| 所有調查的訪問對象皆為十八歲或以上之操粵語的香港市民。 | ||
| 2014年1月中起，電話號碼抽樣方法是先從通訊事務管理局之香港電訊服務號碼計劃獲取已分配予電訊商的電話字頭，然後以隨機方式從中產生號碼。最後，按照電腦撥打及過往調查記錄，剔除無效號碼成為最終樣本。 | ||
| 2014年1月中或之前，電話號碼抽樣方法是從住宅電話簿中首先以隨機方法抽取「種籽」號碼，再以加一減一加二減二的方法產生另一組號碼，然後在混合後再過濾重覆號碼，再以隨機排列方式排次成為最後樣本。 | ||

Survey Method
 | Surveys on people's sense of ethnic identity are conducted annually every June since 1997. All surveys are conducted by telephone interviewers under close supervision. | ||
| Target population of these surveys are Cantonese speakers in Hong Kong of age 18 or above. | ||
| Starting from mid-January 2014, 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. | ||
| Before mid-January 2014, telephone numbers are first selected randomly from telephone directories as seed numbers. Another set of numbers is then generated by using the plus/minus one/two method. Duplicate numbers are then screened out, and the remaining numbers mixed in a random order to become the final sample. | ||
| Upon successful contact being made with a target household, one member of the household is selected among those present using the "next birthday" rule. | ||
