| Detailed Findings (Rating of Chief Executive Leung Chun-ying) | Detailed Findings (Popularity of Principal Officials) |

Special Announcement

To facilitate academic study and rational discussion, The Public Opinion Programme (POP) of The University of Hong Kong has already released for public examination some time ago via the “HKU POP SITE” (http://hkupop.pori.hk) the raw data of all 81 regular rating surveys of CE CY Leung, as well as the 181 regular rating surveys of former CE Donald Tsang and 239 regular rating surveys of former CE CH Tung, along with related demographics of respondents. POP today releases the raw data of the latest which is the 82nd CE rating survey of CY Leung. Please follow normal academic standards when using or citing such data.

Abstract

POP interviewed 1,003 Hong Kong people between 5 and 8 October, 2015 by means of a random telephone survey conducted by real interviewers. Our latest survey conducted in early October shows that the popularity figures of CE CY Leung have slightly increased from late September. His latest support rating is 39.8, still more than 5 marks below the warning line of 45. His approval rate now stands at 24%, disapproval rate 62%, giving a net popularity of negative 38 percentage points. As for the Secretaries of Departments, the latest support rating of CS Carrie Lam is 57.4 marks, her approval rate is 52%, disapproval rate 16%, giving a net popularity of positive 35 percentage points. The latest support rating of FS John Tsang is 61.7 marks, approval rate 66%, disapproval rate 7%, thus a net popularity of positive 59 percentage points. As for SJ Rimsky Yuen, his support rating is 45.5 marks, approval rate 31%, disapproval rate 29%, giving a net popularity of positive 2 percentage points. In terms of popularity rating, John Tsang continues to be the most popular Secretary of Department. As for the Directors of Bureaux, compared to one month ago, the net approval rates of 5 among 12 Directors have gone up, while 5 have gone down and 2 remain unchanged. Among them, only Secretary for Food and Health Ko Wing-man registers significant change in his net approval rate, down by 6 percentage points. Among all the Directors, only Lau Kong-wah, Paul Chan and Eddie Ng register negative popularities, at negative 22, 31 and 36 percentage points respectively. Ko Wing-man continues to be the most popular Director in spite of his popularity drop, his net approval rate now stands at positive 65 percentage points. According to POP’s standard, Ko Wing-man falls under the category of “ideal” performer, John Tsang, Matthew Cheung and Carrie Lam fall under the category of “successful” performer. The performance of Ceajer Chan, Lai Tung-kwok, Anthony Cheung, Gregory So, Wong Kam-sing, Raymond Tam, Rimsky Yuen, Lau Kong-wah and Paul Chan can be labeled as “mediocre”. That of Clement Cheung can be labeled as “inconspicuous”. CY Leung and Eddie Ng fall into the category of “depressing” performer, while no one falls into that of “disastrous”. The maximum sampling errors of all approval and disapproval rates is +/-4 percentage points at 95% confidence level, while the sampling errors of rating figures and net approval rates need another calculation. The response rate of the survey is 64%. As the support rating of CE CY Leung continues to stand below the warning line of 45, Director of POP, Robert Chung, again reprints the abstracts of two articles written by him before on CE popularity, to discuss the possibility of a governance crisis. The articles can be downloaded in full from the POP Site.

Points to note:

[1] The address of the “HKU POP SITE” is http://hkupop.pori.hk, journalists can check out the details of the survey there.

[2] The sample size of this survey is 1,003 successful interviews, not 1,003 x 64.4% response rate. In the past, many media made this mistake.

[3] “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 of rating not more than +/-2.3, sampling error of percentages not more than +/-4%, and sampling error of net values not more than +/-7% at 95% confidence level”.

[4] Because of sampling errors in conducting the survey(s) and the rounding procedures in processing the data, the figures cannot be too precise, and the totals may not be completely accurate. Therefore, when quoting percentages of the survey(s), journalists should refrain from reporting decimal places, but when quoting the rating figures, one decimal place can be used.

[5] 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.

Latest Figures

POP today releases the latest popularity figures of CE CY Leung and various Secretaries of Departments and Directors of Bureaux under the accountability system. From 2014, POP enhanced the previous simple weighting method based on age and gender distribution to “rim weighting” based on age, gender and education (highest level attended) distribution. The latest figures released today have been rim-weighted according to provisional figures obtained from the Census and Statistics Department regarding the gender-age distribution of the Hong Kong population in 2015 mid-year and the educational attainment (highest level attended) distribution collected in the 2011 Census. Herewith the contact information for the latest survey:

[6] Errors are 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 sampling error. Sampling errors of ratings and net approval rates are calculated according to the distribution of the scores collected.

As different questions involve different sub-samples, the sampling 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:

[7] Based on 95% confidence interval.

Recent popularity figures of CE CY Leung are summarized as follows:

Date of survey	20-23/7/15	3-6/8/15	21-27/8/15	7-10/9/15	16-22/9/15	5-8/10/15	Latest change

[8] All error figures in the table are calculated at 95% confidence level. “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 rating not more than +/-1.9, sampling error of percentages not more than +/-3%, sampling error of net approval rates not more than +/-5% at 95% confidence level” when quoting the above figures. The error margin of previous survey can be found at the POP Site.

[9] Such changes have gone beyond the sampling errors at the 95% confidence level under the same weighting method, meaning that they are statistically significant prima facie. However, whether numerical differences are statistically significant or not is not the same as whether they are practically useful or meaningful.

Recent popularity figures of the three Secretaries of Departments under the accountability system are summarized below:

[10] The frequency of this series of questions is different from that of CE popularity ratings. Comparisons, if made, should be synchronized using the same intervals. Starting from 2011, these questions only uses sub-samples of the tracking surveys concerned, the sample size for each question also varies.

[11] All error figures in the table are calculated at 95% confidence level. “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 +/-2.3, sampling error of percentages not more than +/-4%, sampling error of net approval rates not more than +/-6% at 95% confidence level” when quoting the above figures. The error margin of previous survey can be found at the POP Site.

[12] Such changes have gone beyond the sampling errors at the 95% confidence level under the same weighting method, meaning that they are statistically significant prima facie. However, whether numerical differences are statistically significant or not is not the same as whether they are practically useful or meaningful.

Latest popularity figures of Directors of Bureaux under the accountability system are summarized below, in descending order of net approval rates:

[13] Starting from 2006, these questions only uses sub-samples of the tracking surveys concerned, the sample size for each question also varies.

Media can state “sampling error of percentages not more than +/-4% and sampling error of net approval rates not more than +/-7% at 95% confidence level” when quoting the above figures. The error margin of previous survey can be found at the POP Site.

However, whether numerical differences are statistically significant or not is not the same as whether they are practically useful or meaningful.

[16] Based on the figures in early September survey, in one decimal place, the respective net approval rates of Secretary for the Civil Service Clement Cheung and Secretary for Security Lai Tung-kwok are 15.5 and 14.6 percentage points. Thus, they ranked fifth and sixth at that time.

[17] Based on the figures of latest survey, in one decimal place, the respective net approval rates of Secretary for the Civil Service Clement Cheung and Secretary for Security Lai Tung-kwok are 13.4 and 13.2 percentage points. Thus, they are ranked fifth and sixth this time.

The latest survey showed that, CE CY Leung scored 39.8 marks, and 24% supported him as CE, his net approval rate is negative 38 percentage points. Meanwhile, the corresponding ratings of CS Carrie Lam, FS John Tsang and SJ Rimsky Yuen were 57.4, 61.7 and 45.5 marks, and 52%, 66% and 31% would vote for their reappointment correspondingly. Their net approval rates are positive 35, positive 59 and positive 2 percentage points respectively.

Commentary

Note: The following commentary was written by Director of POP, Robert Chung.

Our latest survey conducted in early October shows that the popularity figures of CE CY Leung have slightly increased from late September. His latest support rating is 39.8, still more than 5 marks below the warning line of 45. His approval rate now stands at 24%, disapproval rate 62%, giving a net popularity of negative 38 percentage points.

As for the Secretaries of Departments, the latest support rating of CS Carrie Lam is 57.4 marks, her approval rate is 52%, disapproval rate 16%, giving a net popularity of positive 35 percentage points. The latest support rating of FS John Tsang is 61.7 marks, approval rate 66%, disapproval rate 7%, thus a net popularity of positive 59 percentage points. As for SJ Rimsky Yuen, his support rating is 45.5 marks, approval rate 31%, disapproval rate 29%, giving a net popularity of positive 2 percentage points. In terms of popularity rating, John Tsang continues to be the most popular Secretary of Department.

As for the Directors of Bureaux, compared to one month ago, the net approval rates of 5 among 12 Directors have gone up, while 5 have gone down and 2 remain unchanged. Among them, only Secretary for Food and Health Ko Wing-man registers significant change in his net approval rate, down by 6 percentage points. Among all the Directors, only Lau Kong-wah, Paul Chan and Eddie Ng register negative popularities, at negative 22, 31 and 36 percentage points respectively. Ko Wing-man continues to be the most popular Director in spite of his popularity drop, his net approval rate now stands at positive 65 percentage points.

According to POP’s standard, Ko Wing-man falls under the category of “ideal” performer, John Tsang, Matthew Cheung and Carrie Lam fall under the category of “successful” performer. The performance of Ceajer Chan, Lai Tung-kwok, Anthony Cheung, Gregory So, Wong Kam-sing, Raymond Tam, Rimsky Yuen, Lau Kong-wah and Paul Chan can be labeled as “mediocre”. That of Clement Cheung can be labeled as “inconspicuous”. CY Leung and Eddie Ng fall into the category of “depressing” performer, while no one falls into that of “disastrous”.

The following table summarizes the grading of CE and the principal officials for readers’ easy reference:

“ Ideal ” : those with approval rates of over 66%; ranked by their approval rates shown inside brackets

Secretary for Food and Health Ko Wing-man (73%)

“ Successful ” : those with approval rates of over 50%; ranked by their approval rates shown inside brackets

FS John Tsang Chun-wah (66%); Secretary for Labour and Welfare Matthew Cheung Kin-chung (53%); CS Carrie Lam Cheng Yuet-ngor (52%)

“ Mediocre ” : those not belonging to other 5 types; ranked by their approval rates shown inside brackets

Secretary for Financial Services and the Treasury Ceajer Chan Ka-keung (43%); Secretary for Security Lai Tung-kwok (40%); Secretary for Transport and Housing Anthony Cheung Bing-leung (39%); Secretary for Commerce and Economic Development Gregory So Kam-leung (33%); Secretary for the Environment Wong Kam-sing (32%); Secretary for Constitutional and Mainland Affairs Raymond Tam Chi-yuen (31%) [18]; SJ Rimsky Yuen Kwok-keung (31%)[18]; Secretary for Home Affairs Lau Kong-wah (23%); Secretary for Development Paul Chan Mo-po (18%)

“ Inconspicuous ” : those with recognition rates of less than 50%; ranked by their approval rates; the first figure inside bracket is approval rate while the second figure is recognition rate

Secretary for the Civil Service Clement Cheung Wan-ching (20%, 27%)

“ Depressing ” : those with disapproval rates of over 50%; ranked by their disapproval rates shown inside brackets

CE Leung Chun-ying (62%); Secretary for Education Eddie Ng Hak-kim (54%)

“ Disastrous ” : those with disapproval rates of over 66%; ranked by their disapproval rates shown inside brackets

[18] In one decimal place, the respective approval rates of Secretary for Constitutional and Mainland Affairs Raymond Tam Chi-yuen and SJ Rimsky Yuen Kwok-keung are 30.7% and 30.5%.

Since the support rating of CE CY Leung continues to stand below the warning line of 45, I reprint again the abstracts of two articles written by me before on CE popularity for public reference, to discuss the possibility of a governance crisis. The articles can be downloaded in full from the POP Site.

“The Popularity of Tung Chee-hwa from All Angles” (released on 14/5/2003): “According to our experience, a political figure with less than 50 marks can be said to have fallen into negative popularity, while a score of less than 45 marks can indicate credibility crisis. Using this analysis, Tung has been negatively popular among the general public since August 2002, and in March 2003, he has sunk into a credibility crisis…”

“New Perspectives on Chief Executive Ratings” (released on 12/6/2003): “Concurrent tests showed that a support rating of 55 marks was more or less equivalent to a ‘vote share’ of 45%, 50 marks could be converted to round about 30%, 45 marks to 20%, and 40 marks to 10% to 15%... In late 1990, after the ‘approval rate’ of Margaret Thatcher sank to 25%, she withdrew from the election for the leader of the British Conservative Party, thereby gave up her job as the Prime Minister of UK, a post which she held since 1979. In early 1997, John Major lost his post of Prime Minister to Tony Blair, after his ‘approval rate’ hovered around the level of 30% for a long time. As for former USA President Bill Clinton, his lowest ever ‘approval rate’ within his 8-year terms of office was as high as 37%...”
