A female crash test dummy introduced in the early 2000s represents a 5th-percentile woman (under 5 feet tall and 108 pounds) and was designed as a smaller-scaled version of the male dummy without accounting for sex-specific biomechanical differences such as muscle strength, fat distribution, and bone density.
