A significant trend over time has been observed in the racial distribution of persons in the Model System database.
Among persons injured between 1973 and 1978, 77.5% of persons in the database were Caucasian, 13.5% were African-American, 5.7% were Hispanic, 2% were American Indian and 0.8% were Asian.
However, among those injured since 1990 only 59.1% were Caucasian, while 27.6% were African-American, 7.7% were Hispanic, 0.4% were American Indian, 2.1% were Asian (and 0.5% were unknown and 2.5% were unclassified).
