Persons appearing in both census and PES questionnaires for the same household were matched
according to their primary variables, i.e. sex, date of birth, age and population group. Tolerance limits for
age for matched persons were applied in the following manner:
Table 5: Tolerance limits for age
Age (years) Tolerance
Under 10 -2 to +2 years
10–19 -3 to +3 years
20–39 -5 to +5 years
40–59 -7 to +7 years
60+ -10 to +10 years
4.3.2 Capturing and assigning of initial match status
Capturing involved the capturing of PES and census information on a capturing tool which formed part of
the computer-assisted manual matching system. Information for non-matched households and persons
was also captured. Quality assurance measures applied during this phase included the checking of what
had been matched and captured by the Matching Clerk against the information on PES and census
questionnaires. Inspection of captured information was done by the Matching Supervisor and Quality
Assurance Monitor. The process of assigning an initial match status and moving status for households
and persons was automated, and done simultaneously with the capturing process. The computerassisted
matching phase produced three matching outcomes for households and seven for persons.
Households
Household Initial Match Status
1 = Matched
2 = Possible match
3 = Non-match
All 'Possible match' and 'Non-match' cases were considered 'unresolved' and were reviewed in order to
determine if they required field follow-up (reconciliation) to determine their final status.
