How to research cities through data?
A talk for Yandex.Q, streamed live on YouTube on August 29, 2022, for a general audience. The question I set out to answer: how do you actually study a city through data? I walked through the sources I reach for — social media traces, mobility, open municipal data — what each one can and can't tell you, and why reading a place through how people behave often beats reading it off a map.
