Points to Note
The question used in all POP surveys on political figures, in general, is: "Please rate your support of [certain person] using a 0-100 scale. 0 stands for absolutely no support, 100 stands for absolute support, 50 stands for half-half. How would you rate [certain person]?". This is different from the hypothetical question of "Would you rote for a certain person if tomorrow is the voting day?" normally used in the West. Such hypothetical questions should only be applicable to generally elected political figures. POP has considered this point back in 1991 when we started this series of tracking questions
The monthly figures presented in the relevant tables and charts are calculated from average figures obtained in separate surveys conducted during a certain month, while the half-yearly figures are calculated from monthly averages. All of them are averages of averages.
