Image: spreadsheet DATA ITEM LIST


The TableBuilder Data Item List shows the items available for use and shows what each variable value indicates in the data.

Each sheet of the Data Item List indicates a level of data (Household, Persons in Household, Conditions) or a grouping of like data about a selected person (Demographics, Education, Employment, Health, Risk Factors, Physical Measurements, Alcohol).

A glossary of definitions for the data items can be found in the Explanatory Notes of Australian Health Survey: Users' Guide, 2011-13 (cat. no. 4363.0.55.001).

For confidentiality and/or usability reasons some data item values have been collapsed and/or restricted for use on the TableBuilder.

Weight Variables
There is a weight variable on each level of the NHS file on the TableBuilder. They can be found under the 'Summation Options' heading and are called the following:

Household weights
Household level - Households - Benchmarked
All Persons in Household level - All Persons in Household

Person weights
Selected Person level - Selected Persons - Benchmarked
Alcohol Day level - Alcohol Day
Alcohol Type level - Alcohol Type
Actions level - Actions
Conditions level - Conditions
Medications level - Medications

Using Weights
The NHS is a sample survey. To produce estimates for the in-scope population you must use weight fields in your tables. The weight fields are listed below. In TableBuilder they can be found under the Summation Options category in the left hand pane. If you do not select a weight field, TableBuilder will use Person Weight - Selected Persons by default. This will give you estimates of the number of persons. To produce estimates of the number of households you would have to add Households from the Household level to your table.

The Household Weight was benchmarked to the Household Level while the Person Weight was benchmarked to the Selected Person level. When using a Weight/Summation from a level that is different to that of the variables in the table please be careful in interpreting the results.

For example, a table that uses the 'Number of Condition level' weight will not show the number of persons in a cell but rather the number of conditions.

You can use a weight field with classificatory fields from other levels but should take care when interpreting the results. Below are some examples which you can use as a guide.
