USING THE TABLEBUILDER
CONTINUOUS DATA ITEMS
Some continuous data items are allocated special codes for certain responses (e.g. 9999 = 'Not applicable'). When creating ranges for such continuous items for use in the TB, these special codes will NOT be included in these ranges. Therefore, the total shown only represents 'valid responses' of that continuous data item rather than all responses (including special codes).
The following table shows the responses for 'Weekly personal income from all sources' by 'Sex of person'. The continuous values of the data item are contained in the 'A valid response was recorded' row. If the actual continuous values are to be displayed, then it is necessary to create a range for them.
Here is the same table with a range applied for the continuous values of 'Weekly personal income from all sources' (Wkly Pers Inc Example). Note that the numbers of respondents for the other responses 'Not stated' and 'Refusal' no longer contribute to the table.
Any special codes for continuous data items are listed in the Data Item List in the Downloads tab.
ZERO VALUE CELLS
Tables generated from sample surveys will sometimes contain cells with zero values because no respondents that satisfied the parameters of the cell were in the survey. This is despite there being people in the population with those characteristics. That is, the cell may have had a value above zero if all persons in scope of the survey had been enumerated. This is an example of sampling variability which occurs with all sample surveys. Relative standard errors cannot be generated for zero cells. Whilst the tables may include cells with zero values, the ABS does not publish such zero estimates and recommends that TB clients do not use these data either.
MULTI–RESPONSE DATA ITEMS
For the data item in the example above, a question is asked in the survey which collects all the reasons a person went to a hospital emergency department instead of a GP on the most recent occasion. As a person may indicate more than one reason, this means they can supply multiple responses to this data item.
When a multi-response data item is tabulated, a person is counted against each category for which they have provided a response (e.g. each reason a person gives for going to an emergency department and not seeing a GP for treatment).
Similar to a single response data item, a person not within the appropriate population will fall into the ‘Not applicable’ category (e.g. a person who did not visit an emergency department is not asked about their reasons for not seeing a GP and is therefore considered ‘Not applicable’ for this data item).
Therefore, each person in the applicable population is counted at least once, while some persons are counted multiple times. Multi–response data items can be identified by the initials 'MR' in the data item list, which can be accessed from the Downloads tab. The total for multi-response data items is therefore less than or equal to the sum of its components. In the example below, the sum of the components is 18,571.9 whereas the total population is 18,058.9.
NOT APPLICABLE CATEGORIES
Most data items include a 'Not applicable' category. The 'Not applicable' category comprises those respondents who were not asked a particular question(s) and hence are not applicable to the population to which the data item refers. In the example above, 15,593,500 people did not visit a hospital emergency department and therefore are not applicable to the data item. The classification value of the 'Not applicable' category, where relevant, is shown in the data item list (see the data item list in the Downloads tab).
