*Subject to rounding error
*The undercount rate for undetermined population group is excluded from this table
The undercount for males (15,9%) is higher than that for females (13,4%). 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 Africans (9,9%).
