The Participation and Activity Limitation Survey (PALS) is a post-censal survey which collects information about persons whose everyday activities are limited because of a health-related condition or problem.PALS is a post-censal survey because it uses the census as a sampling frame to identify its target population. For example: the 2001 Census questionnaire included two general questions on activity limitations and long-term disabilities. The 2001 PALS respondents were selected through the use of the census information on age, geography and the responses to these two general questions.
