The Public Opinion Programme (POP) at the University of Hong Kong today releases on schedule via the "HKU POP SITE" (http://hkupop.pori.hk) the latest popularity figures of CE Donald Tsang and Principal Officials under the accountability system. 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 2006 year-end. Herewith the contact information for the latest survey: 

As different questions involve different sub-samples, the sample errors will vary accordingly. The table below briefly shows the relationship between sample size and maximum sampling errors for the readers to capture the corresponding changes:

"Maximum sampling errors" occur when survey figures are close to 50%. If the figures are close to 0% or 100%, the sampling error will diminish accordingly. The sampling errors of ratings, however, will depend on the distribution of the raw figures. Since January 2007, POP lists out the sampling errors of all survey figures in detail and explain them in due course. Recent popularity figures of Donald Tsang are summarized as follows:

* 「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. Media can state 「sampling error of ratings +/-1.0, sampling error of percentages not more than +/-3% at 95% confidence level」 when quoting the above figures.

Figures on the latest popularity ratings of the three Secretaries of Departments under the accountability system are summarized below:

* The frequency of this series of questions is different for different questions, and also different from that of CE popularity ratings. Comparisons, if made, should be synchronized using the same intervals.
** "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. Media can state 「sampling error of various ratings not more than +/-1.2, sampling error of percentages not more than +/-3% at 95% confidence level」 when quoting the above figures.
# This series of questions only uses sub-samples of our Budget instant survey, the sample size for each question also varies. Regarding the change of Henry Tang's popularity figures, one can compare them per poll, or with other officials' figures after synchronizing them to the same cycle.

Figures on the latest popularity ratings of Directors of Bureaux under the accountability system are summarized below:

* Starting from 2006, these questions only uses sub-samples of the tracking surveys concerned, the sample size for each question also varies.
** "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. Media can state "sampling error of ratings not more than +/-2.0 at 95% confidence level" when quoting the above figures.
^ This series of questions was conducted once every two months, different from the frequency of hypothetical support ratings. Comparisons, if made, should be synchronized using the same cycle.

The latest survey showed that, CE Donald Tsang scored 67.3 marks, and 74% supported him as the Chief Executive. Meanwhile, the corresponding ratings of CS Rafael Hui Si-yan, FS Henry Tang Ying-yen and SJ Wong Yan-lung were 57.7, 64.6 and 66.8 marks, and 35%, 68% and 65% would vote for their reappointment correspondingly.

Commentary

Robert Ting-Yiu Chung, Director of Public Opinion Programme, observed, "According to our latest survey, the support rating of CE Donald Tsang has dropped compared to that of mid-April, but his support rate has increased a bit. Overall, CE's popularity has remained stable. According to our records in the 'Opinion Daily' section of our POP Site, major events which occurred in the interim period include the arrival of the two pandas, CE's announcement of government restructuring, increase in visitors during the 'Golden Week', and the grading of Queen's Pier as a grade one historic building. We leave it open for readers to interpret whether the events have affected the CE's popularity. As for the Secretaries of Departments, the support ratings and support rates of all three Secretaries have not changed much compared to one month ago. However, for the Directors of Bureaux, compared to two months ago, Arthur Li's rating has dropped significantly, while the ratings of all others have fluctuated within sampling errors. Arthur Li is now the least popular principal official with just 46 marks."

About HKUPOP

Popularity surveys of CE and principal officials

In advanced democratic countries, the popularity of top leaders and principal officials is the crux of all opinion polls. Shortly after HKUPOP was established, we started to conduct surveys on these aspects. We have explained the development of these surveys in our press releases of October 31, 2006, January 16 and 31, February 8 as well as March 13, 2007. Today, we post it again, so that readers can have a more comprehensive picture of such development. 

(1) Development of CE's popularity survey

• From its establishment to the handover of Hong Kong, POP has continually conducted surveys to measure the popularity rating of Governor Chris Patten. After the handover when Tung Chee-hwa became the first Chief Executive in 1997, we began our popularity survey of CE Tung Chee-hwa. After Tung resigned and Donald Tsang succeeded, POP has begun to measure Tsang's popularity. The frequency of our surveys was at least once every month during the Patten era. It was then increased to three times per month when Tung became CE, until the end of 1997. From January 1998 onwards, it was reduced to twice every month.
  
  

• The question wordings used in "popularity of Governor or CE" survey are: "Please use a scale of 0-100 to rate your extent of support to the Governor/ the Chief Executive XXX, with 0 indicating absolutely not supportive, 100 indicating absolutely supportive and 50 indicating half-half. How would you rate the Chief Executive XXX?" and "If a general election of the Chief Executive were to be held tomorrow, and you had the right to vote, would you vote for XXX?".
  
  

• Before April 2000, the sample size of our regular surveys was set at slightly over 500. After that, it was increased to at least 1,000.

(2) Development of CE's popularity (performance) survey

• The frequency of our surveys was once every two months since August 2002. From February 2004 onwards, it was reduced to once every six months.
  
  

• The question wordings used in "CE popularity (performance)" survey are: "Do you think XXX is doing a good or bad job as CE?".
  
  

• Regarding the sample size, ever since the beginning, the sample size of surveys has been set at slightly over 1,000.

(3) Development of the survey for Secretaries of Departments:

• For the rating survey of the Secretaries of Departments, in between January to November 2001, the survey was conducted at an irregular basis. From January 2002 onwards, the survey is conducted once every month. For the support rates of the Secretaries based on people's hypothetical vote of confidence, it was surveyed once every three months from September 2002 to December 2003. Then it was changed to once every two months from February 2004 to December 2005. From January 2006 onwards, the survey is conducted once every month.
  
  

• The wordings used in the questionnaire are: "Please use a scale of 0-100 to rate your extent of support to Chief Secretary for Administration XXX/Financial Secretary YYY/Secretary for Justice ZZZ, with 0 indicating absolutely not supportive, 100 indicating supportive and 50 indicating half-half. How would you rate XXX/YYY/ZZZ?". For the support rates of Secretaries, the wordings are "If you had the right to vote on the reappointment or dismissal of XXX/YYY/ZZZ as the Chief Secretary for Administration/Financial Secretary/Secretary for Justice tomorrow, how would you vote?"
  
  

• Regarding the sample size, ever since the beginning, the sample size of surveys has been set at slightly over 1,000. 

(4) Development of the survey for Directors of Bureaux:

• For the rating survey of the Directors of Bureaux, in between June 2002 to December 2005, the frequency was once every month. From January 2006 onwards, the survey is conducted once every two months. For the support rates of Directors of Bureaux, the frequency was once every three months from September 2002 to December 2003. Then from February 2004 onwards, the survey is conducted once every two months.
  
  

• Similar to the popularity survey of the Secretaries of Departments, that of the Directors of Bureaux also includes the questions of rating and hypothetical voting. The wordings used in the questionnaire are: "Please use a scale of 0-100 to rate your extent of support to XXX, with 0 indicating absolutely not supportive, 100 indicating supportive and 50 indicating half-half. How would you rate XXX?" and "If you had the right to vote on the reappointment or dismissal of XXX as YYYYYY tomorrow, how would you vote?" However, the two questions may not be asked in the same survey.
  
  

• Regarding the sample size, from the beginning to December 2005, the sample size of the surveys was set at slightly over 1,000. However, from 2006 onwards, this series of questions only uses sub-samples of the tracking surveys concerned, and the sample size for each question also varies.

All the findings from our surveys on "popularity of principal officials" have been released online through our HKU POP Site.
