Excavating LGBTQ+ lives in the birth cohort: an exploration of pen portraits and data storytelling.

Abstract

Birth cohort studies provide invaluable data on topics across the lifecourse, including health, education, socioeconomic conditions, and well-being. As a result, they are an important resource for biosocial researchers to answer numerous complex research questions. However, despite being positioned as representative of their national or regional context, cohort studies often fail to capture the experience of marginalised groups.One such group is sexual and gender minority (or LGBTQ+) people who, until very recently, have been largely invisible in birth cohorts. This is despite huge social and attitudinal changes in the last fifty years and clear evidence of the social, political, economic, and health and well-being disparities experienced compared to heterosexual cisgender people. However, due to small numbers, opportunities for quantitative analysis are limited and result in the neglect of LGBTQ+ data even when it is captured.This article presents a brief overview of how queer lives have (and have not) been captured by standard data collection and analysis techniques in the British birth cohort studies. Then, using a cohort born in 1970, the authors explore the possibilities of person-centred mixed-method pen portraits to improve understanding of this group's life trajectories.
