2,087,285 postcode searches


This is no time to rest, there’s interminable media analysis of the Hartlepool by-election to catch up on.

So, how did we do?

As we announced yesterday, this year we had the best data coverage ever on the polling station finder. With 90% of councils sending us data, we were able to provide a polling station address to a higher proportion of postcode searches than ever before. Here are the stats!

πŸ“ˆ Number go up πŸ“ˆ

Between midnight on Monday morning and 10pm Thursday evening, our database processed 2,087,285 postcode searches. This includes searches received via the website of the Electoral Commission and other partners. Half of these searches occurred on polling day itself.

For comparison, both the 2019 local and EU elections saw around one million searches each, so we’ve effectively doubled our userbase.

The vast majority of these searches were via our API, because the social media giants linked to the Electoral Commission website rather than This meant that, for the first time ever, experienced far more users than its sister website. WDIV saw 377,000 users this week, compared with 650,000 for WCIVF.

In terms of data quality, we were able to show a polling station for 1,815,987 searches (87% of searches). This is consistent with our coverage of 336 local authorities (90.5%).

We’ll have a full analysis in our report in a few weeks’ time.
