countries, such information does either not exist at all in the required form (i.e. establishments stratified by size-classes) or it is not made public. The major challenges for the sampling and weighting of the “mixed” public/private sectors “Education” and “Human Health and Social Work Activities” are somewhat different: Organisations of these sectors of activity are normally not totally excluded from address sources, but are in several countries clearly underrepresented. Where this is the case, the available addresses mostly cover the private units within these sectors (i.e. private schools, hospitals etc.), but not the public ones (public schools, public hospitals etc.). This underrepresentation is often also reflected in the sources of statistical information which in several countries do not fully cover the units in these sectors. Mostly, they map the private units only. But not the public ones. 19
2. The address registers 2.1. Types of address-registers In a preliminary study for the first establishment survey of the European Foundation for the Improvement of Living and Working Conditions (ESWT 2004), Hermann Groß stated that “(…) it is recommendable to take the most recent and most comprehensive directory of all establishments with 1 or more employees in the countries under investigation" (Groß 2003, p. 13). This at the first glance simple and obvious demand is not as easy to fulfil as it might seem. In most countries there is absolutely no choice between different registers of establishments and in several countries there is no establishment register available at all. Nevertheless, topicality and comprehensiveness are important criteria of judging the quality of an address source. Topicality Topicality was not a real problem with any of the registers used for the ESENER with certain limitations regarding the registers used for Turkey. Most of the registers used for the ESENER 2009 claim to be updated at least once a year, many even quarterly or weekly. Experiences have however shown that the scope and quality of the updates varies widely: While some registers are up-dated by regularly contacting all listed establishments - e.g. via telephone interviews or via mail-questionnaires – in other cases up-dates are made for those units only which report changes on their own initiative. In some registers claiming to be updated on a regular basis, firms which are dissolved or go bankrupt are not de-registered at all. Also, significant increases or decreases of the workforce are often not reported to the institution responsible for maintaining the address-register. The share of quality neutral non responses (e.g. establishments where the indicated telephone number was wrong or inactive) and the deviations between the number of employees as indicated in the address source and the number of employees according to the survey results are important measures for judging on the topicality of an address source. Comprehensiveness of sector coverage With regard to comprehensiveness, a judgement of the different sources is quite difficult. The total number of entries e.g. is only a very weak indicator for the completeness of an addressregister as long as the register does not embark all establishments in the country. If the latter is not the case, entries might be concentrated on specific types of establishments. For example there might be a good coverage of large establishments, but an only poor coverage of the smaller ones (or vice versa). Or registers might be complete for certain sectors of activity but include only very few addresses of others. Other possible criteria for inclusion or exclusion of establishments can be their legal status, their geographical location within the country, the amount of turnover, the fact whether they are paying taxes to the national tax office or whether or not they are enrolled in the trade-register. It is not essential for a survey of this kind that an address-register has a complete listing of all existing addresses of establishments (with 10 or more employees) – although this of course 20
