Presented in the form of 30 tables are statistics on blindness in 16 states which have agreed to uniform definitions and procedures to improve reliability of data regarding blind persons. The data indicates that rates of blindness were generally higher for nonwhites than for whites with the ratio ranging from almost 10 for glaucoma to minimal for "other retinal desease", and that nonwhite females were most likely to become blind due to optic nerve disease. Presented in tables are data concerning trends, additions to registers in 1969 and 1970, first additions to registers, cause of blindness for first additions to registers as determined by physicians, removals from registers, demographic information on persons on registers, estimated midyear population, simplified cause of blindness for all additions to registers, and simplified cause of blindness for all persons on registers.
