Latest Figures
 

POP SITE today releases on schedule 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   Maximum Sampling error of percentages* 
 1-6/3/2007   1,008   60.6%   +/- 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:

* 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.

Meanwhile, the corresponding ratings of CS Rafael Hui Si-yan, FS Henry Tang Ying-yen and SJ Wong Yan-lung were 56.4, 65.6 and 65.5 marks, and 33%, 74% and 62% would vote for their reappointment correspondingly. As for the Directors of Bureaux, results revealed that the 1st rank fell to Secretary for Security Ambrose Lee Siu-kwong, attaining 62.9 marks. Secretary for Economic Development and Labour Stephen Ip followed behind in the 2nd rank, scoring 59.6 marks. Secretary for the Environment, Transport and Works Sarah Liao and Secretary for the Civil Service Denise Yue captured the 3rd and 4th place with 58.6 and 57.3 marks. The 5th to 7th ranks went to Secretary for Health, Welfare and Food York Chow, Secretary for Financial Services and the Treasury Frederick Ma and Secretary for Commerce, Industry and Technology Joseph Wong, scoring 56.7, 54.2 and 54.0 marks respectively. Secretary for Home Affairs Patrick Ho, Secretary for Housing, Planning and Lands Michael Suen and Secretary for Constitutional Affairs Stephen Lam occupied the 8th to 10th ranks, scoring 51.8, 51.1 and 51.0 marks in corresponding order. Secretary for Education and Manpower Arthur Li occupied the 11th place, with a popularity rating of 48.4 marks.


Commentary

Robert Ting-Yiu Chung, Director of Public Opinion Programme, observed, "Due to people's positive reception of the Budget Speech this year, the popularity of the CE and almost all principal officials has increased. FS Henry Tang registered the sharpest rises, as his support rating surged 4.8 marks after the Budget Speech, while his support rate climbed 11 percentage points, both figures being his record high. As for other officials, compared to two months ago, Secretary for Constitutional Affairs Stephen Lam, Secretary for Health, Welfare and Food York Chow, and Secretary for Commerce, Industry and Technology Joseph Wong registered significant increases in support ratings. Secretary for Education and Manpower Arthur Li, however, due to the Hong Kong Institute of Education Incident, has dropped significantly to become the most disliked official. It should be noted, however, the popularity figures of the CE in this survey are conceptually different from those obtained in our CE election surveys, which are more concerned with the suitability and relative strength of different candidates. Since CE Donald Tsang did not step down from his post to take part in the election, as what he did two years ago, we will continue to conduct two different types of surveys in parallel, in order to measure Donald Tsang's popularity as an incumbent CE and as a CE candidate."

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, 2007 as well as February 8, 2007. Today, we release an updated version with some editing, 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 are asked in different surveys separately.

  • 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.
