1. The use of administrative data in the turnover statistics for the service sector in Sweden

2. The Swedish survey on turnover in the service sector
Main users: National Accounts and Eurostat
One variable collected: monthly turnover
Estimates are produced monthly and quarterly
The produced estimates are turnover changes over time for a number of domains (subsets of the population)

3. Survey on Retail Trade
A sample survey based on information collected directly from the enterprises
Retail Trade is an important indicator of the economy
Due to timeliness, administrative data has not been possible to use instead of collecting data
Administrative data (VAT) is used as auxiliary information in the stratification and in the estimation phase to obtain an effective sampling design

4. Survey on Other Services – until year 2008
A quarterly census based on a mixture of:
administrative data (VAT) from the Swedish Tax Agency – used for all small enterprises
data collected from questionnaires – used for all large enterprises
A few NACE activities were based only on questionnaires

5. Survey on Other Services – until year 2008
Due to timeliness the third month in a specific quarter often was missing in the VAT-data
To produce the quarterly estimates using VAT- data values for the third month had to be imputed for the majority of the small enterprises
Current Ratio Imputation

6. Current Ratio imputation
The current ratio imputation works as follows:
The imputed turnover value for enterprise k month three:
enterprise k:s turnover value month one
enterprise k:s turnover value month two
enterprise k:s turnover value month three

7. Survey on Other Services – until year 2008
Current Ratio imputation worked very well in this survey, a conclusion based on evaluations, possible to do, in retrospect
The quality of the survey improved when introducing the census, in terms of:
Sampling error
Non-response
Strong focus on response burden at Statistics Sweden and the use of administrative data reduces the response burden among the small enterprises

8. Survey on Other Services – reference year 2008
The Swedish Parliament approved a change in return period from month to quarter, in force from first January 2008, regarding small enterprises.
Enterprises with an estimated annual turnover:
exceeding 40 million SEK are, as before, required to report VAT on a monthly basis
below or equal to 40 million SEK are required to report VAT on a quarterly basis

9. Survey on Other Services – reference year 2008
The VAT-return for a small enterprise must be submitted at the latest about 40 days after the end of the reference quarter
Due to timeliness VAT-data for small enterprises is complicated to use in the survey on Other Services
This approval of change in return period for small enterprises meant that Statistics Sweden was forced to collect the information direct from the enterprises and consequently use a sample survey again

10. Survey on Other Services – reference year 2008
The contribution from the service sector continues to grow which means that the entire sector now is an important indicator.
The new sample survey on Other Services is designed to produce preliminary results on a monthly basis and to produce definitive results on a quarterly basis
VAT-data is used as auxiliary information in the stratification and in the estimation phase to obtain an effective sampling design

11. Survey on the services sector, Retail Trade and Other services - future
Statistics Sweden approach is to:
use a sample survey (and collect information direct from the enterprises) for the monthly indicator
explore the possibility to use VAT-data for small enterprises in the production of the detailed quarterly estimates
Study different methods to use observed values in the VAT-data to compensate for, due to timeliness, enterprises not submitted the VAT return

12. Proportion observed turnover in the frame population for the turnover statistics - questionnaire for large enterprises and VAT-data for small enterprises
