The survey was designed and implemented in partnership with national Aboriginal organizations. This is the third time the Aboriginal Peoples Survey has been carried out by Statistics Canada; the first time was in 1991 and the second was in 2001. The data from both the 1991 and 2001 APS were widely used. An extremely important user of the 1991 data was the Royal Commission on Aboriginal Peoples (RCAP). They used the data as a primary source of demographic, social and economic data for their final report and related research studies. The Commission's final report recommended that the APS be conducted regularly to monitor the demographic and social conditions of Aboriginal peoples. Data from the 1991 and 2001 APS have also been used by Aboriginal organizations, community planners, service providers, governments and researchers to inform decision-making (program/policy planning and development), to improve services for Aboriginal peoples and to support academic research. With the release of the 2006 data, the APS can also be used to track changes over time and provide an up-to-date picture of the situation of Aboriginal peoples. The APS provides data about Aboriginal (Inuit, Metis and off-reserve First Nations) people 6 years of age and over living in urban, rural and northern locations across Canada. The APS survey was funded by a Consortium of federal departments including Indian and Northern Affairs Canada (INAC), Human Resources and Skills Development Canada (HRSDC), Health Canada (HC), Canada Mortgage and Housing Corporation (CMHC) and Canadian Heritage (CH). This document was developed in order to facilitate the use of the Public Use Microdata File (PUMF) for the 2006 Aboriginal Peoples Survey (Children and Youth component). It describes the survey, its methodology, data quality, and other issues related to data analysis and dissemination. It also describes how to use the PUMF correctly. The PUMF should be used together with the data dictionary, which includes the survey questions, derived variables, and frequency distributions of all the variables. For more information on the concepts and methods used for the Aboriginal Peoples Survey, the publication Aboriginal Peoples Survey, 2006: Concepts and Methods Guide, included with this product, may be consulted. Any additional questions about the APS PUMF or its use should be directed to: Client Services Social and Aboriginal Statistics Division Statistics Canada Jean Talon Building, 7th floor 170 Tunney's Pasture Driveway Ottawa, Ontario, K1A 0T6 Telephone: (613) 951-5979 Fax: (613) 951-0387 E-mail: sasd-dssea@statcan.gc.ca Page 2 Aboriginal Peoples Survey, 2006 - User's Guide to the Public Use Microdata File (Child and Youth) 1. Data files and associated files The Aboriginal Peoples Survey collected data on Aboriginal people 6 years of age and over (First Nations people living off reserve, Metis and Inuit) in urban, rural and northern locations throughout Canada. Although people living on reserve were not included in the provinces, all First Nations people, Metis and Inuit living in the territories were included. The Children and Youth PUMF contains data from the Children and Youth component of the survey described in section 4.2.2 of the Concepts and Methods Guide. In order to ensure the non-disclosure of confidential information, the level of detail of the PUMF is not as fine as that of the analytical files kept by Statistics Canada. Actions were also taken to make the microdata file more secure from disclosure of confidential information. These actions concern the geography included in the file, survey weights, overlaps with other PUMFs being published, exclusion of variables, grouping of categories for some variables, capping of some extreme numerical values, as well as identification of unique records at risk and rare occurrences. As a result, the PUMF for Aboriginal children and youth contains 13,238 records. Each record represents one respondent and contains 222 variables, providing data from various sections of the APS questionnaire as well as from the Census. A complete list of these variables is provided in the data dictionary. The data file is provided in flat text file format. Also provided are files of "cards" or commands which facilitate the use of the data file by two widely used analysis programs: SAS (Statistical Analysis System) and SPSS (Statistical Package for the Social Sciences). These cards are provided in both English and French versions, and include the commands required to read the text file into the required format, as well as the formats and labels for all the variables on the file. Also provided in English and French are the data dictionaries. For step-by-step instructions on how to use the SAS or SPSS cards to run the data, please consult Appendix A. 2. Estimation In a sample survey, each responding unit represents not only himself/herself, but also other persons who were not sampled. Consequently, a weight is associated with each responding unit to indicate the number of persons that this person represents. This weight must be used for all estimations. For example, in a simple random sample of 2% of the population, each person represents 50 persons in the population. The initial weight is then adjusted for such things as non-response and discrepancies between the characteristics of the sample and known totals for the target population (post-stratification adjustment). The number of persons represented by a given responding unit is what is known as the unit's weight or weighting factor. A weighting factor is included in the APS PUMF: WTPP: This is the weight for analysis with respect to persons, that is, for calculating estimates of the number of persons (included in the target population) with one or more specified characteristics. WTPP should be used to calculate all estimates. For example, to estimate the number of children who Page 3 Aboriginal Peoples Survey, 2006 - User's Guide to the Public Use Microdata File (Child and Youth) were 6 to 8 years old on October 31, 2006, it is necessary to sum the WTPP values for all records that include this characteristic (DAGEYRSG=1). 2.1 Weighting Calculating the survey weights for the APS was a seven-stage process: - Initial weights - Adjustment for overlap with other surveys - Adjustment for units selected in ACS - Adjustment for adult-child and child-adult conversion - Adjustment for out of scope units - Adjustment for nonresponse - Post-stratification adjustments More information about the weighting process is found in section 7.3 of the Concepts and Methods Guide. To produce the PUMF, an eighth step was necessary. Because the PUMF is a subsample of the APS children and youth sample, additional adjustments had to be made to the weights of units in the PUMF to take account of the units removed. To do this, the weight obtained in stage 7 was first adjusted to take into account the records removed from the file because of overlap with other surveys (post-censal surveys and the Census PUMF). Then, these were multiplied by the subsampling weight and a new post-stratification was needed in order to adjust the census counts. Finally, some random noise was added to the resulting weight as an additional measure to ensure confidentiality. 2.2 Weighting guidelines The weight assigned to each record underwent numerous adjustments so that the sum of the weights of responding units would better represent the target population. Weighting of the data ensures that the APS sample is representative of the target population even if the sampling rate differs widely from one individual to another. The use of the weights is essential for all analyses that use the survey data. Users should not disseminate any unweighted total or perform analyses based on unweighted survey results. Sampling rates and non-response rates vary considerably from one stratum to another, and non response rates also vary according to demographic characteristics. Therefore, unweighted sample counts cannot be considered as representative of the population targeted by the survey. 2.3 Types of Estimation Using APS data, two types of "simple" estimates can be calculated: qualitative estimates (estimates of numbers or proportions of people with certain attributes or characteristics) and quantitative estimates (estimates of quantities such as the average income per individual, for instance). 2.3.1 Qualitative Estimates Qualitative estimates are estimates of the number or percentage of people in the population targeted by the survey who have a certain characteristic or fall into a defined category. The values of these variables represent a quality rather than a quantity. An example of a qualitative estimate is the number or proportion of people whose state of health was reported as "Excellent". Qualitative estimates can be obtained by summing the final weights of all records with the characteristic(s) of interest. Proportions and ratios of the form Y/W are obtained by following the steps below.
