Question
Would anyone know where to find actual numbers of high school graduates in the 1930s? We have a student looking for this information. He is looking for Canada and by province if possible.
Response
The Education Division's information dates back to the 1970s at the earliest.

The Inter-Corporate Ownership 2006-Q2 (ICO)
The Inter-Corporate Ownership 2006-Q2
The Inter-corporate ownership directory is the most authoritative and comprehensive source of information available on corporate ownership, a unique directory of "who owns what" in Canada. It tracks the ownership of the largest Canadian corporations and provides up-to-date information reflecting recent corporate takeovers and other substantial changes. Ultimate corporate control is determined through a careful study of holdings by corporations, the effects of options, insider holdings, convertible shares and interlocking directorships. The information that is presented is based on non-confidential returns filed by Canadian corporations under the Corporations Returns Act. The Inter-corporate ownership directory now lists more than 95,000 corporations.
The data are presented in an easy-to-read tiered format, illustrating at a glance the hierarchy of subsidiaries within each corporate structure. The entries for each corporation provide both the country of control and the country of residence. As well, the inclusion of the Standard Industrial Classification code enables study by industrial sector.

CCHS 2.2 Synthetic Files
Questions
1. When will the CCHS 2.2 synthetic files be available?
2. The userguide (page 20, section 5.7, second paragraph) states:
"The reader should however note that the variable "aboriginal status" has been removed from the Public Use Microdata File for confidentiality purposes. This variable can only be accessed through the use of the master file which resides at Statistics Canada and in the Regional Data Centres or through the use of the share file in the provincial Ministries of Health, at Health Canada and at the Public Health Agency of Canada."
What is the share file? Does the researcher have access through the Saskatchewan Dept. of Health? Please note it is the aboriginal status variable that the researcher requires.
3. In the userguide (page 69, section 12.4, final paragraph) remote access service is described. We are wondering if this exists when there isn't (yet) a synthetic file?
Furthermore, the paragraph refers to the user as the 'purchaser'; are we correct in assuming DLI users are 'purchasers' via the DLI licence. As you know, there are no RDCs in Saskatchewan.
Answers
Because of the number of files resulting from the 2.2 survey (7 files) it is not possible, at this point, to create a synthetic files like it was done for the other surveys. Users would have to do some linkages between the 7 files and the chance of encountering problems and errors is too high. Methodologists have been asked to look at a possible strategy on what can be done in this case. This means, for the time being, that it is not possible to access these files. We will update you as soon as we get news from Methodology to let you know if we will be able or not to resolve that issue.
The share file is the file that we provide to the Provincial Health Department and Health Canada with the permission of the respondents(records from respondents who refuse to have their data shared with specific partners are taken out of the share file and appears only on the master file). Researchers are not given access to the share file in Health Departments. It's not part of the sharing agreements and the only way for a researcher to access the master file is through remote access or by presenting a project through the RDCs. Because there is no synthetic file at this point for 2.2, the remote access does not exist. We certainly hope methodologists do find a solution to that issue but until then, there is no remote access to 2.2.
Yes, through the DLI license, the DLI users are purchasers and yes that variable "aboriginal status" has been removed for confidentiality purposes and this is after discussions with the Micro data Release Committee who ensure that confidentiality is not threatened in any way.

Historical stats on religion and ethnicity
Question
A religion grad student at Concordia is looking for the following: population of Jews and Arabs in Canada as a whole and in the Montreal CMA (or, if not available, for the province of Quebec) for the 1901-2001 period. She would also like to have the number of Muslims for the same geographic areas (Canada and Montreal CMA or province of Quebec) and the same period.
I suppose it would be possible to gather data from the individual census but the student does not have much time to do that and would much prefer ready-made historical statistic. Unfortunately, I suspect those do not exist for the categories mentioned above. The only historical data I have been able to find so far is the Jewish population (CANSIM Table 075-0016).
Answer
For some of the years there was no data for certain categories and there was no data for Montreal. StatsCan does not have any publication for prior to 1971. I will be contacting subject-matter for any additional information, but I know from past experience they also do not have historical data at their fingertips unless they have done an historical study.
