The dataset contains all the data collected by the author for a research project on personal finance among Hong Kong young gay men, titled "Too Gay to Save? Personal Finance Among Hong Kong Young Gay Men at the Intersection of Class and Sexuality". The study is qualitative in nature, drawing primarily on in-depth interviews from 30 Hong Kong young gay men aged between 18 and 35 (M = 29.0). The dataset contains two sets of data, namely (1) verbatim transcripts of the 30 in-depth interviews conducted by the researcher with the respondents between June and August 2023, and (2) post-interview questionnaires completed by the respondents, which serve mainly as supplementary materials for qualitative data analysis in the thesis.
