Asia: Polling and Politics

Several Asian democracies — including Japan, South Korea, Taiwan, India, Indonesia, the Philippines and Thailand — hold regular competitive national elections, with sophisticated political polling industries operating in most of them. The methodological challenges, however, are considerable. Population sizes can run into the hundreds of millions, ethnic and linguistic diversity makes representative sampling expensive, and coverage gaps in mobile and internet penetration vary sharply by country and demographic. The best Asian polling firms have responded with mixed-mode designs, in-person sampling in hard-to-reach regions, and increasingly sophisticated weighting.

Electoral systems vary just as widely. India and the United Kingdom-derived systems in the region use First Past the Post in single-member constituencies. Japan uses a mixed system with both single-member and proportional list components. South Korea has a comparable hybrid. Taiwan combines single-member constituencies with a small proportional top-up. Each of these systems implies a different relationship between vote share and seat share, and each requires the careful reader to think through how a polling number actually translates into political outcomes.

Coalition politics is the norm in most Asian parliamentary democracies. Stable two-party competition is rare; alliances of multiple parties, sometimes formed before the election and sometimes after, dominate government formation. As in Europe, the question of who is on which side of which alliance is often more important than the polling number for any individual party.
