Canadian Community Health Survey (CCHS) - Annual Component Survey Overview - DLI Halifax Training May 9 th, 2019

Overview • • • Survey Overview Content overview through the years Important changes about 2015 redesign 2015 -16 CCHS PUMF 1 Future modernizations 1 – Public Use Microdata File

Survey overview - history • Started with Health Information Roadmap -1999 • Adoption of an indicator framework • • • Health behaviours Health surveillance Access to health care system • CCHS annual program and focus content program • Governing committee – Canadian Population Health Survey Program • Health Canada, Public Health Agency of Canada • Expert groups 3

Survey Overview - Objectives • Health surveillance at the national, provincial and sub-provincial levels • Analysis on small populations and rare characteristics • Readily available data to a diversified user community in a timely fashion • Flexible survey instrument 4

Survey Overview: Design • Residents of private households aged 12 and over • Exclusions: • Aboriginal reserves / settlements • institutions (health institutions, prisons, religious institutions, convents, etc. ) • members of Canadian Forces • Residents of certain very remote areas • Coverage (general) ~97% of targeted population • Designed to provide reliable estimates at the health region level with two years of data 5

Survey overview: Health Regions • Administration of health in the provinces is divided into health regions. • PEI and territories each are designated as their own single HR • For CCHS 2015 -2016, data was collected for 104 HRs in the provinces, in PEI and in each territory, totalling 108 HRs • This is the lowest level of geography on the PUMF, after some grouping* 6

Survey overview: Collection • The CCHS is collected by interviewers using a computer based questionnaire: • 20% in person, and • 80% by telephone • Respondents aged 12 -15 interviewed alone with parental consent • 2. 5% of cases completed by proxy 7

Survey overview: Data processing • During the interview, questions get skipped for various reasons and need coding: • Non-response • Interview incomplete • Question not relevant These cases are coded as “Not stated” Coded as “Not applicable” • “Other – specify” responses are sometimes recoded to a response category • Derived variables are added to the file based on responses 8

Survey overview: Weighting • Each respondent represents themselves and others in the population • The sample weight WTS_M indicates the population represented by each respondent • Weights have been adjusted for nonresponse and calibrated to match population estimates: HR*sex*age group 9

Survey overview - content • Three main types of content in survey • Core: all years, all respondents • Theme: certain years, all respondents • Optional: certain years, certain provinces/territories • Other content not available through DLI: • Buy-ins • Rapid responses • Sub-samples 10

CCHS Redesign of 2015 • Frame changes • Household survey frame for adults • CCB for youth 12 -17 • Collection methods • More telephone interviews overall (incl. for all youth respondents) • Sample allocation more responsive to change • Territorial coverage only over 2 -years 15

CCHS - PUMF details • Previous two year PUMFs: • • Cycle 1. 1 (2000/2001) Cycle 2. 1 (2002/2003) Cycle 3. 1 (2004/2005) 2007/2008 2009/2010 2011/2012 2013/2014 2015/2016 • Previous one year PUMFs: • 2010 • 2012 • 2014 16

Included core content for CCHS 2015 -2016 PUMF § Alcohol Use § Chronic Conditions § Contact with health professionals § Exposure to Secondhand Smoke § Flu Shots § Fruit and Vegetable Consumption § General Health § Height and Weight § Physical Activities for adults/youth § Primary Health Care Providers § Smoking § Maternal experiences § Administration § Age § Labour Force § Main occupation § Socio-demographics 17

Design for CCHS PUMF • 2015/16 PUMF contains 109, 659 records • 1, 199 variables • Geography variables • Province / territory of dwelling* • Health region of dwelling (grouped) • Canadian Active Living Environment (CANALE) 19

Canadian Active Living Environnent (CANALE) • New variable for CCHS PUMF • Provides additional geospatial value to the file • Scores (1 -5) each 2016 DA based on the active living environment (intersection/dwelling density, points of interest, and transit stops). • To link to CCHS, 2011 DAs from the file were linked with 2016 DAs in CANALE file. Multiple matches were dealt with random selection proportional to population size. • Included in pre-masking to prevent ungrouping of HRs 20

CCHS PUMF – disclosure control • Geography / HR population size • Minimum population size of 70, 000 per health region § 19 HRs grouped into 9 § 3 Territories not grouped this PUMF • Results in 98 Health Regions or HR groupings • Age of respondent • 5 year age groups 20 -24 -> 75 -79 • 12 -14, 15 -17, 18 -19 § Supports research on Body Mass Index (BMI) and new physical activity content (PAA/PAY) • Other indirect identifiers grouped or masked to prevent disclosure 21

CCHS 15 -16 PUMF: Poisson bootstrap weights • Previous PUMFs did not include bootstrap weights • 2015 -2016 PUMF includes Poisson bootstrap weights • Each weight for each replicate is generated independently • All bootstrap weights are strictly positive • The Poisson bootstrap does not pose confidentiality concerns 22

PUMF Package • Data • Bootstrap weights • Documentation • • • User guides CV tables Data Dictionary Derived Variables Errata Questionnaire • Beyond 2020 23

2021 CCHS Redesign Objectives • Transition to Electronic Questionnaires • Revisit content and develop a new content plan • Revisit the methodology • Increase administrative data holdings • Modernize with Statistics Canada • 2020 Pilot 24
