The IDN World Report research team has been studying internationalised domain names since 2011, and has a data set for IDNs stretching back to 2009 – when IDNs first became available at the top level.

From 2011-2015, the World Report was published as a printed and then PDF version. Beginning in 2016, the IDN World Report has moved to a fully online presentation.  Archived reports are available by following the links below.
