Some studies were descriptive, comparing health literacy prevalence across disparity conditions. Others showed that disparities in health literacy between disparity populations and majority populations contributed to differences in access and quality of care.

It is interesting to note, Cooper said, that health disparities research has evolved in a manner similar to health literacy research. They both began by describing problems in different populations, then moved into
