TECHNICAL NOTE DATA QUALITY INDICATORS


DATA QUALITY

1 When interpreting the results of a survey it is important to take into account factors that may affect the reliability of estimates. The survey procedures as well as sampling and non-sampling errors should be considered. Examination of the following quality indicators will assist users in determining fitness for purpose of the Survey of Motor Vehicle Use (SMVU).


SAMPLING ERROR

2 Estimates in this publication are based on information collected for a sample of registered motor vehicles, rather than a full enumeration, and are therefore subject to sampling error. They may differ from the estimates that would have been produced if the information had been obtained for all registered motor vehicles. Examples of the sampling error for this release are included in this Technical Note.

3 The sampling error associated with an estimate can be derived from the sample results. One measure of sampling error is given by the standard error, which indicates the extent to which an estimate might have varied by chance because only a sample of vehicles was included. There are about two chances in three that a sample estimate will differ by less than one standard error from the figure that would have been obtained if all vehicles had been included, and about 19 chances in 20 that the difference will be less than two standard errors.

4 Another measure of sampling variability is the relative standard error (RSE) which is obtained by expressing the standard error as a percentage of the estimate to which it refers. The RSE is a useful measure in that it provides an immediate indication of the percentage error likely to have occurred due to sampling. In the data cubes for this release, estimates are presented in the tables side by side with their RSEs.

5 The RSEs relating to 2014 estimates contained in Table 4 of the data cubes of this release are shown in the following table.

(a) These RSEs relate to the estimates in Table 4.


6 As an example of the use of an RSE, the 2014 estimate for total kilometres travelled by passenger vehicles registered in Australia is 176,805 million kilometres (Table 4 of the data cubes). The rounded RSE for this estimate is 3.15%, as shown above. Therefore, the standard error for the estimated total kilometres travelled by passenger vehicles is 5,569 million kilometres (3.15% of 176,805 million kilometres). Standard errors can be used to construct confidence intervals around the estimates. There are about two chances in three that the figure obtained if all vehicles had been included, would have been in the range 171,236 million kilometres to 182,374 million kilometres (a range of one standard error above and below the survey estimate). There are about 19 chances in 20 that the figure would have been in the range 165,667 million kilometres to 187,943 million kilometres (a range of two standard errors above and below the survey estimate).

7 It is important to note that estimates at more detailed levels than the above are subject to higher RSEs and therefore are less reliable.

(a) These RSEs relate to the estimates in Table 23.


9 Tables 1, 2 and 3 for this release contain estimates for earlier years.

10 The standard error for the movement between two years can be approximated using the following formula Equation: EQ1_SEwhere Equation: EQ2is an estimate of total of the variable of interest, obtained from the 1st time point Equation: EQ3is an estimate of total of the same variable of interest, obtained from the 2nd time point Equation: EQ4is an estimate of movement of the total of the variable of interest from the 1st time point to the 2nd time point, ie Equation: EQ5

11 For total kilometres travelled by type of vehicle from the 2010 and 2014 SMVUs, the standard errors of the movements and the estimates from which they are derived are shown in the following table.

(a) Data are for 12 months ended 31 October.
(b) Calculated on unrounded RSE estimates.


12 As indicated in the table above, the estimates of movement are subject to significant sampling error and caution should be used when making inferences about change. For example, the estimate of movement for passenger vehicles is an increase of 13,445 million kilometres and the standard error is 7,066 million kilometres, which means there are 19 chances in 20 that the true movement is between a decrease of 687 million kilometres and an increase of 27,577 million kilometres (a range of two standard errors above and below the movement estimate).


NON-SAMPLING ERROR

13 Non-sampling error covers the range of errors that are not caused by sampling and can occur in any statistical collection whether it is based on full enumeration or a sample. For example, non-sampling error can occur because of non-response to the statistical collection, errors or omissions in reporting, definition or classification difficulties, errors in transcribing and processing data and under-coverage of the frame from which the sample was selected. If these errors are systematic (not random) then the survey results will be distorted in one direction and therefore will be unrepresentative of the target population. Systematic errors result in bias.


Response and non-response

14 An important factor that affects non-sampling error is the response rate achieved. The ABS makes all reasonable efforts to maximise response rates. Where appropriate, mail reminders and telephone follow-up are used to attempt to contact non-responding vehicle owners. Usable responses were received from 75% of all of the selections for 2014, comprised of 71% from registered vehicles and 4% from unregistered vehicles, out of scope and duplicates.

15 After removing those vehicles that had been found to be deregistered or out of scope, the response rate for the 2014 SMVU was 73%.

16 Response rates for each state and territory, and for each vehicle type, are shown in the following tables:

17 For the SMVU, it is assumed that the characteristics of non-responding vehicles are the same as for like responding vehicles. Non-response has the potential to cause non-response bias, which occurs if the usage patterns of the non-responding vehicles differ from those of the responding vehicles. For example, the lowest response rate achieved by vehicle type was for rigid trucks (71%). This could result in the estimates for rigid trucks being of a lower quality than other vehicle types.


Frame quality

18 The scope of the survey comprises all vehicles that were registered with a motor vehicle authority for road use at some stage during the 12 months ended 31 October 2014 (excluding caravans, trailers, tractors, plant and equipment, defence services vehicles, diplomatic or consular-plated vehicles and vintage or veteran registered vehicles). A population or survey frame of 17.2 million vehicles was identified on 31 January 2013 using information obtained from the state and territory motor vehicle registration authorities, as part of the annual ABS Motor Vehicle Census (MVC) (cat. no. 9309.0). From this frame a stratified sample of 16,000 vehicles was selected for reporting on vehicle use.

19 In 2014, the effects of duplicate vehicle registrations, vehicle de-registrations prior to frame extract, and out-of-scope vehicles on the frame was estimated to be approximately 0.3% of the total frame. This


indicates the frame was reliable in terms of providing an accurate number of registered vehicles in Australia.

20 Vehicle classification anomalies arise when respondents indicate an alteration has been made to the vehicle body, resulting in a different vehicle type to that recorded on the frame. These changes can happen during the time-lag between finalising the frame and collection of SMVU data (between 9 and 21 months). Vehicle classification anomalies can also result from data supplied by state and territory vehicle registration authorities. An assessment of vehicle classification anomalies from 2014 data shows that while there was no bias towards specific states or territories, there were marked discrepancies for some vehicle types. For vehicles on the frame that were listed as non-freight carrying trucks, 23.7% were found to be other vehicle types and 14.2% of vehicles listed as buses were found to be other vehicle types. This issue was not significant for other vehicle types on the frame.


Imputation

21 Imputation is the process whereby a value is generated for missing data items, based on the responses for similar vehicles which were operating for the reference period. This is called partial imputation. As for previous surveys, the need for imputation of unanswered items on the returned questionnaires remained quite high.

22 Additional imputation is needed due to questionnaire non-response and is called full imputation. The tables below show the percentage contribution to the estimates from both partial and full imputation.

SURVEY PROCEDURES

23 The survey is comprised of three independent samples, with a different one used for each four month period in the overall 12 month survey period. Estimates from each of these samples are aggregated and adjusted for new motor vehicles and re-registrations of vehicles to produce an annual estimate.


Coherent Estimates

24 The 2014 SMVU was run with an additional road freight component, published in Road Freight Movements, Australia (cat. no. 9223.0). The SMVU 2014 and the road freight component were designed together to provide coherent estimates at the state of registration by vehicle type level for total distance travelled, tonne-kilometres and total tonnes.


Adjustments

25 The SMVU aims to measure the use of all vehicles registered during the reference year. Because selections are taken from vehicles registered some time before the beginning of each collection period, adjustments are made to account for the change in size of the registered motor vehicle fleet since the population frame was created. For the 2014 SMVU, the frame was created on 31 January 2013. These adjustments involved two categories:
  • re-registrations - older vehicles that are returning to the registered vehicle fleet after a period of de-registration, and
  • new motor vehicles - vehicles which have not been previously registered.

(a) Estimates for 2014 were produced using a different method than in 2006, 2007, 2010, 2012. The contribution of adjustments for re-registrations for 2014 is not comparable with other years.
(b) Data for 2006, 2007, 2010, 2014 are for 12 months ended 31 October. Data for 2012 are for 12 months ended 30 June.


26 These activities occur continuously and the adjustments are made to account for the registrations that are estimated to have been added to or removed from the registered vehicle fleet between the population frame date and the end of the reference period. The adjustment process also accounts for de-registrations. This means it is possible for the re-registration factor to be negative.

Pre-advice methodology

27 The quality of survey responses is improved by employing a pre-advice methodology. This involves vehicle owners receiving early advice about their inclusion in the survey and encourages a higher degree of record keeping. In addition, the reporting of odometer readings taken at the start and end of the survey periods (approximately four months apart) provide reliable estimates of total distance travelled without a recall bias.


Nil use

28 Some providers may report nil use for the 4 month reference period in which they were selected. Nil use vehicles are registered vehicles that report no travel during that specific reference period. Nil use vehicles are included in the survey as their reported nil use is representative of other vehicles in the population. Vehicles may have nil use due to factors such as seasonal usage, mechanical faults or economic conditions. Where a provider gives a nil use response, a follow-up phone call is used to check the veracity of the response.

DISTRIBUTIONS

29 The following tables provide values for total kilometres travelled and total tonne-kilometres travelled for selected percentiles. These percentiles have been calculated from all values reported in each third of the reference period. Percentiles provide some indication of the distribution of vehicle use across the survey population. For example, one-fifth of New South Wales passenger vehicles reported a distance travelled of 1,623 kilometres or less for the third they were selected in the survey. Note that the minimum value for every combination of state/territory by type of vehicle for both tables is zero.

30 Users should contact the ABS if they have any queries on the quality and reliability of estimates for particular purposes.
