Despite the convenience and low cost offered by online surveys, there are many occasions when face-to-face interviews are a far more effective option. Worldwide, there are still some 3.5 billion people who aren’t connected online, whose opinions will not be collected via online surveys. Even in areas of high internet connectivity, face-to-face interviews remain unbeatably the best method for systematically collecting responses from specific streets and neighborhoods. Alongside all this, the additional layer of personal contact means survey data can be enhanced by capturing subtle nuances in the environment and respondents’ reactions. While the advantages of face-to-face interviewing remain largely unchanged, the advent of CAPI as a fieldwork tool upgrades the traditional PAPI method with all the benefits of the digital age.
