  5. ……freight data…… • Initial chasing & validation by collection agent (BMT Reliability plc) • Oracle data repository and Access database • Data submission methods

  6. ….still freight data (yawn) • BMT send data weekly to DfT • Further quality and credibility checks at DfT • Aggregation of route and port data • Eurostat ‘mirror’ checks

  7. Sea passengers • 30+ ferry operators • 20+ cruise lines • 1 page monthly return • Easy!

  10. UK National Statistics Quality Review Programme (2000) • Key National Statistics subject to regular quality review: • meet user needs (consult) • meet quality standards • review methods (vs. other countries?) • identify areas for improvement • publish review & action plan, approved by “National Statistician”

  11. Survey Control procedures (1969) • All government surveys of businesses and local authorities to be reviewed every 5 years: • ensure necessary and appropriate • estimate survey compliance burden • ensure burden minimised • promote best practice in data collection

  12. Management of review • Published in Project Initiation Document (PID) www.dft.gov.uk/pgr/statistics/standardsreview/450ongoingreviews • Management • Project Board – users & data providers (JD, DG…) • Review Team • Report to National Statistician & Ministers
