DLI Western Training - ACCOLEDS 18

Part 2: 2011 NHS Dissemination

 Release strategy and changes to product line compared to census

  • Tight timeframe between releases with many topics per release – operational

challenges

  • No formal ‘data visualization’ products (i.e., Visual NHS, Data Navigator, Pyramids)
  • No Highlight tables and fewer number of data tables and thematic maps
  • Reduced levels of geography … data tables down to CMA/CA on day of release, NHS

profile down to CD/CSD and CTs (began with second NHS release) – more in ‘cluster’ to satisfy identified data gaps

  • NHS User Guide made available with first NHS release – key information includes:
  • Survey content and target population, voluntary nature;
  • Sampling design and collection – non-response bias /follow-up, response rates;
  • Data processing – edit and imputation, weighting;
  • Data quality assessment and indicators – sampling/non-sampling error, comparability;
  • Data dissemination for NHS standard products – data suppression: confidentiality and/or

quality, coverage;

  • Appendices: NHS questions, reference guides, comparing 2011 Census pop. counts and NHS
  • pop. estimates by size of CSDs.
  • List of areas suppressed – now include ‘reason why’ … DQ and/or confidentiality

Part 2: 2011 NHS Dissemination

 Data quality … Global non-response (GNR) and coefficients of variation (CVs) Global non-response rate (GNR):

  • For NHS estimates, the GNR was used as an indicator of data quality
  • Combines complete non-response (hhld) and partial non-response (question) into single rate
  • Value of the GNR is presented to users in all NHS standard data products
  • Smaller GNR indicates a lower risk of non-response bias and as a result, lower risk of inaccuracy
  • NHS threshold for estimates' suppression is GNR 50% or more (census, 25% or more)
  • Suppression based on both confidentiality rule (i.e., pop. estimate greater than 40) or GNR

Coefficient of variation (CV):

  • Measure used to describe the precision of an estimate. The smaller the CV is, the more precise the
  • estimate. CV of an estimate is the ratio of the standard error of the estimate and the estimate itself,

expressed as a percentage. CV is indicator in survey environments.

  • NHS CVs available for selected variables for Canada, provinces and territories
  • Note available for a comparison of CVs for a variety of conceptually comparable variable estimates at

various levels of geography for the 2011 NHS and the 2006 Census long form
