The LFS d<strong>at</strong>a were however not used 1:1 as basis <strong>for</strong> the estim<strong>at</strong>es. An analysis of the<br />
available d<strong>at</strong>a (e.g. comparison of LFS d<strong>at</strong>a on the distribution of employees with register<br />
based d<strong>at</strong>a on the distribution of employees shows th<strong>at</strong> the LFS generally tends to<br />
overestim<strong>at</strong>e the number of establishments to a certain degree. This holds especially <strong>for</strong> the<br />
smaller units with 10 to 19 <strong>and</strong> 20 to 49 employees. One of the reasons <strong>for</strong> this phenomenon<br />
is maybe the definition of establishment as “place where you worked” (see chapter 3.2) in the<br />
LFS questionnaire. Some respondents might have referred their answer to a smaller unit than<br />
the establishment in the sense defined <strong>for</strong> the survey. In consequence, in the estim<strong>at</strong>es made<br />
<strong>for</strong> the <strong>ESENER</strong> <strong>2009</strong>, we there<strong>for</strong>e slightly reduced the number of employees in these two<br />
size-classes. This brought the LFS figures more in line with available official st<strong>at</strong>istics on the<br />
distribution of employees on establishments.<br />
Estim<strong>at</strong>es made to improve weaknesses of the provided establishment level st<strong>at</strong>istics<br />
In countries where the required st<strong>at</strong>istics were available <strong>for</strong> establishments, but showed very<br />
clear weaknesses regarding any of the cells of the m<strong>at</strong>rix, the LFS d<strong>at</strong>a were also used <strong>for</strong> an<br />
improvement of the st<strong>at</strong>istical base <strong>for</strong> the sectors in which deficiencies were identified. This<br />
type of correction was mostly limited to countries with deficiencies in the sector “Public<br />
Services”.<br />
In all countries where reliable st<strong>at</strong>istics on the distribution of establishments over the various<br />
cells of the sampling m<strong>at</strong>rix were available, but no in<strong>for</strong>m<strong>at</strong>ion on the distribution of employees<br />
(e.g. the Netherl<strong>and</strong>s), estim<strong>at</strong>es <strong>for</strong> the employee proportional st<strong>at</strong>istics were calcul<strong>at</strong>ed on<br />
base of the official d<strong>at</strong>a <strong>for</strong> the distribution of establishments <strong>and</strong> not – as in the countries<br />
where establishment level st<strong>at</strong>istics were totally lacking - on base of the LFS.<br />
