This dataset contains supplementary materials for the article "Imposed Coexistence: A Multidimensional Environmental Justice Analysis of Human-Elephant Conflict in Kuiburi, Thailand" published in People and Nature. Contents: (1) Semi-structured interview guide with 27 bilingual English/Thai questions used during fieldwork with 40 community members in Ruam Thai Village adjacent to Kuiburi National Park; (2) Thai-English environmental justice coding lexicon documenting how participant terminology mapped to five environmental justice dimensions; (3) Complete R code implementing TF-IDF vectorization, cosine similarity clustering, permutation testing (1,000 iterations), and network centrality analysis; (4) Statistical outputs including dimensional co-occurrence results with z-scores and p-values for all 10 dimensional pairs; (5) Participant demographics; (6) Sensitivity analysis across cosine similarity thresholds (0.80, 0.85, 0.90). Interview transcripts are not included due to deductive disclosure risk in a small community (738 households) where standard anonymization cannot prevent identification. All quantitative claims are fully verifiable through the provided statistical outputs.
