HKU POP releases popularity figures of CE and the GovernmentBack

To facilitate academic study and rational discussion, Public Opinion Programme (POP) at 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 70 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 71st CE rating survey of CY Leung. Please follow normal academic standards when using or citing such data.

POP interviewed 1,070 Hong Kong people between 20 and 26 April 2015 by means of a random telephone survey conducted by real interviewers. Our latest survey shows CE CY Leung’s overall popularity has slightly increased from early April. His support rating is now 44.5, but still below the 45 mark alert level. His approval rate now stands at 26%, disapproval rate 56%, giving a net popularity of negative 30 percentage points. As for the SAR Government, its popularity has increased significantly compared to a month ago, its satisfaction rate now stands at 31%, dissatisfaction rate at 40%, giving a net satisfaction rate of negative 9 percentage points, representing a jump of 13 percentage points in one month. Indepth analysis shows that those aged between 18 and 29 are most critical of CY Leung as CE, and most dissatisfied with the performance of the SAR Government. 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 again, 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.

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 2014 year-end and the educational attainment (highest level attended) distribution collected in the 2011 Census. Herewith the contact information of various surveys:

[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.

Recent popularity figures of CE CY Leung and people’s satisfaction of the overall performance of the HKSAR Government are summarized as follows:

[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 +/-1.8, sampling error of percentages not more than +/-4%, sampling error of net values 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.
[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 676.
[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 44.5 marks, and 26% supported him as CE, his net approval rate is negative 30 percentage points. Regarding people’s appraisal of the overall performance of the HKSAR Government, the latest figures revealed that 31% were satisfied, whereas 40% were dissatisfied, thus net satisfaction stands at negative 9 percentage points. The mean score is 2.7, 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. Herewith further analysis of the support rate of Leung Chun-ying as Chief Executive and the satisfaction rate of SARG performance by respondents’ age, with sub-sample size placed in brackets:

[10] Differences among sub-groups are tested to be statistically significant at 95% confidence level.

[11] Differences among sub-groups are tested to be statistically significant at 95% confidence level.

Opinion Daily

In January 2007, POP opened a feature page called “Opinion Daily” at the “POP Site”, to record significant events and selected polling figures on a day-to-day basis, in order to let readers judge by themselves the reasons for the ups and downs of different opinion figures. In July 2007, POP collaborated with Wisers Information Limited whereby Wisers supplies to POP each day starting from July 24, a record of significant events of that day, according to the research method designed by POP. These daily entries would be uploaded to “Opinion Daily” as soon as they are verified by POP.

For the polling items covered in this press release, the previous survey of some items was conducted from 16 to 19 March, 2015 while this survey was conducted from 20 to 26 April, 2015. During this period, herewith the significant events selected from counting newspaper headlines and commentaries on a daily basis and covered by at least 25% of the local newspaper articles. Readers can make their own judgment if these significant events have any impacts to different polling figures.

Robert Ting-Yiu Chung, Director of POP, observed, “Our latest survey shows CE CY Leung’s overall popularity has slightly increased from early April. His support rating is now 44.5, but still below the 45 mark alert level. His approval rate now stands at 26%, disapproval rate 56%, giving a net popularity of negative 30 percentage points.

Indepth analysis shows that those aged between 18 and 29 are most critical of CY Leung as CE, and most dissatisfied with the performance of the SAR Government. 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 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 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%...”
