National Statistics Quality Review of UK Maritime Statistics International Maritime Statistics Forum 16 April 2007 Jeremy Grove, UK DfT
Overview • What are we reviewing? • Why & how are we reviewing it? • Progress: emerging findings
What are we reviewing? • Maritime Freight and Sea Passenger Statistics collected under EU Directive 96/64/EC • Current system since 2000 - The Statistical Returns (Carriage of Goods and Passengers by Sea) Regulations 1997 (Statutory Instrument No. 2330) • Previously collected annual statistics from ports
Freight data (MSD system)… • Major ports (>1 Mt) • Route/cargo detail – lines/agents (MSD1) • Port totals – ports (MSD2, MSD2X) • Minor ports • Total tonnage in/out (MSD5)
……freight data…… • Initial chasing & validation by collection agent (BMT Reliability plc) • Oracle data repository and Access database • Data submission methods
….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
Sea passengers • 30+ ferry operators • 20+ cruise lines • 1 page monthly return • Easy!
Publications and outputs • Maritime Statistics (Oct) • Provisional (May) • Sea Passenger bulletin (March) • Transport Statistics Great Britain (Sept) • Focus on Ports (2006) • Eurostat • DfT Web Site
Why & how are we reviewing it? • Working well, but 6 years on • National Statistics Quality Review Programme • Survey Control Procedures } do both
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”
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
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
Key Aims of Review • User needs & data quality • User survey – meetings & seminars • Data providers’ needs • Data provider survey • Process review • Internal & external review • Links with other data sets • Visits - interviews
Progress to Date -Emerging Findings • User Survey • Data provider survey • Process review • Other data sets
User Survey • 74 sent + PB + web site • > 40 returned (43%) J • Access: + pdf, + spreadsheet, (- paper) • Popular data: + containers, + major ports, (- fleets) • Many uses for data • Popularity of data - fulfilling need • Qualitative results – still to come
…user survey - Gaps • Origin & destination – onward mode • Transhipment • Seasonal data • Timely data
Data Provider Survey • 181 sent out • 105+ returned (58%) JJ • Compliance burden (c. £400k?) • Still to come: • Web-based form • Problem areas • Ideas for improvement • Helpline / web site feedback • Use of data
Process reviews • So far largely confined to details • Reducing resource requirement (IT) • Improving data quality (checks) • Quarterly grossing • Enhance security & data provider feedback • Clearer delineation of contractor/DfT work
Other data sources… • Trade Statistics (HM Revenue & Customs) • Mainly value based • Wide data set, but reducing • Intra-EU data very limited • Limited data overlap • Maritime & Coastguard Agency • Data collection to increase • No overlap • Very limited scope for cross-checking
…other data sources • Port Community Systems • Help with some data gaps? • DfT ro-ro survey • ‘Merge’ data collection - done • More comparison of results • Other ideas • Container tracking? • Industry sources on sea passengers • Trade sources
What Next? • April-May – complete analysis & draft report • June – Project Board considers report • Submitted to Ministers & National Statistician • Published on ONS web site • Carry out Action Plan
