2016 LC Election Survey sponsored by HK01返回

Research Background

HK01 commissioned Public Opinion Programme at The University of Hong Kong in June 2016 to conduct this survey on 6 to 7 June 2016 with 540 Cantonese-speaking registered voters living in Hong Kong aged 18 or above. The goal is to gauge Hong Kong people’s views on 2016 Legislative Council Election.

The research instrument used in this study was designed entirely by the POP Team after consulting HK01. Fieldwork operations and data analysis were conducted independently by the POP Team, without interference from any outside party. In other words, POP was given full autonomy to design and conduct the survey, and POP would take full responsibility for all the findings reported herewith.

Research Design

Telephone interviews were conducted by interviewers under close supervision. All data were collected by our interviewers using a Computer Assisted Telephone Interview (CATI) system invented by the research team which allowed real-time data capture and consolidation. To ensure data quality, on top of on-site supervision, voice recording, screen capturing and camera surveillance were used to monitor the interviewers' performance.

Telephone numbers are randomly generated using known prefixes assigned to telecommunication services providers under the Numbering Plan provided by the Office of the Communications Authority (OFCA). Invalid numbers are then eliminated according to computer and manual dialing records to produce the final sample.

The target population of this survey was Cantonese-speaking registered voters living in Hong Kong aged 18 or above. If more than one eligible subject had been available, selection was made using the “next birthday rule” which selected the person who had his/her birthday next. The survey was conducted on 6 to 7 June 2016. A total of 540 eligible respondents were successfully interviewed. The effective response rate of this survey was 71.2%, and the standard sampling error for percentages based on this sample was less than 2.2 percentage points. In other words, the sampling error for all percentages using the total sample was less than plus/minus 4.3 percentage points at 95% confidence level.

To ensure representativeness of the findings, the raw data collected have been rim-weighted according to the distribution of age, gender and geographic constituency of registered voters in the 2016 provisional register of electors provided by the Registration and Electoral Office.
