This article is among the first to explore this approach, using a random sampled web survey (N=3,224) with a three-level search tree with 1,603 occupations and offering a text box at the bottom of each 3rd level list. 67% of respondents ticked in total 585 occupations, of which 349 by at least two respondents and 236 by only one, pointing to a long tail in the distribution. The text box was used by 32% of respondents, adding 207 occupational titles. Multivariate analysis shows that text box use was related to poor search paths and absent occupations. Search paths for five of the 23 first-level entries should be improved and the look-up table should be extended to 3,000 occupations. In this way, text box use and thus expensive manual coding could be reduced substantially. For such large look-up tables semantic matching tools are preferred over search trees to ease respondent’s self-identification and thus self-coding.\u003C\u002Fp>","light",{"text":40,"link":41},"Contact us",{"title":40,"url":42,"description":40,"rel":43,"type":44,"id":45},"\u002Fabout\u002Fcontact","follow","internal",24590,[],[],[],[],false,"\u002Fwork\u002Fliving-wages\u002Fcontact-us","\u003Cp>Welcome to WageIndicator.
