Table 1. Survey Methods

Take the 2007 survey as an example. It was carried out between November 25 and December 10, 2007. It was conducted by using a computer-assisted telephone interviewing (CATI) system, targeted at regular residents aged between 6 and 84 years old who speak Chinese (including Cantonese, Mandarin and other dialects) and live in Macao with a residential telephone line.

In the 2007 survey, a random sample of 1,951 residents was successfully interviewed. The sample size yields a sampling error of ±2.3% at the 95% confidence level. Calculated by the Response Rate Formulae 3 (RR3) and Cooperation Rate Formulae 3 (CR3) of the American Association for Public Opinion Research (AAPOR, 2000), the response rate is 36.6% and the cooperation rate is 55.5%. Prior to formal analysis, the data were weighted against the latest Macao Population Census Estimates, in terms of cross-distribution of age and gender.
