Polls as accurate as they have ever been, study says | Politics | The Guardian

Polls as accurate as they have ever been, study says | Politics | The Guardian:
Looking at polls for the last week of campaigns for 220 national elections in 32 countries over the decades to 2017 – with data for a handful of countries stretching back to 1942 – errors have held steady at about 2%. When the team looked only at the 11 countries that had regular polling over several decades, polling errors were found to have dropped over time.
