There is a higher incidence of ICH in patients of Asian ethnicity compared with those of other ethnic backgrounds. In terms of racial predilection, a higher incidence of ICH has been noted in Chinese, Japanese, and other Asian populations, possibly due to environmental factors and/or genetic factors.

Other factors associated with increased incidence of ICH include older age and male sex. US data suggest that the annual rate of ICH is approximately 12-15 per 100,000 individuals (approximately 40,000 cases per year), with 350 hypertensive hemorrhages per 100,000 elderly individuals.

Regarding income, there is a higher incidence of ICH in low- and middle-income countries (eg, Sub-Saharan Africa, Central Asia, and Southeast Asia).

Broadly, there is a higher incidence of ICH in black and Hispanic patients compared with white patients, due in part to the higher frequency of hypertension in these populations.
