  1. 2011 Key challenges • Peter Benton • Head of 2011 Census Design Authority

  2. Overview – key challenges • Address register • Address register • Address register • Integrated enumeration strategy • Increasing response in the hardest areas / groups • Mobility / migration • Quality Assurance • Internet

  3. Address Register Development • Revised approach • Stakeholder engagement and buy-in • Matching address products • Maximising match rates • Minimising duplicate addresses • LA involvement • Very positive step forward • Need to maximise commitment of resources • Need to minimise addresses to check • Need a simple process

  4. Integrated enumeration strategy (1) • Aims • Maximise response • Minimise variability • Minimise missed people in households • Simplicity for field staff and public • Publicity • Main messages • Targeting key groups / areas • Focus groups • ‘Boutique’ PR agencies • Address checking • Where to check? • Where to use full v visual check?

  5. Integrated enumeration strategy (2) • Delivery • Where to hand deliver? • All communals • Where address uncertainty remains • Where there are large households • All depends on approach to, and success of, address register development and checking • What instructions to give public when mis-delivered

  6. Integrated enumeration strategy (3) • Follow-up • Where to target resources initially • Being aware of mis-delivered questionnaires • Simple process needed for prioritising areas for follow-up and moving staff • But complex aim of minimising variability within hard-to-count strata within LAs • Maintaining linkage of questionnaire to address id

  7. Increasing response in hardest groups / areas • Priorities • Hardest 5% of LAs • Key population subgroups • Dealing with apathy / distrust • Depends on field and publicity • initial targeting of follow-up resources • good management information • flexible, simple field management processes • Good understanding of barriers / hooks and targeting of publicity messages

  8. Mobility / migration • Who to include? • Short term migrants • Usual residents overseas • Lost of challenges! Further research planned • Where to count people? • People will tell us what they want to tell us • Questionnaire instructions / question wording • More complex coverage assessment methodology • Overcount: Need to check for duplicates / wrong locations • Mass matching • Potential to use second residence info to focus search • Undercount: • As in 2001, plus • Some use of visitor info • Potential use of address register

  9. Quality Assurance • Plethora of alternative sources • Both a benefit and a challenge • Need to understand definitional differences • For Quality Assurance • For explanation of differences • Especially short term migrants and second residences • Need for contingency approach • What extra work will we do when we are not sure about the results for an area • How do we make best use of external expertise

  10. Internet completion Internet completion • Steep learning curve! • Managing peak response volumes • 25% by internet • Of those, 40% on census day • Of those, 40% 7-9 pm • 1 million HHs in 2 hrs? • Understanding bimodal differences and impacts • More duplicate responses
