Special Announcements
1. From July 2017, apart from sampling landline numbers to conduct opinion surveys, the Public Opinion Programme (POP) of The University of Hong Kong has also added mobile numbers to the sampling frame. After three months of testing, in October 2017, POP formalized the use of mixed samples as its standard for regular opinion surveys using a landline and mobile sample ratio of 4 to 1. Starting from April 2018, POP further increased the proportion of mobile sample, which the landline and mobile sample ratio became 2 to 1. The figures released today by POP have already incorporated landline and mobile samples.
2. To facilitate academic study and rational discussion, POP today released via the "HKU POP SITE" (http://hkupop.pori.hk) the raw data and related respondents' demographics of the latest rating survey of CE Carrie Lam, together with those of regular rating surveys of former CEs CH Tung, Donald Tsang and CY Leung released earlier, for public examination. Please follow normal academic standards when using or citing such data.
Abstract
POP interviewed 1,001 Hong Kong people between 16 and 19 April 2018 by means of a random telephone survey conducted by real interviewers. Our survey shows that the popularity figures of CE Carrie Lam have not changed much since two weeks ago. Her latest popularity rating is 53.9 marks. Her latest approval rate is 45%, disapproval rate 41%, giving a net popularity of positive 4 percentage points. Indepth analysis shows that the younger and the more educated the respondents, the more critical they are of Carrie Lam as CE in terms of both support rate and rating. As for the SAR Government, its satisfaction rate now stands at 35%, dissatisfaction rate 42%, giving a net satisfaction rate of negative 7 percentage points, representing a significant rebound of 11 percentage points compared to two weeks ago. As for people's trust in the government, the trust rate now stands at 43%, distrust rate 35%, giving a net trust of positive 8 percentage points, representing a significant rebound of 8 percentage points compared to two weeks ago. As for the society's appraisals, among economic, livelihood and political conditions, people remain to be least satisfied with the current political condition. The corresponding net satisfactions are positive 2, negative 23 and negative 47 percentage points. 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 56%.
As for the Public Sentiment Index (PSI), the latest PSI stands at 103.6, increased by 4.3 points since mid-April. This time both component scores of PSI have increased. Specifically, the Government Appraisal (GA) Score that reflects people's appraisal of society's governance goes up by 2.7 points to 102.0, whereas the Society Appraisal (SA) Score that reflects people's appraisal of the social environment increases by 5.1 points to 97.4.
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 1,001 successful interviews, not 1,001 x 56.4% 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 +/-1.7 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.
I. Popularity of CE and the Government
Latest Figures
POP today releases the latest popularity figures of CE Carrie Lam and the HKSAR Government. From July 2017, POP enhanced the previous weighting method that has been used for quite a few years. Apart from age, gender and education, economic activity group is now also taken into account when adjusting data. The latest figures released today have been rim-weighted according to figures collected in the 2016 By-census regarding the gender-age distribution of the Hong Kong population and the 2017 educational attainment (highest level attended) distribution and economic activity status distribution obtained from the Census and Statistics Department. The mobile sample has also been rim-weighted according to the basic Public Sentiment Index (PSI) figures collected in the landline sample. 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 +/-1.7, 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. This question only uses sub-samples of the tracking surveys concerned. The sample size for this series is 632.
[9] Such changes have gone beyond the sampling errors at the 95% confidence level, meaning that they are statistically significant prima facie. However, whether numerical differences are statistically significant is not the same as whether they are practically useful or meaningful, and different weighting methods could have been applied in different surveys.
The latest survey showed that CE Carrie Lam scored 53.9 marks, and 45% supported her as CE, her net approval rate is positive 4 percentage points. Regarding people's appraisal of the overall performance of the HKSAR Government, the latest figures revealed that 35% were satisfied, whereas 42% were dissatisfied, thus net satisfaction stands at negative 7 percentage points. The mean score is 2.8, which is close to "half-half". Meanwhile, 43% of the respondents trusted the HKSAR Government, the net trust value is positive 8 percentage points, while the mean score is 3.0, which is close to "half-half". As for people's satisfaction with the current economic, livelihood and political conditions, the latest satisfaction rates were 41%, 28% and 17% respectively, while their net satisfaction rates in these conditions were positive 2, negative 23 and negative 47 percentage points. The mean scores of the economic, livelihood and political conditions were 2.9, 2.6 and 2.1, meaning between "half-half" and "quite dissatisfied" in general.
Indepth Analysis
In the survey, we also asked respondents for their age and education attainment. If they were reluctant to give their exact age, they could give us a range.

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 was conducted from 2 to 4 April, 2018 while this survey was conducted from 16 to 19 April, 2018. 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.

II. Public Sentiment Index
Background
The Public Sentiment Index (PSI) compiled by POP aims at quantifying Hong Kong people's sentiments, in order to explain and predict the likelihood of collective behaviour. PSI comprises 2 components: one being Government Appraisal (GA) Score and the other being Society Appraisal (SA) Score. GA refers to people's appraisal of society's governance while SA refers to people's appraisal of the social environment. Both GA and SA scores are compiled from a respective of 4 and 6 opinion survey figures. All PSI, GA and SA scores range between 0 to 200, with 100 meaning normal, the grading reference of the scores are shown below. For methodological detailed please refer to the HKU POP Site at http://hkupop.pori.hk.
POP started to pilot study the "Public Sentiment Index" in year 2010 in collaboration with NowTV. The first survey was conducted in June 2010, followed by a series of monthly tracking surveys in 2011. There were altogether 13 surveys, covered by 11 releases from March 2011 to January 2012. All results have been uploaded to the POP Site.
At the end of June 2012, before the 15th anniversary of the handover of Hong Kong, POP officially released a "PSI analysis" with figures dating back to 1992, spanning over 20 years. Moreover, the frequency of the study was set at twice a month. In October 2012, echoing the start of a new Legislative Council, POP decided to set the cut-off date of all PSI analyses at the Sunday proceeding every 15th and last day of month, whereas the release date was set at the first Thursday following the cut-off date. In July 2017, after the 20th anniversary of the handover, POP further streamlined the release date and mode of PSI analyses to become POP Site release only for the first analysis of each month, and POP Site plus press release for the second analysis of each month. At the same time, the second release was shifted to the first Tuesday of the following month, except under special circumstances.
Cut-off date of the PSI figures released by POP today is April 29, 2018, while that of the next round of release will be May 13, 2018. The tentative release date for the next release will be May 17, 2018 (Thursday).
Latest Figures of PSI
The PSI released by POP today shows that as of April 29, 2018, the latest Public Sentiment Index (PSI) is 103.6, up 4.3 from mid-April. As for the Government Appraisal (GA) and Society Appraisal (SA), the scores are 102.0 and 97.4, up 2.7 and 5.1 respectively. The chart of PSI, GA and SA are shown below:

Commentary
Note: The following commentary was written by Senior Data Analyst of POP, Edward Tai.
Our latest survey conducted in mid-April shows that the popularity figures of CE Carrie Lam have not changed much since two weeks ago. Her latest popularity rating is 53.9 marks. Her latest approval rate is 45%, disapproval rate 41%, giving a net popularity of positive 4 percentage points. Indepth analysis shows that the younger and the more educated the respondents, the more critical they are of Carrie Lam as CE in terms of both support rate and rating.
As for the SAR Government, its satisfaction rate now stands at 35%, dissatisfaction rate 42%, giving a net satisfaction rate of negative 7 percentage points, representing a significant rebound of 11 percentage points compared to two weeks ago. As for people's trust in the government, the trust rate now stands at 43%, distrust rate 35%, giving a net trust of positive 8 percentage points, representing a significant rebound of 8 percentage points compared to two weeks ago. As for the society's appraisals, among economic, livelihood and political conditions, people remain to be least satisfied with the current political condition. The corresponding net satisfactions are positive 2, negative 23 and negative 47 percentage points.
As for the Public Sentiment Index (PSI), the latest PSI stands at 103.6, increased by 4.3 points since mid-April. This time both component scores of PSI have increased. Specifically, the Government Appraisal (GA) Score that reflects people's appraisal of society's governance goes up by 2.7 points to 102.0, whereas the Society Appraisal (SA) Score that reflects people's appraisal of the social environment increases by 5.1 points to 97.4. 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".
