A new approach to disability data: changes between the 1991 Health and Activity Limitation Survey (HALS) and the 2001 Participation and Activity Limitation Survey (PALS)Abstract The 2001 Participation and Activity Limitation Survey (PALS) is a post-censal survey of adults and children whose everyday activities are limited because of a condition or health problem. A sample of those persons who answered "Yes" to the 2001 Census disability filter questions were included in the PALS survey population. Approximately 35,000 adults and 8,000 children living in private, and some collective, households in the 10 provinces were selected to participate in the survey. The data were collected in the fall of 2001. The survey was last conducted after the 1991 Census under the title of the 1991 Health and Activity Limitation Survey (HALS). This report presents an overview of the methodological and content changes between the 1991 HALS and the 2001 PALS. The major differences include new census disability filter questions, a new sampling plan and new questionnaire content.
