Challenges in the implementation of SIMSTAT

Introduction

Nordic meeting

16 September 2014

Jennie Bergman

Introduction

• Sweden is not part of ESSnet and the pilot study

• Presenting SIMSTAT to the Advisory Scientific Board of Statistics Sweden in October 2014• Professors from universities and representatives

from other statistical institutes • Discussion and recommendations on future work• Main focus on methodological questions

What will happen if SIMSTAT is implemented? • Mandatory exchange of micro-data for dispatches• One/two new variables for dispatch

• partner id and/or country of origin

• Optional collection of arrivals (coverage rate not regulated in EU legislation)

• Member states decide themselves how to use the exchanged micro-data • Not at all• Only for quality checks and asymmetry studies• Mixed mode: use the exchanged data to some extent

and still collect some arrival data• Use the exchanged data and no collection of arrivals

What will happen in Sweden?

• The burden for the Swedish dispatch PSIs will increase • Only collects mandatory variables today

• Short term: Will not be able to use the exchanged micro-data due to resource constraints

• Medium term: Use the exchanged data for asymmetry studies and quality checks

• Long term: Have to reduce the burden -> lower the coverage rate for arrivals so less enterprises have to report and use the exchanged data

Opportunities and challenges

• Response burden • Data quality

• Time-series • Asymmetries

• Confidentiality and trust of PSIs• Changes in publishing

• Work process• Publishing date

• Data handling and administrative problems• Collaboration and interdependence between NSIs• Control over the data

Questions for discussion

• Which are the main challenges and how should we deal with them?

• Which are the most important questions to discuss with Eurostat?

• Do you see any problems with adding ‘country of origin’ on dispatch?

• If using a mixed-mode approach, how will you handle it?

• Results of the quality evaluation (DK)?
