Press Release on October 15, 2015
| Detailed Findings (Public Sentiment Index Feature Page) |
Background
The Public Sentiment Index (PSI) compiled by Public Opinion Programme (POP) at The University of Hong Kong 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, except under special circumstances.
Cut-off date of the PSI figures released by POP today is October 11, 2015, while that of the next round of release will be October 25, 2015. The tentative release date for the next release will be October 29, 2015 (Thursday).
Latest Figures
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. The PSI released by POP today shows that as of October 11, 2015, the latest Public Sentiment Index (PSI) is 63.3, down 2.1 from late-September. As for the Government Appraisal (GA) and Society Appraisal (SA), the scores are 72.1 and 75.0, down 1.8 and 1.3 respectively. The chart of PSI, GA and SA are shown below:

The latest PSI of 63.3 can be considered as among the worst 1% across the past 20 years or so, while the GA and SA scores of 72.1 and 75.0 can be considered as among the worst 3% and 5% respectively.
Commentary
Edward Chit-Fai Tai, Senior Data Analyst of Public Opinion Programme, observed, “Hong Kong’s Public Sentiment Index (PSI) continues to drop in early October. The latest PSI reading goes down 2.1 points from two weeks ago to 63.3 points. It can be considered as among the worst 1% across the past 20 years or so. The latest drop in PSI is attributable to the decreases in both component scores. The Society Appraisal (SA) Score that reflects people’s appraisal of the social environment goes down 1.3 points to 75.0 points, whereas the Government Appraisal (GA) Score that reflects people’s appraisal of society’s governance goes down 1.8 points to 72.1 points. The SA and the GA Scores can be considered as among the worst 5% and 3% over the past 20 years or so respectively. 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 the ‘Opinion Daily’ of our POP Site.”
