4.3.3 Multi-stage Sampling Procedure

Generally, it is very difficult to use random sampling method in Hong Kong due to some reasons such as the problem to get a full list of citizens. As for Hong Kong, it consists of 18 District Council districts, which are scattered in Hong Kong Island, Kowloon and New Territories. Considering the availability of resource and energy, a multi-stage sampling method was adopted.

In this survey, a three-stage sampling method was implemented. It should be noted that the three-stage sampling method could not generate a probability sample. Thus, a randomization was only used in the first stage to select districts. In the following stages, a convenient sampling was employed. In the first stage, a total of 18 districts were taken as the primary units for sampling. All the target population cases in each district were listed, together with the accumulative cases (see Table 4.2). To obtain a sample which could represent the characteristics of Hong Kong to a large extent, one third of the districts, that is, six districts were selected after balancing the restriction of finance and energy. Six random figures were chosen from Random Integer Generator. Then six districts were randomly determined, they were Sha Tin, Kwai Tsing, Sham Shui Po, Wai Chai, Kowloon City (repeated for the second time). In the second stage, all the DECCs in each of the selected districts were listed as the secondary sampling unit. After coordinating with the DECCs, invitation letter stating the survey purpose and procedures was mailed to each and every DECC of the six selected districts. The DECC which first approved the study request in each district was chosen as the site of study. Consequently, the six DECCs were Ma On Shan DECC (Sha Tin), SAGE Chan Tseng Hsi DECC (Kwai Tsing), Ho Kin DECC (Sham Shui Po), St James Settlement DECC (Wan Chai), Holy Carpenter Church DECC (Kowloon City), and Lok Man Alice Kwok Integrated Service Center (Kowloon City). In the third stage, invitation letters were distributed to all center members of the chosen DECC and the first 68 members who gave consent to participate in this survey were invited to the interview at the center on an appointed day.Table 4.2Distribution of population aged 65 or above in Hong Kong
