Abstract. Most copyrighted personality inventories facilitate norm-referencing through illustrative tables, yet their application to the many fields relevant to personality measurement is constrained by the need for stakeholders to possess the requisite financial resources to access them. Using an IPIP-NEO-300 dataset from Johnson’s IPIP-NEO data repository, we created open-source norm tables for different age groups (14–17 years; 18–25 years; and 30+ years) within a combined standardization sample from the United Kingdom (UK) and Ireland ( N = 18,591). The newly created tables are freely available online ( https://osf.io/tbmh5 ), and there is no need to ask for permission to modify them. We provide general instructions that can be used to create open-source personality trait norms for other countries, settings, and age groups, as well as gender-specific norms. There is great potential for these norms to be used in various settings and their open-source freedoms may encourage future collaborations and investigations.
