[1] In October 2005, the word ietsisme was included in the 14th edition of the Dutch Language Dictionary Dikke Van Dale.
[citation needed] More recently, the word ietsers ("somethingers") has emerged in the Netherlands to describe people of this viewpoint, but this has not yet been widely borrowed into English.
The term ietsism is becoming more widely used in Europe, as opposed to the phrase 'spiritual but not religious' which prevails in North America.
An opinion poll conducted by the Dutch daily newspaper Trouw in October 2004 indicated that some 40% of its readership felt broadly this way, and other Northern European countries would probably get similar rates.
From a December 2014 survey by the Vrije Universiteit Amsterdam, it was concluded that the Dutch population has 27% ietsists, 31% agnostics, 25% atheists and 17% theists.
