Research Background

The Hong Kong Jockey Club Disaster Preparedness and Response Institute (HKJCDPRI) commissioned Public Opinion Programme at The University of Hong Kong in September 2018 to conduct a public opinion poll to understand the general Hong Kong public’s awareness of typhoon precautionary measures and related views.

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

Survey date

:

2-4 October 2018

Survey method

:

Random telephone survey conducted by real interviewers

Target population

:

Cantonese-speaking Hong Kong residents aged 18 or above

Sampling method

:

Telephone numbers were 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 were then eliminated according to computer and manual dialing records to produce the final sample. For the landline samples, if more than one eligible subject had been available, the one who had his/her birthday next was selected.

Sample size

:

1,018 (including 672 landline and 346 mobile samples)

Effective response rate

:

53.0%

Standard error

:

Less than 1.6% (i.e. at 95% confidence level, the maximum sampling error of all percentages should be no more than +/-3.1%)

Weighting method

:

The raw data collected has been rim-weighted according to the latest figures obtained from the Census and Statistics Department regarding the gender, age, educational attainment (highest level attended) and economic activity status distribution of the Hong Kong population aged 18 or above.


Research Design

This was a random telephone survey conducted by interviewers under close supervision. To minimize sampling bias, telephone numbers were 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 were then eliminated according to computer and manual dialing records to produce the final sample. For the landline samples, when telephone contact was successfully established with a target household, if more than one subject had been available, selection was made using the “next birthday rule” which selected the person who had his/her birthday next.


The target population of this survey was Cantonese-speaking Hong Kong residents aged 18 or above. Telephone interviews were conducted during the period of 2-4 October, 2018. A total of 1,018 Hong Kong residents of age 18 or above were successfully interviewed, including 672 landline and 346 mobile numbers. The effective response rate of this survey was 53.0%, and the standard sampling error for percentages based on this sample was less than 1.6 percentage points. In other words, the sampling error for all percentages using the total sample was less than plus/minus 3.1 percentage points at 95% confidence level.

 

To ensure representativeness of the findings, the raw data collected has been rim-weighted according to the latest figures obtained from the Census and Statistics Department regarding the gender, age, educational attainment (highest level attended) and economic activity status distribution of the Hong Kong population aged 18 or above. The gender-age distribution of the Hong Kong population came from “Mid-year population for 2017”, while the educational attainment (highest level attended) distribution and economic activity status distribution came from “Women and Men in Hong Kong - Key Statistics (2018 Edition)”.
