2001 Census Ethnicity Reports - Report on Coding of Any Mixed Background

3. Tick and Text Data (T&T)

Some clue as to what the form-filler entered on the form may be given by the labels for the detailed codes in Appendix B. However, these pre-determined codes won’t necessarily accord with the information that the form-fillers actually provided. To examine in detail what form-fillers actually ticked and wrote on the form, we need to look at ancillary information about how Census questions were answered, which was recorded in a special ‘tick and text’ database during the process of data capture. In particular, for the question on ethnicity, the database records the presence or otherwise of a tick in each of the 14 tick boxes and any text captured in the 5 write-in boxes.

T&T data was captured for 12,066 of those coded as being of ‘Any Mixed background’. The number for each detailed ethnic code is shown in the column in Appendix B headed ‘In T&T database’. The shortfall of 698 is largely explained by the One Number Census (ONC) process which added records to the database to account for under-enumeration and for which no T&T data was generated. The ONC added 647 persons to ‘Any Mixed background’. The remaining 51 are likely to be caused by corrections to form identification numbers being made to the main database without corresponding changes to the T&T data, thus preventing the T&T data being retrieved alongside the main data records.

Table 2 shows combinations of tick and text used. The table shows that, for 489 persons, there was no box ticked or text written-in on the form. The ethnicity of such people would have been imputed as part of the process of edit and imputation. Imputation was done by finding donor records that matched on variables such as Country of Birth, Age, Marital Status, Religion and the Ethnic Group of other household members.

Table 2 also shows that there were some 871 cases where no text was provided but a single tick box was ticked. In all but 15 of these, the box ticked was the one in Section B of the Census form ('Mixed'). There were also 930 persons with no text but more than one box ticked. In over 9 out of 10 of these cases, the boxes ticked included box 5 'Any Mixed background'.
