Latest Figures
 

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. All the 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 at the end of 2006. Herewith the contact information for the latest survey:


 Date of survey  Overall sample size   Response rate   Sampling error of percentages* 
 3-6/7/2007   1,015   63.4%   +/- 3% 
* Calculated at 95% confidence level using full sample size. "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. Questions using only sub-samples would have bigger sample error. Sampling errors of ratings are calculated according to the distribution of the scores collected.
 

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:

 
Sample size
(total sample or sub-sample) 
 Sampling error for percentages*(maximum value)   Sample size
(total sample or sub-sample) 
 Sampling error for percentages*(maximum value)
 1,300    +/- 2.8 %   1,350    +/- 2.7 % 
 1,200    +/- 2.9 %   1,250    +/- 2.8 % 
 1,100    +/- 3.0 %   1,150    +/- 3.0 % 
 1,000    +/- 3.2 %   1,050    +/- 3.1 % 
 900    +/- 3.3 %   950    +/- 3.2 % 
 800    +/- 3.5 %   850    +/- 3.4 % 
 700    +/- 3.8 %   750    +/- 3.7 % 
 600    +/- 4.1 %   650    +/- 3.9 % 
 500    +/- 4.5 %   550    +/- 4.3 % 
 400    +/- 5.0 %   450    +/- 4.7 % 
* Based on 95% confidence interval.
 

"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 +/-1.2, sampling error of percentages not more than +/-3% at 95% confidence level" when quoting the above figures.

* 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.
^ Henry Tang has been appointed as CS from 1 July 2007 onwards. Prior to that he was the FS.

Commentary

Robert Ting-Yiu Chung, Director of Public Opinion Programme, observed, "According to our survey conducted after Donald Tsang's cabinet took office, but before the government published its Green Paper on Constitutional Development, both the support rating and support rate of CE Donald Tsang have not changed much, compared to mid-June. As for the three Secretaries of Departments, those who supported Henry Tang to become Chief Secretary has dropped 18 percentage points compared to those who supported him as Financial Secretary in mid-June, while those who supported Wong Yan-lung as Secretary of Justice has increased by 7 percentage points. As for the Directors of Bureaux, almost all of those who have been reappointed to their old posts, or re-deployed to some new posts, have gained in popularity, especially for Michael Suen. As expected, the recognition rates of the newly appointed principal officials are generally low. This may not post any problem for the time being, but if the situation lingers on for more than 6 months, then the officials concerned should really think about it. According to the benchmarks developed by POP for mapping the popularity of these officials, Ambrose Lee, Wong Yan-lung and Donald Tsang can be labeled as 'ideal', since their approval rates are more than 66%. Henry Tang, Matthew Cheung and York Chow can be labeled as 'successful' with support rates exceeding 50%. The combined support and disapproval rates of Ceajer Chan, Tsang Tak-sing, John Tsang*, Eva Cheng and Edward Yau do not reach 50%, so their performance can be labeled as 'inconspicuous'. The performances of all other officials range between 'successful' and 'depressing' and can be labeled as 'mediocre'. No official falls under the categories of 'depressing' or 'disastrous. POP will continue to explain the concept of these benchmarks, in order to facilitate further discussions on how to make these principal officials more accountable to the general public."

* John Tsang was accidentally omitted from the original draft of the commentary.

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, March 13 as well as June 12, 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 to June 2007, 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 to June 2007, the survey was conducted once every two months. In July 2007, with the beginning of CE's new term of office and the appointment of new principal officials, the frequency of support rate survey of the Directors of Bureaux was increased to once every month, while the frequency of rating survey was reduced to once every three months. Moreover, although all survey results are uploaded onto the POP Site in detail, POP no longer analyze the result of rating surveys. This is to better match the evolvement of the accountability system as well as the pace of democratic development.

  • 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.
