← What's Up In

Coverage and accuracy

How much each city holds, how fresh it is, and how it measures up when we check it against the sources and the live listings. Every event on every city site links to its original listing.

119,522 upcoming events across 10 cities. Each city’s own page lists its sources, freshness and audit details.

Per city. Recall = share of events the sources themselves list that we hold (sources we can re-read in full). Accuracy = share of sampled events whose original listing was live and matched.
