Possibilities of exploiting administrative data in short term statistics in Poland

Thestudyprocedure

  • Transforming administrative data sources into statistical data sets

  • General population (MEETS) consisting of companies in the DG-1 survey which were successfully matchedwithinformation from the the KEP, CIT, PIT and ZUS databases

  • Mean revenue was estimated using a calibration estimator with a known vector of the population total of auxiliary variables (the Horvitz-Thompson estimator was used as a benchmark).

Thestudyprocedure - cntd

  • Simulation: 5%, 10% and 15% samples were drawn from the MEETS dataset

  • After obtaining a sample, information about revenue (dependent variable Y) for some enterprises was replaced with missing data

  • Different approaches were used to generate missing data: random fashion (option 1), missing data were attributed to enterprises with the lowest (option 2) and highest (option 3)revenue

  • 500 iterationsperformed for each option, the expected value of revenue,the expected value of the bias

Conclusions

  • It’shard to obtainadministrativeregisters (system barrier)

  • The direct use of administrative data in short-term statistics is limited by the overly long time of data processing and a long period of waiting for data to be transferred by their administrators.

  • Administrative databases can be used as direct data sources for surveys, as a source of information to complete missing data, as a source of data for comparison with information collected in statistical surveys conducted by means of statistical reporting forms

  • The databases are a rich source of potential auxiliary variables, which can improve the quality of estimations by reducing the negative effect of non-response in statistical reporting.

Conclusions

  • The use of all available information about selected variables helps toreduce the respondent burden and improve the efficiency of estimators

  • Use of administrative data in producing business statistics may not completely solve all its problems (highly right-skewed distributions, very high differentiation and high concentration) but itcan significantly contribute to minimizing their negative effects.

  • Calibrationapproach can improve the quality of short-term estimation

  • Calibrationcombined with the methodology of small area statistics, can increase the range of estimation methods available in business surveys
