The label committee ensures that the survey does not place an excessive burden on respondents.

In addition, other decisions were made to limit the burden on respondents:

• the EACEI 2016 sample is the same as this of 2015, because of the EACEI 2015 extension ;

• the part of the EACEI 2016 sample is negatively coordinated with the thematics enterprises surveys ;

• collection is done electronically ;

• the sample of the extension collected at the end of the year (second wave) was not intended to be interviewed by a panel and was therefore drawn independently of the numbers of the previous surveys.
