HKU POP: PSI plungesBack
|Press Release on July 17, 2014|
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 peoples’ appraisal of society’s governance while SA refers to peoples’ 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.hku.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 July 13, 2014, while that of the next round of release will be July 27, 2014. The tentative release date for the next release will be July 31, 2014 (Thursday).
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 2013 year-end and the educational attainment (highest level attended) distribution collected in the 2011 Census. The PSI released by POP today shows that as of July 13, 2014, the latest Public Sentiment Index (PSI) is 65.9, down 8.1 from late-June. As for the Government Appraisal (GA) and Society Appraisal (SA), the scores are 74.6 and 76.3, down 6.0 and 5.9 respectively. The monthly average charts of PSI, GA and SA are shown below:
As for the meaning of the score values, please refer to the following:
The latest PSI of 65.9 can be considered as among the worst 1% across the past 20 years, while the GA and SA scores of 74.6 and 76.3 can be considered as among the worst 5% and 6% respectively.
Recent values of PSI, GA, SA and 10 fundamental figures are tabulated as follows:
 POP will adopt the latest published weighting index figures when there are no respective updates.
Recent average PSI, GA and SA figures per month are tabulated as follows:
Frank Lee, Research Manager of Public Opinion Programme, observed, “Hong Kong’s Public Sentiment Index (PSI) plunges by 8.1 points to 65.9 after ‘July 1st’ and before the Government’s delivery of its political reform report, back to the under 70 level registered late last year. The latest PSI reading can be considered as among the worst 1% across the past 20 years or so, mainly due to people’s worsened appraisal towards the CE and overall governance. The latest Government Appraisal (GA) and Society Appraisal (SA) scores have dropped to 74.6 and 76.3 respectively, and can be considered as among the worst 5% and 6% across the past 20 years or so. 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.”
