We find out why poll predictions sometimes get it wrong.

2024 is a huge year for elections, with more than 60 countries holding national elections and over half the world鈥檚 population voting. With each election it can seem like opinion polls dominate the coverage but how are these polls carried out? We speak to pollster and data analyst David Byler from the American non-partisan polling company Noble Predictive Insights about how it all works.

We also hear from the 成人快手鈥檚 North America correspondent Anthony Zurcher, who explains how significant the polls are in the 2024 US Presidential election between Kamala Harris and Donald Trump.
