SEASONALLY ADJUSTED AND TREND ESTIMATES


INTRODUCTION

Seasonally adjusted and trend estimates add to the understanding of overseas arrivals and departures (OAD) statistics. Seasonally adjusted estimates allow users to analyse short-term movements including irregular impacts on the series, while trend estimates provide a better method to analyse and monitor the underlying direction of the short-term movement series. In most cases the trend series is the best source of information on the long-term direction of these statistics.



SHORT-TERM VISITOR ARRIVALS

Selected source countries

The graph for the United States of America shows the large increase in the seasonally adjusted series for short-term visitor arrivals in September 2000, during the Olympic Games in Sydney. For New Zealand the graph shows small fluctuations after strong increases which commenced in early 2003. The graph for Japan shows the significant impact of Severe Acute Respiratory Syndrome (SARS) on the seasonally adjusted arrivals series in mid-2003.

SHORT-TERM RESIDENT DEPARTURES

Selected destinations

For residents departing to the United States of America the graph illustrates the effect of the 11 September 2001 terrorist attacks in that country on short-term departures of Australian residents to the United States of America. The graph for New Zealand indicates that the trend series for departures of Australian residents continues to increase after a plateau since mid-2004. For Indonesia the graph shows the impact of the 12 October 2002 Bali bombing and the reduced level of travel experienced in the next twelve months. The effect of the 1 October 2005 Bali bombing is also evident and another break in the trend series was introduced.
