Selected as a part of competitive UC Berkeley Data Discovery Research Programs, “Indigenous Brands & Social Movements”

  • Cleaned datasets of trademarks owned by Native American Tribes through eliminating unnecessary columns, filling NAs with 0 other values
  • Based on the cleaned datasets, visualized locations of the trademarks on maps through usage of data visualization tool called DataWrapper

Research Program Description

Have you noticed how many brands in the marketplace use indigenous/Native American – oriented terms and imagery? From the notorious Washington Team to the logo on Land of Lakes butter, indigenous imagery and appropriation is everywhere, and worthy of serious study and data analysis. This project aims to bring the work of social movements and activism to a data-intensive study of First Nations brands and trademarks in order to chart a path forward. In this project, we will study how many of these terms are owned by native vs. non-native entities, study how these brands have changed over time, and how the law might be better deployed to protect ownership of indigenously oriented trademarks, and encourage retiring marks that are considered offensive or appropriative.
