When population groups are compared, persons under the population group 'Other' were undercounted at a significantly higher rate than the other population groups, with a rate of 23,2%, followed by Whites with a rate of 15,6% (see Figure 8 below). There is no significant difference in undercount among the coloured and Indian/Asian groups. The lowest undercount was observed among Black <strong>Africa</strong>ns (9,9%). <strong>Post</strong> Enumeration <strong>Survey</strong> (<strong>PES</strong>)
