DATA ERRORS

Please be advised that errors have been detected with four variables and the 
resulting data on this CD-ROM product.  

The two variables, FULL-TIME OR PART-TIME WEEKS WORKED IN 1995 BY THE MALE 
SPOUSE, MALE COMMON-LAW PARTNER, MALE LONE PARENT OR MALE NON-FAMILY PERSON 
(FPTWKM) and FULL-TIME OR PART-TIME WEEKS WORKED IN 1995 BY THE FEMALE SPOUSE, 
FEMALE COMMON-LAW PARTNER, FEMALE LONE PARENT OR FEMALE NON-FAMILY PERSON 
(FPTWKF), were found to contain unjustifiably high counts in their "Not 
applicable" categories. The source code used in the creation of the variables 
was examined and it was found to be in error. The logic used in the derivation 
of the variables lacked specificity and, as a result, families may have been 
erroneously classified according to the characteristics of a member to whom 
the concept did not apply.  

Furthermore, the code for LEGAL MARITAL STATUS OF THE MALE COMMON-LAW PARTNER, 
MALE LONE PARENT OR MALE NON-FAMILY PERSON (MARSTLM) and LEGAL MARITAL STATUS 
OF THE FEMALE COMMON-LAW PARTNER, FEMALE LONE PARENT OR FEMALE NON-FAMILY 
PERSON (MARSTLF) incorrectly assigned a large number of units to the divorced 
category, and this thereby affected the quality of the remaining categories.

The discrepancies have now been corrected, and the present data for these 
variables has been verified to be correct. Also, all other variables have been 
completely re-verified and are correct on this CD-ROM product. No other problem 
variables were found on either the 1996 Census PUMF Households and Housing or 
Individuals Files. 

In addition, the control counts for the above variables were updated in the 
1996 PUMF Families File User Documentation. 


DATA QUALITY INFORMATION INCONSISTENCIES 

Inconsistencies were also identified with some of the data quality information 
found on all three 1996 Census PUMF files. After a thorough review of the data 
quality information, all errors relating to data quality information have now 
been corrected. The following is a list of the inconsistencies that were 
identified:

1. Errors were identified in the "Quality of Estimates" tables found on all 
three 1996 PUMF files. An incorrect formula was used for calculating the 
coefficient of variation in the case of quantitative variables (e.g. income) 
for these tables. The "Quality of Estimates" tables can be found in Chapter III 
(Sampling Method and Data Quality) of the 1996 PUMF User Documentation.
 
2. Since Example 4 in Chapter III uses results obtained from the "Quality of 
Estimates" tables, this example was also incorrect on all three files.

3. Further to the main error mentioned above, some inconsistencies were also 
identified between the English and French versions of the "Quality of Estimates" files.

4. In addition to the User Documentation, the following "Quality of Estimates" 
files were also affected by the problems noted above.

CENSUS FAMILY TYPE (CFTYPE) Explanatory Note

An explanatory note has been appended to the description of the CENSUS FAMILY 
TYPE (CFTYPE) variable in the 1996 Census PUMF Families File User Documentation. 
The appended note provides additional clarification regarding conceptual differences 
which can occur when the CFTYPE variable is cross-tabulated with the PRIMARY 
HOUSEHOLD MAINTAINER INDICATOR FOR THE MALE SPOUSE, MALE COMMON-LAW PARTNER, 
MALE LONE PARENT OR MALE NON-FAMILY PERSON (HMAINM) or PRIMARY HOUSEHOLD MAINTAINER 
INDICATOR FOR THE FEMALE SPOUSE, FEMALE COMMON-LAW PARTNER, FEMALE LONE PARENT OR 
FEMALE NON-FAMILY PERSON (HMAINF) variables in the 1996 PUMF Families File.   
For further information, please refer to the description of the CFTYPE variable 
in the 1996 PUMF Families File User Documentation.
