                     while the error is the amount of the difference between the actual and
                     estimated  value.  In  sample  surveys,  sample  error  can  be  measured
                     statistically and controlled through the adoption of probability sampling
                     methods.  Non‐sample  error  can  be  minimized  by  following  optimal
                     procedures throughout the various stages of survey implementation.
                     For administrative data, it may be difficult to optimize the organizational
                     and  technical  procedures  for  constructing  the  databases  in  order  to
                     minimize qualitative measurement error because these procedures are
                     controlled  by  the  data‐producing  agency  rather  than  the  statistical
                     agency. Thus, it may be difficult to  accurately evaluate the quality of
                     indicators sourced from administrative data.
                     Consistency    of    methodologies,     statistical   concepts   and
                     classifications:  Official  statistics  agencies  depend  on  the  concepts,
                     definitions, manuals, and statistical classifications recommended by the
                     international statistical organizations for many categories of economic,
                     social and demographic data. Using the administrative data as a source
                     for official statistics requires consistent concepts, definitions, manuals,
                     classifications,  and  appropriate  methodologies  to  achieve  integration
                     between  data  from  statistical  surveys  and  administrative  data,  which
                     maximize the benefit from the entire database in optimum way.
                     Timeliness: Lack of timeliness in the delivery of the data to the national
                     statistical  agencies  is  a  very  common  problem.  Some  delays  are
                     inevitable whereas others are because of inefficiencies in processes, lack
                     of priority given to statistical needs or insufficient resources.
                     The  large  size  of  administrative  files  can  mean  significant  processing
                     costs with a subsequent impact on timeliness.
                     Comparability: Administrative statistics should be consistent internally,
                     over time and comparable between region and geographic areas. On
                     other hand it should allow to combine and make joint use of related data
                     from different sources.
                     Interpretability:  The  interpretability  of  statistical  data  reflects  the
                     availability of supplementary information and metadata. The provision
                     of  metadata  is  essential  to  enable  public  evaluation  of  the
                     appropriateness of  the data for various uses. Metadata  also  provides
                     explanations  of  the  procedures  and  methods  of  treatment  that  have
                     been implemented in the construction of the data. A major challenge for
                     statistical  agencies  that  use  administrative  data  as  their  source  for
                     statistical indicators is ensuring the adequacy of metadata about the
                     administrative databases.
