloaders: registered users who have actually downloaded ESS data at least once
The User Statistics includes tables showing numbers of registered users and ESS data downloaders by country, user type (faculty members, students etc.) and data type (ESS round, cumulative data and multilevel data).
