How does Gallup's global polling work?

Gallup conducts surveys worldwide to help world leaders better understand their citizens' attitudes, behaviors, and well-being. Gallup continuously surveys in more than 150 countries and areas on more than 100 global questions as well as region-specific items. Gallup's global surveys cover more than 98% of the world's adult population through representative samples.

Gallup interviews approximately 1,000 residents per country. The target population is the entire civilian, non-institutionalized population, aged 15 and older. Gallup asks everyone from Australia to Pakistan the same questions, every time, in the same way, with the same meaning, and asks them in his or her own language to produce statistically comparable results. Gallup uses telephone surveys in countries where telephone coverage represents at least 80% of the population. Where telephone penetration is less than 80%, Gallup uses face-to-face interviewing.
