Sweden

Background
• ”The shoe problem” 2008 lead to requirement for
new process
• Guidelines produced in 2009
• Clarified organisation within Statistics Sweden
• Communication Department – coordinate handling
• Process Department - receives reports of errors and
analyses reasons
• Our experiences, reactions from users, other
statistical offices,...
• Need to adjust guidelines for handling of errors
Principles
• Openness about errors and corrections
• Errors should be corrected as quickly as possible
• Handling varies depending on the type of product
and how serious the error is
• The user's perspective is the determining factor for
assessing the seriousness of the error
• Corrections should be visible and give relevant
information
Proposal for handling of errors
• Major (significant) errors in our most important products
(CPI, LFS, GDP)
•
•
•
•
Notify that an error has occurred
Remove the incorrect information
Decision to publish on a certain day at 09:30
Inform important users separately (but at the same time as
information about the error is published !)
• Inform internally
• Minor errors in our most important products
• Publish at 09:30 but without notification in advance
• Other products
• Notify about major errors locally on the website
• Make corrections as soon as possible
(product page)
Issues
• Speed versus simultaneity
• Simultaneity is important in standard publishing of
statistics and therefore an issue in corrections
• Simultaneity is crucial for stock market affecting stat
• Removing the incorrect information quickly
versus creating uncertainty among users
• We have tried ”remove everything” but now more
restricted
• Informing about ”everything” versus adapting to
the needs of users
• Push for most important errors, pull for the rest
