The denominator used for the prevalence of diagnosed HIV (from SOPHID) was the estimated population mid-year provided by the Office of National Statistics.
The denominator used for the prevalence of HIV recorded (GPRD) was the number of patients registered mid-year.
Due to old geography codes and poor quality of the data in 1995, prevalence by region is not shown for this year.
