Canadian Community Health Survey, 2011-2012: Annual Component

The Canadian Community Health Survey (CCHS) is a cross-sectional survey that collects information related to health status, health care utilization and health determinants for the Canadian population. It surveys a large sample of respondents and is designed to provide reliable estimates at the health region level. In 2007, major changes were made to the CCHS design. Data is now collected on an ongoing basis with annual releases, rather than every two years as was the case prior to 2007. The survey's objectives were also revised and are as follows: • support health surveillance programs by providing health data at the national, provincial and intra-provincial levels; • provide a single data source for health research on small populations and rare characteristics; • timely release of information easily accessible to a diverse community of users; and • create a flexible survey instrument that includes a rapid response option to address emerging issues related to the health of the population. The CCHS data is always collected from persons aged 12 and over living in private dwellings in the 115 health regions covering all provinces and territories. Excluded from the sampling frame are individuals living on Indian Reserves and on Crown Lands, institutional residents, full-time members of the Canadian Forces, and residents of certain remote regions. The CCHS covers approximately 98% of the Canadian population aged 12 and over. The CCHS produces three types of microdata files: master files; share files; and public use microdata files (PUMF). The characteristics of each of these files are presented in the User Guide. The PUMF is released every two years and contains two years of data.

加拿大社区健康调查（Canadian Community Health Survey, 简称CCHS）是一项横断面调查，旨在采集加拿大人群的健康状况、医疗服务利用情况及健康决定因素相关信息。该调查依托大样本受访者开展，设计目标为实现在健康区域层面提供可靠的统计估计值。
2007年，CCHS的调查方案迎来重大调整：当前数据采集采用持续收集、年度发布的模式，而非2007年之前的每两年一次。同时，该调查的目标也进行了修订，具体如下：
• 通过提供国家级、省级及省内层面的健康数据，支撑健康监测项目开展；
• 为小体量人群及罕见特征相关的健康研究提供统一数据源；
• 及时发布信息，便于多元化用户群体便捷获取；
• 打造灵活的调查工具，增设快速响应选项，以应对与人群健康相关的新兴议题。
CCHS的数据始终采集自覆盖加拿大所有省和地区的115个健康区域内、居住于私人住宅中的12岁及以上人群。其抽样框排除以下人群：居住在印第安保留地与王室土地上的个体、机构收容居民、加拿大武装部队现役全职人员，以及部分偏远地区居民。CCHS覆盖了约98%的12岁及以上加拿大人群。
CCHS共生成三类微数据文件：主文件（master files）、共享文件（share files）以及公共使用微数据文件（Public Use Microdata Files, 简称PUMF）。各类文件的具体特征详见《用户指南》。PUMF每两年发布一次，包含两年的调查数据。
