As of 2014, approximately one billion adults or ~22% of the population of the world have hypertension. It is slightly more frequent in men, in those of low socioeconomic status, and prevalence increases with age. It is common in high, medium and low income countries. The prevalence of raised blood pressure is highest in Africa, (30% for both sexes) and lowest in the WHO Region of the Americas (18% for both sexes). Rates also vary markedly within WHO regions with rates as low as 3.4% (men) and 6.8% (women) in rural India and as high as 68.9% (men) and 72.5% (women) in Poland. In Europe hypertension occurs in about 30-45% of people as of 2013. In 1995 it was estimated that 43 million people (24% of the populations) in the United States had hypertension or were taking antihypertensive medication. By 2004 this had increased to 29% and further to 34% (76 million US adults) by 2006. African American adults in the United States have among the highest rates of hypertension in the world at 44%. It is also more common in Filipino Americans and less common in US whites and Mexican Americans.
