INTRODUCTION

The Survey of Tourist Accommodation (STA) frame is based on an electronic file supplied each quarter by AAA Tourism. Since December 2002, AAA Tourism have been more active in maintaining their listing of accommodation establishments on this electronic file.

This active maintenance has resulted in a large number of hotels, motels and guest houses and serviced apartments being identified for the first time in both the March quarter 2003 and the June quarter 2003. While these establishments were identified in these quarters, they actually commenced operations prior to these time periods. The number of establishments identified in the March quarter was 115 and in the June quarter 17 (132 in total).

These additional 132 establishments were added to the STA frame in the June quarter 2003. The addition of these 132 establishments added $31.9 million (2.7%) to the total takings from accommodation for the June quarter, 285,689 room nights occupied (2.8%) and 5,918 guest rooms available (2.9%).

The most significant impact was in serviced apartments, which added $18.6 million to total takings. This is 1.6% of the total accommodation takings for the June quarter 2003 and 7.3% of takings from serviced apartments. Serviced apartments also contributed 164,274 room nights occupied. This was 1.6% of the total room nights occupied for the June quarter 2003 and 7.8% of room nights occupied in serviced apartments.

The addition of the 132 tourism establishments resulted in a break in time series between the March and June quarters 2003. The impact of the break in time series is explained below.

THE IMPACT OF THE BREAK

The extent of the impact varies by geographic region. As can be seen in the table below the major additions occur in New South Wales, Victoria and Queensland and within those states/territories for serviced apartments.

The effect of the break in series on key data items for the separate activity types of hotels, motels and guest houses and serviced apartments is shown in the following tables. Some information is suppressed due to confidentiality.

Table 2 shows that 1,058 additional guest rooms were added to hotels in Australia in June quarter 2003. This was 1.4% of the 78,089 hotel rooms in Australia. The most significant addition was for serviced apartments with 3,262 guest rooms added, which was 8.3% of total serviced apartments rooms available.

Table 3 shows that New South Wales had $9.4 million added to total takings for hotels, motels and guest houses and serviced apartments combined. This was 2.5% of the total takings for New South Wales. Overall, the additional 132 establishments added $31.9 million (2.7%) to total takings from accommodation for Australia.

Table 5 in the attachment at the end of this Appendix shows how the 132 establishments which were added to June quarter 2003 were distributed at the Tourism Region level. Also supplied is the AAA Tourism count of rooms available.

Where releasable, the contribution of the 132 establishments to key data items at the Tourism Region level is shown in Tables 6 to 12 in the attachment at the end of this Appendix. These tables present factors which can be used to take into account the break in series.

Some factors are suppressed due to confidentiality. In these cases the number of rooms available information shown in Table 5 will provide an indication of the significance of the change.

Almost all SLAs have had less than three establishments added, therefore most factors at this level are confidential. Releasable factors for six SLAs are contained in Table 13 in the attachment at the end of this Appendix. Factors for these SLAs are only available for hotels, motels and guest houses and serviced apartments combined.

DERIVED ITEMS

A number of STA data items are calculated by the ABS after data has been collected from providers. These items are derived by dividing one collected data item into another. The data items are:
  • Bed occupancy rate
  • Room occupancy rate
  • Average takings per room night occupied
  • Average takings per room night available
  • Average length of stay

Both the numerator and denominator used to calculate these items have been affected by the additional 132 establishments to a similar extent. Therefore the addition of the 132 establishments has a minimal effect on the calculation of these data items. Thus a break in series is not likely to have occurred for the derived data items.

PERCENTAGE CHANGES

The addition of the 132 establishments increased the level of the series from the June quarter 2003. When calculating percentage changes over time care needs to be taken to ensure the effect of the break in series is taken into account.

Tables 6 to 14 contain factors for use when calculating percentage changes. These factors were calculated by dividing June quarter 2003 figures including the 132 additional establishments, by the June quarter 2003 figures excluding the additional establishments. These factors adjust the level of the series prior to June quarter 2003 to take account of the missing 132 establishments.

Care should be taken when calculating percentage changes as not all 132 additional establishments may have been open in the quarter to which the factor is being applied. By using the factor to add the 132 establishments to the data, the estimate may be increased to a figure which is more than it should be. This will result in the percentage change between that quarter and June quarter 2003 being under-estimated.

Users should contact the Transport and Tourism Business Statistics Centre for further information on the contribution of the additional establishments to earlier quarters.

The method for calculating the percentage change is shown by the example below. Takings from accommodation data can be found in Tables 1 and 2 of this publication. Factors for original data can be found in Table 12 in the attachment at the end of this Appendix. Seasonally adjusted and trend factors are contained in Table 14 in the attachment at the end of this Appendix.

Original data

To calculate the percentage change between December quarter 2002 and December quarter 2003 for takings from accommodation the following steps are undertaken:

    Step 1:
    Multiply the December quarter 2002 figure by the appropriate factor to obtain an adjusted December quarter 2002 figure
    $1,314,053 x 1.02824 = $1,351,162

    Step 2:
    Calculate the percentage change in the usual manner except in this case use the adjusted December quarter 2002 figure
    ($1,499,344/$1,351,162 - 1 ) x 100 = 11.0%

This same methodology applies for all calculations of percentage changes that cross the break in series (ie June quarter 2003). Factors are not needed when calculating percentage changes before the break in series.

Seasonally Adjusted and Trend Estimates

Seasonally adjusted and trend estimates are subject to the same break in series. Care should be taken when calculating percentage changes to ensure the effect of the break in series is taken into account. The same methodology as described above should be applied to these data to calculate percentage changes, although a different factor should be used. These factors are contained in Table 14 in the attachment at the end of this Appendix.

Note that seasonally adjusted and trend estimates are only produced for the data items of takings from accommodation and room occupancy rate. As the break in series does not impact on derived data items, the factors in Table 14 need only be applied to takings from accommodation.

Monthly data

The additional 132 establishments have been added into each month of the June quarter 2003 (ie April, May, June). Therefore the break in series has occurred between the months of March and April 2003. When calculating percentage changes, the appropriate quarterly factor should be used to adjust monthly data in respect of the break in series.

Users should contact the Transport and Tourism Business Statistics Centre if they have any queries on the break in series.

TABLES

Table 5 shows the geographic distribution of the additional 132 establishments. Factors for use when calculating percentage changes are contained in Tables 6 to 14.
