Ancestry Atlas addresses the significant lack of discussion afforded to actual methodologies employed when measuring cultural diversity, even though there is an abundance of academic literature addressing the importance of cultural diversity The objective of our study was to develop of a set of quantifiable dimensions of diversity that can be benchmarked, compared over time, evaluated against adjustable variables, and used to provide recommendations. Our research began with a literature review to assess existing models for measuring diversity, which helped us identify gaps in methodology and formed the background for a model of measurement that allows for the quantification of three key parameters that constitute cultural diversity: ethnicity, language, and belief (worldviews). This model was used in the creation of a mathematical formula that generates a ‘diversity index’ based on the value of each parameter within a particular community or group. ‘The diversity index has been developed for implementation in a digital tool called Ancestry Atlas that provides visual insights to the diversity of particular groups. Ancestry Atlas collects user-submitted data that is then translated into visual insights to organisation’s linguistic, national, and gender composition, and provides them with their own diversity index. Ancestry Atlas’ use in Australian organisations is supplemented by lesson plans, teacher resources and guides in interpreting and discussing results with students. Organisations using Ancestry Atlas have access to consultants who work with clients to create strategic recommendations for cultural competence, diversity and inclusion strategies, and to better understand contemporary markets.
