The fly in the ointment for any social scientific research using Twitter data is that we do not know who tweets.
Twitter does not require users to publish demographic information such as gender, age, location, occupation. This lack of data on who is represented on the social media platform makes it difficult for researchers to explore how social phenomenon manifest online in relation to demographic characteristics.
In this webinar Luke Sloan, Senior Lecturer at Cardiff University and Co-Director of Cardiff Q-Step, will explore demographic representation on Twitter. He will discuss recently developed methods for deriving demographic proxies from Twitter metadata for age, sex and social class and for comparing the characteristics of UK Twitter users with Census data on the UK population.
