The Public Opinion Programme at the University of Hong Kong interviewed 1,026 Hong Kong people between 18-20 March by means of a random telephone survey conducted by real interviewers. The survey finds that people's satisfaction with Legco members in general is approaching record high again, but their satisfaction with the Police Force has dropped to the level registered in July 2004, probably triggered by the dispute over the way it has handled the case of online artists' nude photographs. People's satisfaction with the PLA Hong Kong Garrison has also slightly dropped, while dissatisfaction remained almost zero. Programme Director Robert Chung stresses that people's satisfaction with Legco members in general includes those returned by geographical and functional constituencies, it is not a direct measurement of individual Legco members' performance. The sampling error of the survey is below +/-3 percentage points at 95% confidence level, response rate being 66%.
Points to note:
* The address of the "HKU POP SITE" is http://hkupop.pori.hk, journalists can check out the details of the survey there.
* The sample size of this survey is 1,026 successful interviews, not 1,026 x 65.7% response rate. In the past, many media made this mistake.
* The maximum sampling error of all percentages is between +/-1 to 3 percentage points 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. When quoting these figures, journalists can state "sampling error of percentages not more than +/-3% at 95% confidence level".
* When quoting figures of this survey, journalists should refrain from reporting the decimal places, because sampling errors do not entail this kind of precision.
* 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.

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. Our purpose is to provide readers with accurate information so that they can judge by themselves the reasons for the ups and downs of different opinion figures. When "Opinion Daily" began to operate on January 17, 2007, it only contained significant events and popularity figures of the Chief Executive over the past few months. As of today, it contains a chronology of events starting from May 1, 2006, and many poll figures registered since January 1, 2006. Readers can now check on the results of 9 different polling items compiled by POP, including the popularity of the Chief Executive, the HKSAR government, and the Secretaries of Departments under the accountability system. In near future, the content of 「Opinion Daily」 will continue to expand, in order to promote the science of opinion polling.
In July 2007, POP collaborated with Wisers Information Limited whereby Wisers supplies to POP since July 24 each day a record of significant events of that day, according to the research method designed by POP. These daily entries would be uploaded to the 「Opinion Daily」 feature page as soon as they are verified by POP, in order to provide readers with swifter and more accurate information.
In August 2007, POP began to include in its regular press releases a list of significant events which happened in between two surveys, so that readers can make their own judgment on whether these events have any effect on the ups and downs of the polling figures. This press release is no exception.
For the polling items covered in this press release, the previous survey was conducted from December 19 to 24, 2007 while this survey was conducted from March 18 to 20, 2008. In between these two surveys, 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.

Commentary
Robert Ting-Yiu Chung, Director of Public Opinion Programme, observed, "After people's satisfaction with Legco members in general reached record high in September last year, counting from the operation of the first SAR Legco, it dropped again at the end of last year. However, our latest survey shows that people's satisfaction has risen again in March, to almost record high. As for the two disciplinary forces, our survey shows that people's satisfaction with the Hong Kong Police Force has dropped significantly compared to three months ago, down to the level registered in July 2004. The drop was probably triggered by the dispute over the way Hong Kong Police has handled the case of online artists' nude photographs. On the other hand, people's satisfaction with the PLA Hong Kong Garrison has also dropped slightly, but within sampling error, while dissatisfaction rate remains almost zero. As for the reasons affecting the ups and downs of these figures, we leave it to our readers to form their own judgment using the detailed records displayed in our 'Opinion Daily'. It should be noted, however, people's satisfaction with Legco members in general includes those returned by geographical as well as functional constituencies. It is not a direct measurement of individual Legco members' performance."

About HKUPOP
People's satisfaction with the performance of Legislative Council members, Hong Kong Police Force and PLA's Hong Kong Garrison survey
Regarding the development of our surveys on people's satisfaction with the performance of Legislative Council members, Hong Kong Police Force and PLA's Hong Kong Garrison, we have explained it in our press release of October 3, 2006, January 2, April 10, July 10, October 2, 2007 as well as January 4, 2008. Today, we post it again to give readers a more comprehensive picture of such developments.
(1) Mapping people's satisfaction with the performance of Legislative Council members
- The First Legislative Council of the HKSAR was formed one year after the handover of Hong Kong. In July 1998, HKUPOP began our regular surveys on people's satisfaction with the performance of Legislative Council members in general. When the Second Legislative Council was formed two years later, we simply changed the name of the survey from "First Legco" to "Second Legco", without changing the research design. In October 2004, the "Third Legco" subsequently replaced the "Second Legco". From the beginning to its end, the "First Legco" surveys were conducted once every month. For the "Second Legco" surveys, the frequency was changed to once every two months until July 2003. Thereafter, the "Third Legco" surveys are conducted once every three months to cope with the changing social conditions.
- The question wordings used in the questionnaire are "Are you satisfied with the overall performance of the members of HKSAR Legislative Council?". Interviewers then probed respondents' degree of satisfaction and respondents could choose a single response ranged from "very satisfied", "quite satisfied", "half-half", "not quite satisfied" to "very dissatisfied".
(2) Mapping people's satisfaction with the performance of the Hong Kong Police Force and PLA's Hong Kong Garrison
- Shortly after the handover of Hong Kong in July 1997, HKUPOP began our regular surveys on people's satisfaction with the performance of the Hong Kong Police Force and PLA's Hong Kong Garrison. From the beginning, the surveys were conducted once every month. Then in September 2000 the frequency was changed to once every two months. Since October 2003, the surveys have been conducted once every three months to cope with the changing social conditions.
- The question wordings used in the questionnaire are "Are you satisfied with the performance of the Hong Kong Police Force / People's Liberation Army Hong Kong Garrison?" Interviewers then probed respondents' degree of satisfaction and respondents could choose a single response ranged from "very satisfied", "quite satisfied", "half-half", "not quite satisfied" to "very dissatisfied".
Before May 2000, the sample size of our regular surveys was set at slightly over 500, we increased it to at least 1,000 after that. The above surveys are no exceptions. The findings of these surveys are now published regularly on-line at our HKU POP Site, while all previous findings published via our newsletter POP Express have also been uploaded on-line in various formats.
