Deaths per million persons due to<unk>  in 2012. In 2017, the Global Burden of Disease Study estimated there were 1.1 million new cases, and in 2019 the World Health Organization (WHO) reported a total of 20 million cases globally.<unk>  affects around 0.3–0.7% of people at some point in their life. It occurs 1.4 times more frequently in males than females and typically appears earlier in men – the peak ages of onset are 25 years for males and 27 years for females. Onset in childhood, before the age of 13 can sometimes occur. Other reviews find no difference in the prevalence of<unk>  between the sexes. A later onset can occur between the ages of 40 and 60, known as late onset, and also after 60 known as very late onset. Worldwide,<unk>  is the most common psychotic disorder. The frequency of<unk>  varies across the world, within countries, and at the local and neighborhood level. This variation has been estimated to be fivefold. It causes approximately one percent of worldwide disability adjusted life years and resulted in 17,000 deaths in 2015. In 2000, WHO found the percentage of people affected and the number of new cases that develop each year is roughly similar around the world, with age-standardized prevalence per 100,000 ranging from 343 in Africa to 544 in Japan and Oceania for men, and from 378 in Africa to 527 in Southeastern Europe for women. About 1.1% of adults have<unk>  in the United States. However, in areas of conflict this figure can rise to between 4.0 and 6.5%.
