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 82 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 83rd CE rating survey of CY Leung. Please follow normal academic standards when using or citing such data.
Abstract
POP interviewed 1,007 Hong Kong people between 19 and 23 October 2015 by means of a random telephone survey conducted by real interviewers. Our latest survey shows that CE CY Leung’s popularity figures have slightly increased from early October, but all changes are within sampling errors. His support rating now stands at 41.3 marks, still below the warning line of 45. Leung’s approval rate now stands at 24%, disapproval rate 59%, giving a net popularity of negative 35 percentage points. As for the SAR Government, its popularity continues to increase compared to a month ago, but all changes registered are also within sampling errors. Its satisfaction rate now stands at 25%, dissatisfaction rate 47%, giving a net satisfaction rate of negative 22 percentage points. Indepth analysis shows that the younger and the more educated the respondents, the more critical they are of CY Leung as CE in terms of both support rate and rating. The maximum sampling error of all percentage figures is +/-4 percentage points at 95% confidence level, while the sampling error of rating figures and net values need another calculation. The response rate of the survey is 67%. As the support rating of CE CY Leung continues to stand below the warning line of 45, Research Manager of POP, Frank Lee, reprints the abstracts of two articles written by Director of POP, Robert Chung, 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 1,007 successful interviews, not 1,007 x 66.8% response rate. In the past, many media made this mistake.
[3] The maximum sampling error of percentages is +/-4 percentage points at 95% confidence level, while the sampling error of rating figure and net value needs another calculation. “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 +/-1.9 and sampling error of percentages not more than +/-4%, 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 on schedule via the “POP SITE” the latest popularity figures of CE CY Leung and the HKSAR Government. 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 are calculated according to the distribution of the scores collected.

[7] 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 +/-4%, sampling error of net values 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.
[8] Collapsed from a 5-point scale. The mean value is calculated by quantifying all individual responses into 1, 2, 3, 4, 5 marks according to their degree of positive level, where 1 is the lowest and 5 the highest, and then calculate the sample mean. Starting from March 2011, this question only uses sub-samples of the tracking surveys concerned. The sample size for this series is 606.
[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.
The latest survey showed that, CE Leung Chun-ying scored 41.3 marks, and 24% supported him as CE, his net approval rate is negative 35 percentage points. Regarding people’s appraisal of the overall performance of the HKSAR Government, the latest figures revealed that 25% were satisfied, whereas 47% were dissatisfied, thus net satisfaction stands at negative 22 percentage points. The mean score is 2.5, which is in between “quite dissatisfied” and “half-half”.
Indepth Analysis
In the survey, we also asked respondents for their age. If they were reluctant to give their exact age, they could give us a range.

Commentary
Frank Wai-Kin Lee, Research Manager of POP, observed, “Our latest survey shows that CE CY Leung’s popularity figures have slightly increased from early October, but all changes are within sampling errors. His support rating now stands at 41.3 marks, still below the warning line of 45. Leung’s approval rate now stands at 24%, disapproval rate 59%, giving a net popularity of negative 35 percentage points. As for the SAR Government, its popularity continues to increase compared to a month ago, but all changes registered are also within sampling errors. Its satisfaction rate now stands at 25%, dissatisfaction rate 47%, giving a net satisfaction rate of negative 22 percentage points. Indepth analysis shows that the younger and the more educated the respondents, the more critical they are of CY Leung as CE in terms of both support rate and rating. As for the reasons affecting the ups and downs of these figures, we leave it to our readers to form their own judgment using detailed records displayed in our ‘Opinion Daily’. Since the support rating of CE CY Leung continues to stand below the warning line of 45, I reprint the abstracts of two articles written by Robert Ting-Yiu Chung, Director of POP, 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%...”
