HKU POP SITE releases the latest popularity figures of CE Donald Tsang and the HKSAR GovernmentBack

The Public Opinion Programme at the University of Hong Kong interviewed 1,023 Hong Kong people between 20 and 22 May by means of a random telephone survey conducted by real interviewers. The survey finds that since the end of February and early March last year, the popularity figures of CE Donald Tsang have been very stable. His approval rate fluctuated between 63% and 64%, while his support rating fluctuated between 64 and 66 marks. They are all narrow fluctuations. As for the popularity of the SAR Government, since February last year, people's satisfaction rate has basically fluctuated around 50%. There were some bigger ups and downs between October and December last year, but they soon settled after three months. In other words, the recent Olympic torch relay and Sichuan earthquake did not have much effect on the popularity of the CE and the SAR Government. The sampling error of all percentages is below +/-2 to 3 percentage points at 95% confidence level, while the sampling error of rating figure is below +/-1.2 marks. The response rate of the survey is 67%.

Points to note:

* The address of the "HKU POP SITE" is http://hkupop.pori.hk, journalists can check out the details of the survey there.
* The sample size of this survey is 1,023 successful interviews, not 1,023 x 67.1% response rate. In the past, many media made this mistake.
* The maximum sampling error of all percentages is below +/-2 to 3 percentage points at 95% confidence level, while the sampling error of rating figure is below +/-1.2 marks. "95% confidence level" means that if we were to repeat a certain survey 100 times, using the same questions each time but with different random samples, we would expect 95 times getting a figure within the error margins specified. When quoting these figures, journalists can state "sampling error below +/-3% at 95% confidence level for percentage figures, and +/-1.2 for rating figure".
* When quoting percentages of this survey, journalists should refrain from reporting decimal places, but when quoting the rating figures, one decimal place can be used, in order to match the precision level of the figures.
* The data of this survey is collected by means of random telephone interviews conducted by real interviewers, not by any interactive voice system (IVS). If a research organization uses "computerized random telephone survey" to camouflage its IVS operation, it should be considered unprofessional.

POP today releases on schedule via the "POP SITE" the latest popularity figures of CE Donald Tsang and the HKSAR Government. As a general practice, all figures have been weighted according to provisional figures obtained from the Census and Statistics Department regarding the gender-age distribution of the Hong Kong population in 2007 year-end. Herewith the contact information for the latest survey:

The latest survey conducted in mid-May showed that, CE Donald Tsang scored 66.0 marks, and 63% supported him as the Chief Executive. Regarding people's appraisal of the overall performance of the HKSAR Government, the latest figures revealed that 50% were satisfied, whereas 11% were dissatisfied.

In January 2007, POP opened a feature page called "Opinion Daily" at the "POP Site", to record significant events and selected polling figures on a day-to-day basis. Our purpose is to provide readers with accurate information so that they can judge by themselves the reasons for the ups and downs of different opinion figures. When "Opinion Daily" began to operate on January 17, 2007, it only contained significant events and popularity figures of the Chief Executive over the past few months. As of today, it contains a chronology of events starting from May 1, 2006, and many poll figures registered since January 1, 2006. Readers can now check on the results of 9 different polling items compiled by POP, including the popularity of the Chief Executive, the HKSAR government, and the Secretaries of Departments under the accountability system. In near future, the content of "Opinion Daily" will continue to expand, in order to promote the science of opinion polling.

In July 2007, POP collaborated with Wisers Information Limited whereby Wisers supplies to POP since July 24 each day a record of significant events of that day, according to the research method designed by POP. These daily entries would be uploaded to the "Opinion Daily" feature page as soon as they are verified by POP, in order to provide readers with swifter and more accurate information.

In August 2007, POP began to include in its regular press releases a list of significant events which happened in between two surveys, so that readers can make their own judgment on whether these events have any effect on the ups and downs of the polling figures. This press release is no exception.

For the polling items covered in this press release, the previous survey of some items was conducted from April 16 to 18, 2008 while this survey was conducted from May 20 to 22, 2008. In between these two surveys, herewith the significant events selected from counting newspaper headlines and commentaries on a daily basis and covered by at least 25% of the local newspaper articles. Readers can make their own judgment if these significant events have any impacts to different polling figures.

Robert Ting-Yiu Chung, Director of Public Opinion Programme, observed, "Since the end of February and early March last year, the popularity figures of CE Donald Tsang have been very stable. His approval rate fluctuated between 63% and 64%, while his support rating fluctuated between 64 and 66 marks. They are all narrow fluctuations. As for the popularity of the SAR Government, since February last year, people's satisfaction rate has basically fluctuated around 50%. There were some bigger ups and downs between October and December last year, but they soon settled after three months. In other words, the recent Olympic torch relay and Sichuan earthquake did not have much effect on the popularity of the CE and the SAR Government. As for the effect of other events, we will leave it to our readers to form their own judgment using the detailed records displayed in our "Opinion Daily"."

POP's normal practice is to release the results of our regular surveys every Tuesday afternoon via our POP Site, except during public holidays, each time with a forecast of the items to be released in the next 7 days. According to schedule, our next release of regular survey findings will be May 29, 2008, Thursday, between 1pm and 2pm, when the latest ratings of the top 10 political groups will be released. Then on June 3, 2008, Tuesday, between 1pm and 2pm, POP will release the results of latest annual June Fourth survey.

It is our general practice to answer all questions on the research design of the surveys published in the POP Site as soon as we receive them, but we will not further comment on the findings. We welcome questions for follow-up purpose, please email them to us at <[email protected]>. We will keep such an arrangement under constant review, suggestions most welcome. Please note that everything carried in the POP Site does not represent the stand of the University of Hong Kong. Dr Robert Ting-Yiu Chung, Director of POP, is responsible for everything posted herewith, except for column articles which represent the stand of their authors.

Since January 2006, we have included in our regular press releases a small educational section for the purpose of sharing our research experience with the readers and the general public, and the subject of our education section today is "About HKUPOP".

Again on mapping people's trust and satisfaction of different governments

One important aspect of opinion polling around the world is to monitor people's trust and satisfaction of the government. Shortly after HKUPOP was established, we started to conduct surveys on these aspects. Regarding the development of these surveys, we have explained it separately in our press releases of August 22, November 28, December 14 and 27, 2006, April 3, July 3, September 25, October 30, November 27 and December 28, 2007, January 22, March 25 as well as April 22, 2008. Today, we post it again in order to give readers a complete picture of such developments.

(1) Mapping people's trust in different governments

• Due to Hong Kong's very special political status, before the handover in 1997, our survey covered people's trust in the British Hong Kong, British, Chinese, and Taiwan Governments. After the handover, the survey method remained unchanged, but the term British Hong Kong Government was substituted by HKSAR Government, and Chinese Government was substituted by Central Government, while our survey on people's trust in the British Government stopped.



• Our surveys began in December 1992, the wordings used in the questionnaire are "On the whole, do you trust such and such government?". Surveys were conducted once every month, until October 1997 when it was changed to once every two months. It has remained unchanged since then.

(2) Mapping people's satisfaction with the government

• In December 1992, we started to survey people's trust in the British Hong Kong, British, Chinese, and Taiwan Governments. These surveys continued after the handover, but we expanded their scope by introducing people's satisfaction with the HKSAR Government. We take measurements as frequently as we could, using our limited resources. Besides people's general satisfaction with the HKSAR Government, our survey also includes indicators on the government's performance in maintaining economic prosperity, improving people's livelihood, pace of democratic development, and so on.



• Our surveys on people's satisfaction with the HKSAR Government in general began in July 1997. Since then, it has been conducted once every month. The wordings used in the questionnaire are "Are you satisfied with the overall performance of the HKSAR Government?".



• Also from July 1997, we began to survey people's satisfaction with the government's performance in five policy areas using the following questions: "Are you satisfied with the performance of the HKSAR Government in maintaining economic prosperity / improving people's livelihood / developing democracy / protecting human rights and freedom / handling of its relation with the Central Government?" The frequency of these sub-indicator surveys, however, was gradually thinned down from once every month at the beginning, to once every two months between July 2000 and May 2003, and then to once every three months since July 2003, in order to match the changing social conditions.

Before May 2000, the sample size of our regular surveys was set at slightly over 500, we increased it to at least 1,000 after that. The above surveys are no exceptions. The findings of these surveys are now published regularly on-line at our HKU POP Site, while all previous findings published via our newsletter POP Express have also been uploaded on-line in various formats.
