The Death of Polling?

39,928 views

Published on

The spotlight is on pollsters in the UK, following the performance of the polls at the 2015 General Election. Are we alone in facing this challenge, or is it a global issue? Does the experience in other countries point to what we should be doing in the UK?

Ipsos has many of the leading polling experts from around the world, and we brought them together in London to provide unique combined insight. Our panel members from the US, Canada, Italy and Sweden talked us through the role and challenges of polling in their countries and what we need to do to get it right. They also updated us on the political landscape of their countries, with outlines of the major elections they have recently had, and in the case of the US, the on-going race to the White House.
