Objectives

The quality datasheet seeks to establish a list of quantitative indicators that reflect the quality of a specific statistical operation , for each of the quality dimensions or factors established by EUROSTAT. This quality datasheet has been prepared using the standard quality indicators recommended by the European authority and on others arising from EUSTAT’s own statistical operations procedure. This quality datasheet has been prepared using the standard quality indicators recommended by the European authority and others arising from EUSTAT’s own statistical operations procedure.

Whenever possible, a reference value whose mission is to facilitate the interpretation of the “goodness” of the given indicator will be added alongside the real value of each indicator. And in general, it shall be expressed by a minimum or maximum reference value of the indicator.

Indicator Descriptions

• Relevance Indicators
  • Satisfaction index and importance level by operations groups
    The real value of this indicator is calculated using the results of the last available User Satisfaction Survey prepared by EUSTAT. The value range, the minimum and maximum of these indicators (between 0 and 5), is included as the reference value.
    User satistaction survey
  • Number of website hits
    The real value of this indicator is calculated using the annual figures from the Report on Website Demand produced by EUSTAT. It includes all the hits for the data, information, documentation, etc. related to a specific statistical operation . All web hits for the statistical operations for the relevant annual period are included as the reference value.
  • Number of media hits
    The real value of this indicator is calculated using the annual figures from the Dissemination Report produced by EUSTAT. It is the number of times that EUSTAT was referred to in any of the media with regard to a specific statistical operation . The total number of articles referring to Eustat in the media, irrespective of the statistical operation , is included as the reference value.

• Accuracy and reliability indicators
  • Total response rate (%) - Annual Average
    The real value of this indicator is the average of the quarterly response rates. The quarterly response rate is calculated as the quotient between the number of surveys conducted during the benchmark period out of the total units eligible to be surveyed.

• Opportunity and punctuality indicators
  • Schedule compliance
    The real value of this indicator will be given by the number of periods where the established economic cycle timeline has been fulfilled. The total number of annual reference periods is included as the reference value.
  • Average annual time-lag
    It is the time between the reference period of the data and their availability. The real value entered is an average value of the time-lags recorded throughout all the periods of the year. If the operation is structural, the annual time-lag will be considered. The time-lag that is established in the objectives of the statistical operation in the Annual Statistics Programme is included as the reference value.

• Indicators of comparability over time
  • Length of comparable time series
    The real value reflects the number of periods registered in the data series that are free of “gaps” either caused by the specific features of a certain period or by substantial methodological changes The greater the indicator, the more comparable the series is considered to be over time. The "10 years or more” value, the category suggested by EUROSTAT for this type of indicator, is recommended as the reference value.

• Accessibility and Clarity Indicators
  • Number of methodological documents disseminated on the website
    The real value of this indicator reflects the total number of documents (reports, datasheets, tables,…) available in the “Methodology and Quality" section of the website, for each statistical operation .
  • Number of publications disseminated
    The real value of this indicator contains the number of different formats in which the information on the statistical operation is published. These formats are described in the Technical Project of the statistical operation .
  • Minimum number of “clicks” needed to access the data tables of the operation
    The real value of this indicator contains the number of clicks required to reach the statistics tables publishes on the Eustat website.

• Other Indicators
  • Monetary cost
    The real value reflects the transition cost of the operation and it uses the EUSTAT total transition costs as the reference value.
