Description:

People possess multiple identities, the relative salience of which responds dynamically to social context. Whether one thinks of oneself as a parent, an employee, a spouse, a particular gender, or an American varies from place to place and time to time. National identity in particular is a crucial master frame through which people understand their sense of collective belonging and their political choices. Yet, research on national identification has been limited to cross-sectional data, often gathered using single survey items, which fail to take into account the contextually of identity. With large-scale social media data a different approach is possible. Our study traces daily fluctuations in American identification using a random sample of U.S. Twitter/X users between 2012 and 2022. Because identifying tweets that engage with nationhood is akin to looking for a needle in a haystack, we employ few-shot classification using Llama 2, a large language model, combined with fine-tuning to further improve model performance. Our findings reveal that American identification rises and falls in a patterned manner, partly in response to nation-relevant events widely reported in the media. We show which events have the largest impact on nationalism time trends, estimate the collective half-life of identification events, and examine which events are politically galvanizing versus polarizing. In particular, we find that national identification gained chronic salience after 2016, when it first became a central point of contention in U.S. presidential elections.
