Objectives

The quality datasheet seeks to establish a list of quantitative indicators that reflects the quality of a specific statistics operation for each of the quality dimensions or factors established by EUROSTAT. This quality datasheet has been prepared based on the standard quality indicators recommended by the European authority and on others based on the procedures of the EUSTAT statistics operations.

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 produced 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 “Website Demand Report” prepared by EUSTAT: It includes all the hits for the data, information, documentation, etc. related to a specific statistics 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 reflects the number of times that the specific statistical operation has been mentioned in any of the media (press, digital media, radio and television). The value of this indicator for all the statistical operations is included as the reference value.

• Accuracy and reliability indicators
  • Total response rate (%) - Annual Average
    The real value is the average of the monthly response rates. The monthly 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 (situational)
    The real value of this indicator will be given by the number of periods where the established economic cycle timeline has been fulfilled. The reference value is the total number of annual reference periods, in this case 4 as it is quarterly data.
  • Average annual time-lag (days)
    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. The time-lag that is established in the objectives of the statistics operation in the Annual Statistics Programme is included as the reference value.

• Indicators of comparability over time
  • Length of comparable time series (Years)
    The real value of this indicator shows the number of annual periods where the time series without “jumps” has been maintained. The "10 years or more” value, the category suggested by EUROSTAT for this type of indicator, is the reference value.

• Accessibility and Clarity indicators
  • Number of methodological documents disseminated on the website. (“Methodology & Quality” section)
    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.
  • Number of publications disseminated (different formats)
    The real value of this indicator contains the number of different formats in which the information is published about the statistics operations: Economic Cycle Graphs, Statistical Tables on the Website, Tables in the Databanks, Quarterly Newsletter, Press Release, Main Indicators.
  • Minimum number of “clicks” needed to access the data tables of the operation
    The real value shows the minimum number of “clicks” needed to access the data tables of the operation.

• 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.
