It may not be reported consistently from survey to survey. At the level of each response category, most categories show an even greater degree of inconsistency. <strong>Post</strong> Enumeration <strong>Survey</strong> (<strong>PES</strong>)
<strong>Statistics</strong> <strong>South</strong> <strong>Africa</strong> 70 8.7 Summary of content error analysis The characteristics 'population group', 'age' and 'sex' show a low level of variability between the census and the <strong>PES</strong>. They can be expected to be measured reliably from survey to survey. The variables 'relationship to head of household', 'marital status' (combining categories)' show a moderate level of variability, which might be indicative of a need for clearer concept definitions and wording, and more probing.
