4 Occasionally situations occur that necessitate breaks being applied to the trend series. These breaks are necessary because of a change in the underlying level of the series. While the breaks apply to an individual country (e.g. Indonesia) a consequence is that breaks are also applied to the regional total series (e.g. Total South-East Asia) and the total series. Breaks currently included in the trend series are as follows:
      • October 2002; STRD - Indonesia, Total South-East Asia and Total
          • Effect on trend and reason - Decrease in STRD movements; Bali Bombing of 12 October 2002
      • December 2003; STRD - Indonesia, Total South-East Asia and Total
          • Effect on trend and reason - Increase in STRD movements; Return to levels experienced prior to the Bali Bombing of 12 October 2002
      • October 2005; STRD - Indonesia, Total South-East Asia and Total
          • Effect on trend and reason - Decrease in STRD movements; Bali Bombing of 1 October 2005
      • December 2006; STRD - Indonesia, Total South-East Asia and Total
          • Effect on trend and reason - Increase in STRD movements; Return to levels closer to, but still lower than, those experienced prior to the Bali Bombing of 1 October 2005.
      • April 2009; STRD - All countries, Total region and Total in the following regions: Oceania and Antarctica, North-West Europe, South-East Asia, North-East Asia, Southern and Central Asia, Americas and Sub-Saharan Africa
          • Effect on trend and reason - Increase in STRD movements; Global Financial Crisis (GFC) and initiatives introduced to combat the GFC (e.g. Australian Government stimulus packages of October 2008 and February 2009), cut-price air fares and travel packages, and the high Australian dollar).
              • Comments - Breaks in series were clearly observed for Indonesia, Malaysia, New Zealand and the United Kingdom. Further smaller breaks were applied to the remaining specified country series.
      • July 2009; STRD - Fiji, Total Oceania and Antarctica
          • Effect on trend and reason - Increase in STRD movements; Increased flights, cut-price fares and the high Australian dollar.
              • Comments - The break in series for Fiji will be illustrated in specific commentary, tables and graphs on Fiji and Total Oceania and Antarctica. However, although Fiji is included in the total series its impact is minimal and not observable amongst other volatility during this time. Therefore, it has not been illustrated in commentary, tables and graphs at this level.
      • February 2011; STRD - Egypt, Total North Africa and the Middle East
          • Effect on trend and reason - Decrease in STRD movements; Ongoing political instability in Egypt.
              • Comments - The break in series for Egypt will be illustrated in specific commentary, tables and graphs on Egypt and Total North Africa and the Middle East. However, although Egypt is included in the total series its impact is minimal and not observable amongst other volatility during this time. Therefore, it has not been illustrated in commentary, tables and graphs at this level.
      • March 2011; STRD - Japan, Total North East Asia
          • Effect on trend and reason - Decrease in STRD movements; Major earthquake and tsunami on 11 March 2011 in Japan and subsequent nuclear radiation exposure incidents.
              • Comments - The break in series for Japan will be illustrated in specific commentary, tables and graphs on Japan and Total North East Asia. However, although Japan is included in the total series its impact is minimal and not observable amongst other volatility during this time. Therefore, it has not been illustrated in commentary, tables and graphs at this level.
