EQLS 2012 - Coding
The EQLS does not include open-ended questions; therefore there was no need for coding this type of question. However, recoding schemes were applied to produce internationally comparable information regarding educational attainment and income. Information about respondents’ educational attainment was recoded into categories of the International Standard Classification of Education (ISCED), while income information that referred to the national currency in each country was recoded to euros based on the exchange rates on 16 May 2011.
Finally, the answer categories for the question on occupation can be matched with the 1 digit ISCO categories that were used in the 5th European Working Conditions Survey which enables comparison between the two surveys for this variable.
A coding report is available.
