Special Announcement

To facilitate academic study and rational discussion, the Public Opinion Programme (POP) of The University of Hong Kong has already released for public examination some time ago via the HKU POP SITE” (http://hkupop.hku.hk) the raw data of all 74 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. Please follow normal academic standards when using or citing such data.



Abstract

POP interviewed 1,003 Hong Kong people between 15 and 18 June by means of a random telephone survey conducted by real interviewers. According to our latest survey, whether in terms of absolute rating or dichotomous contrast, people’s feeling of identity towards “Hongkongers” has receded, while that of “Chinese” has recovered, back to the level registered near mid-2014. On a scale of 0-10 measuring the absolute strength of identity, the identity rating of “Hongkongers” stands at 7.95, that of “members of the Chinese race” stands at 7.02, “Chinese” 6.70, and “citizens of PRC” 5.87. When importance ratings are incorporated to generate “identity indices” between 0 and 100 (the higher the index, the stronger the positive feeling), Hong Kong people’s feeling is still the strongest as “Hongkongers”, at 77.6 marks, followed by “Asians” 72.3, then “members of the Chinese race” 67.3, “Chinese” 65.3, “global citizens” 64.1, and finally “citizens of the PRC” 55.9. If we follow the usual study method of using a dichotomy of “Hongkonger” versus “Chinese” to measure Hong Kong people’s ethnic identity, the proportion of people identifying themselves as “Hongkongers” outnumbers that of “Chinese” both in their narrow and broad senses by 14 to 29 percentage points. All in all, Hong Kong people feel the strongest as “Hongkongers”, then followed by a number of cultural identities. The feeling of being “citizens of the PRC” is the weakest among all identities tested. The maximum sampling error of percentages is +/-4 percentage points at 95% confidence level, while the sampling error of rating figures needs another calculation. The response rate of the survey is 66%.

 

Points to note:

[1] The address of the “HKU POP SITE” is http://hkupop.hku.hk, journalists can check out the details of the survey there.
[2] The sample size is 1,003 successful interviews, not 1,003 x 65.6% response rates. In the past, many media made this mistake.
[3] The maximum sampling error of all percentages is +/-4 percentage points at 95% confidence level, while the sampling error of rating figure 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 various ratings not more than +/-0.26, sampling error of identity indices not more than +/-2.5, and sampling error of percentages not more than +/-4% at 95% confidence level”. Because POP introduced “rim weighting” in 2014, during the transition period, whether changes in various figures are beyond sampling errors are based on tests using the same weighting methods. That is, to test whether the first set of figures collected in 2014 is significantly different from that of the previous survey, both sets of data are rim weighted before testing, instead of using simple computation of the published figures.
[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.
[6] Starting from 18 June 2013, in light of their popular usage, the following translations are used in reports and releases: 香港人 = Hongkonger, 中國的香港人 = Hongkonger in China, 中國人 = Chinese, 香港的中國人 = Chinese in Hong Kong.



Latest Figures

POP today releases via the POP Site the latest survey on people’s ethnic identity. 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 latest contact information:

[7] 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 sample error. Sampling errors of ratings are calculated according to the distribution of the scores collected.

[8] Since December 2008, the sub-sample size of the series of questions is controlled at slightly over 500 cases. The sub-sample sizes of this survey range from 648 to 721, and the increased sampling errors have already been reflected in the figures tabulated. 
[9] ] 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 ratings not more than +/-0.26 and sampling error of identity indices not more than +/-2.5 at 95% confidence level” when quoting the above figures. The error margin of previous survey can be found at the POP Site.
[10] New items since December 2008. “Identity index” is calculated for each identity of a respondent by taking the geometric mean of the strength and importance ratings of a certain identity, multiply by 10. If either the strength or importance rating of a respondent is missing, it is substituted by the sample mean of that identity.
[11] 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 above figures were collected from independent rating questions, but not involving the dichotomy issue of “Hongkongers” and “Chinese”. Latest findings showed that the identity ratings for “Hongkongers”, “Asians” and “members of the Chinese race” were 7.95, 7.81 and 7.02 marks respectively. Using the same rating method, the strength of people’s identity as “global citizens”, “Chinese” and “citizens of PRC” were 6.73, 6.70 and 5.87 marks respectively. As for the importance ratings, “Hongkongers”, “Asians” and “members of the Chinese race” scored 7.79, 7.00 and 6.65 marks respectively, while those for “Chinese” , “global citizens” and “citizens of PRC” were 6.62, 6.33 and 5.60 marks respectively.

 

Taking the geometric mean of the strength and importance ratings of each respondent and then multiply it by 10, we have an “identity index” for the respondent for a certain identity between 0 and 100, with 0 meaning no feeling, 100 meaning extremely strong feeling, and 50 meaning half and half. Using these identity indices, the rank order of Hong Kong people’s six identities was “Hongkongers”, “Asians”, “members of the Chinese race”, “Chinese” , “global citizens” and “citizens of PRC”. Their scores were 77.6, 72.3, 67.3, 65.3, 64.1 and 55.9 marks respectively.

[12] Starting from June 2011, this question only uses sub-samples of the tracking surveys concerned. The sub-sample size of this survey is 660, and the increased sampling errors have already been reflected in the figures tabulated. 
[13] 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 percentages not more than +/-4% at 95% confidence level” when quoting the above figures. The error margin of previous survey can be found at the POP Site.
[14] This means the percentage of “Hongkongers in China” plus “Chinese in Hong Kong”.
[15] 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.


When asked to make a choice among 4 given identities, namely, “Hongkongers”, “Hongkongers in China”, “Chinese” and “Chinese in Hong Kong”, 36% of the respondents identified themselves as “Hongkongers”, 22% as “Chinese”, 27% as “Hongkongers in China”, while 13% identified themselves as “Chinese in Hong Kong”. In other words, 64% of the respondents identified themselves as “Hongkongers” in the broader sense (i.e. either as “Hongkongers” or “Hongkongers in China”), whereas 35% identified themselves as “Chinese” in the broader sense (i.e. either as “Chinese” or “Chinese in Hong Kong”), 41% chose a mixed identity of “Hongkongers plus Chinese” (i.e. either as “Hongkongers in China” or “Chinese in Hong Kong”).

 

Because the concepts of “Hongkongers”, “Hongkongers in China”, “Chinese” and “Chinese in Hong Kong” may overlap with each other, and making a one-in-four choice may not reflect the actual strengths of one’s ethnic identities, POP has right from the beginning conducted parallel tests on the strengths of people’s separate identities as “Hongkongers” and “Chinese” using a scale of 0-10, to study ethnic identity in different levels. In June 2007, POP has already expanded its study to include four new identities for strength rating, namely, “citizens of PRC”, “members of the Chinese race”, “Asians” and “global citizens”. In December 2008, the study was further expanded by including separate importance ratings for different identities, and the compilation of a separate index for each identity using geometric means. Though they may not be perfect, the complex studies adopted by POP were already very comprehensive.


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 some of the polling items covered in this press release, the previous survey was conducted from December 10 to 16, 2014 while this survey was conducted from June 15 to 18, 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.

Commentary

Robert Chung, Director of Public Opinion Programme, observed, “According to our latest survey, whether in terms of absolute rating or dichotomous contrast, people’s feeling of identity towards ‘Hongkongers’ has receded, while that of ‘Chinese’ has recovered, back to the level registered near mid-2014. On a scale of 0-10 measuring the absolute strength of identity, the identity rating of ‘Hongkongers’ stands at 7.95, that of ‘members of the Chinese race’ stands at 7.02, ‘Chinese’ 6.70, and ‘citizens of PRC’ 5.87. When importance ratings are incorporated to generate ‘identity indices’ between 0 and 100 (the higher the index, the stronger the positive feeling), Hong Kong people’s feeling is still the strongest as ‘Hongkongers’, at 77.6 marks, followed by ‘Asians’ 72.3, then ‘members of the Chinese race’ 67.3, ‘Chinese’ 65.3, ‘global citizens’ 64.1, and finally ‘citizens of the PRC’ 55.9. If we follow the usual study method of using a dichotomy of ‘Hongkonger’ versus ‘Chinese’ to measure Hong Kong people’s ethnic identity, the proportion of people identifying themselves as ‘Hongkongers’ outnumbers that of ‘Chinese’ both in their narrow and broad senses by 14 to 29 percentage points. All in all, Hong Kong people feel the strongest as ‘Hongkongers’, then followed by a number of cultural identities. The feeling of being ‘citizens of the PRC’ is the weakest among all identities tested. As for the reasons behind the ups and downs of these figures, we will leave it to our readers to form their own judgment using the detailed records displayed in our ‘Opinion Daily’.”
