Reliability of estimates

As the survey was conducted on a sample of households in Australia, it is important to take account of the method of sample selection when deriving estimates from the detailed microdata. This is important as a person's chance of selection in the survey varied depending on the state or territory in which the person lived. If these chances of selection are not accounted for by use of appropriate weights, the results could be biased.

Each person record has a main weight (FINWTPC). This weight indicates how many population units are represented by the sample unit. When producing estimates of sub-populations from the detailed microdata, it is essential that they are calculated by adding the weights of persons in each category and not just by counting the sample number in each category. If each person’s weight were to be ignored when analysing the data to draw inferences about the population, then no account would be taken of a person's chance of selection or of different response rates across population groups, with the result that the estimates produced could be biased. The application of weights ensures that estimates will conform to an independently estimated distribution of the population by age, by sex, etc. rather than to the distributions within the sample itself.

It is also important to calculate a measure of sampling error for each estimate. Sampling error occurs because only part of the population is surveyed to represent the whole population. Sampling error should be considered when interpreting estimates as this gives an indication of accuracy and reflects the importance that can be placed on interpretations using the estimate. Measures of sampling error include standard error (SE), relative standard error (RSE) and margin of errors (MoE). These measures of sampling error can be estimated using the replicate weights. The replicate weight variables provided on the microdata are labelled WPC01XX, where XX represents the number of the given replicate group. The exact number of replicates will vary depending on the survey but will generally be 30, 60 or 200 replicate groups. As an example, for survey microdata with 30 replicate groups, you will find 30 person replicate weight variables labelled WPC0101 to WPC0130.

Using replicate weights for estimating sampling error

Overview of replication methods

How to use replicate weights

To calculate the standard error of any statistic derived from the survey data, the method is as follows:
1.   Calculate the estimate of the statistic of interest using the main weight.
2.   Repeat the calculation above for each replicate weight, substituting the replicate weight for the main weight and creating G replicate estimates. In the example where there are 30 replicate weights, you will have 30 replicate estimates.
3.   Use the outputs from step 1 and 2 as inputs to the formula below to calculate the estimate of the Standard Error (SE) for the statistic of interest.

$SE_{(y)}=\sqrt {{G−1\over G} \sum_{g=1}^{G} (y_{(g)}−y)^2}$

[Equation 1]

$G = \text{ Number of replicate groups}$

$g = \text{the replicate group number}$

$y_{(g)} = \text{Replicate estimate for group } g\text{, i.e. the estimate of }y \text{ calculated using} \\ \qquad \quad \text{the replicate weight for }g$

$y = \text{the weighted estimate of }y \text{ from the sample}$

From the replicate variance you can then derive the following measures of sampling error: relative standard error (RSE), or margin of error (MOE) of the estimate.

$Relative\;Standard\; Error\; \normalsize (RSE) = \frac{{SE}}{{Estimate}}$

[Equation 2]

$Margin\;of\;Error\; (MoE) = 1.96 \;\times\; SE$

[Equation 3]

An example in calculating the SE for an estimate of the mean

Suppose you are calculating the mean value of earnings, y, in a sample. Using the main weight produces an estimate of $500.
You have 5 sets of Group Jackknife replicate weights and using these weights (instead of the main weight) you calculate 5 replicate estimates of $510, $490, $505, $503, $498 respectively.

To calculate the standard error of the estimate you will substitute the following inputs to equation [1]

$G = 5$

$y = 500$

$g = 1, y_{(g)} = 510$

$g = 2, y_{(g)} = 490$

…

$\normalsize SE (y)=\sqrt{\frac{5-1}{5} \sum_{g=1}^{5}(y_{(g)}-500)^{2}}$

$\normalsize SE (y)=\sqrt{\frac{4}{5} ((510-500)^{2} + (490-500)^{2} + (505-500)^{2} + (503-500)^{2} + (498-500)^{2}}$

$\normalsize SE (y)=\sqrt{\frac{4}{5} \times 238}$

$\normalsize SE (y)=13.8$

To calculate the RSE you divide the SE by the estimate of y ($500) and multiply by 100 to get a %

$\normalsize RSE(y) = {\frac{13.8}{500}\times100}$
$\normalsize RSE(y) = 2.8\%$

To calculate the margin of error you multiply the SE by 1.96

$\normalsize Margin\;of \;Error (y)=13.8 \times 1.96$
$\normalsize Margin\;of\;Error (y)=27.05$

Weights

When tabulating data in TableBuilder, person weights are automatically applied to the underlying sample counts. Weighting is the process of adjusting results from a sample survey to infer results for the total population. To do this, a 'weight' is allocated to each sample unit. The weight is the value that indicates how many population units are represented by the sample unit.

Table populations

The population relevant to each data item is identified in the data item list and should be kept in mind when extracting and analysing data. The actual population estimate for each data item is equal to the total cumulative frequency minus the 'Not applicable' category.

Generally, all populations, including very specific populations, can be 'filtered' using other relevant data items. For example, if the population of interest is 'Employed persons', any data item with that population (excluding the 'Not applicable' category) could be used.

Not applicable categories

Most data items included in the TableBuilder file include a 'Not applicable' category. The classification values of these 'Not applicable' categories, where relevant, are shown in the data item list in the Data downloads section. The 'Not applicable' category generally represents the number of people who were not asked a particular question or the number of people excluded from the population for a data item when that data was derived (e.g. Year of Arrival in Australia is not applicable for people born in Australia).

Continuous data items

TableBuilder includes a number of continuous variables:

They can have a response value at any point along a continuum.
Some continuous data items are allocated special codes for certain responses (e.g. 000 = 'Not applicable').
When creating ranges in TableBuilder for such continuous items, special codes will automatically be excluded. Therefore the total will show only 'valid responses' rather than all responses (including special codes).
Continuous items with special codes have a corresponding categorical item on the Person level that provides the ability to display data for the special code.
Any special codes for continuous data items are listed in the data item list in the Data downloads section.

Multiple-response data items

A number of data items allow respondents to report more than one response. For these items, a person is counted against each category they responded to and consequently the sum of the categories may be different to the total. An example of such a data item is 'Long-term health conditions'. For this data item, respondents can report more than one of the Long-term health conditions they had, that lasted, or was likely to last, six months or more.

Multiple-response data items are identified in the data item list, as they include 'multiple response' in the data item label. The data item list can be accessed from the Data downloads section.

Confidentiality

A confidentiality process called perturbation is applied to the data in TableBuilder to avoid releasing information that may lead to the identification of individuals, families, households, dwellings or businesses. See Confidentiality in the TableBuilder user guide.
