The following data cubes present information about the use of, and demand for, child care for children aged 0–12 years. Statistics in these data cubes were obtained from the 2005 Child Care Survey. Information is also presented on the working arrangements of parents with children aged 0–12 years. Not all states or territories are represented in each table due to data quality concerns.
ABOUT THIS REISSUE
This re-issue corrects an error in family estimates. An error in family weights resulted in the previously-released estimates for June 2005 overstating, by about 7%, the total number of families with children under 13 years in tables 11, 23 and 30. The proportions shown in these tables are only slightly affected by that error.
The family weighting error does not affect child level estimates in the other tables.
Not all publication tables have been released at state level due to a need to maintain data quality and respondent confidentiality. The state tables that have been amended due to the reweighting are:
NSW Table 11, Table 23
Qld Table 11, Table 23
SA Table 11, Table 23
VIC Table 11, Table 23
WA Table 11, Table 23
ACT Table 23 only
Tas Table 23 only
There are no published tables at territory level for the Northern Territory.
RELIABILITY OF ESTIMATES
Since the estimates in these data cubes are based on information obtained from occupants of a sample of dwellings, they are subject to sampling variability. That is, they may differ from those estimates that would have been produced if all dwellings had been included in the survey. One measure of the likely difference is given by the standard error (SE), which indicates the extent to which an estimate might have varied by chance because only a sample of dwellings was included. There are about two chances in three (67%) that a sample estimate will differ by less than one SE from the number that would have been obtained if all dwellings had been included, and about 19 chances in 20 (95%) that the difference will be less than two SEs. Another measure of the likely difference is the relative standard error (RSE), which is obtained by expressing the SE as a percentage of the estimate.
It is impractical to print the SE of each estimate in the data cubes. Instead, two tables of RSE cutoffs are provided, as follows, to enable readers to determine the reliability of an estimate
|Cutoffs for estimates of number of children|
|RSE of 25% to 50%||9300||8100||7400||4400||4800||2500||4300||2400||7700|
|RSE over 50%||2000||1900||1500||1000||900||600||900||600||1600|
|Cutoffs for estimates of number of families|
|RSE of 25% to 50%||7132||6018||5269||3166||3602||2117||1874||1981||5361|
|RSE over 50%||1553||1394||1164||755||807||542||499||455||1100|
