Tracking global animal welfare progress requires robust metrics and baselines across species, sectors, and regions to guide effective advocacy.
Measuring welfare progress is essential to determining whether advocacy and policy are producing real outcomes for animals. Without robust metrics, efforts may continue despite producing minimal improvement. The shift from input-based measures (cage size) to outcome-based welfare assessment (behavioral indicators, health outcomes) represents an important maturation of the field. Global progress is real but uneven, with massive gaps remaining particularly for fish, invertebrates, and animals in low-income countries.
