Attitudes towards the term
Some intersex organizations reference "intersex people" and "intersex variations or traits" while others use more medicalized language such as "people with intersex conditions", or people "with intersex conditions or DSDs (differences of sex development)" and "children born with variations of sex anatomy". In May 2016, interACT published a statement recognizing "increasing general understanding and acceptance of the term intersex".Australian sociological research on 272 "people born with atypical sex characteristics", published in 2016, found that 60% of respondents used the term "intersex" to self-describe their sex characteristics, including people identifying themselves as intersex, describing themselves as having an intersex variation or, in smaller numbers, having an intersex condition. Respondents also commonly used diagnostic labels and referred to their sex chromosomes, with word choices depending on audience.Research on 202 respondents by the Lurie Childrens Hospital, Chicago, and the AIS-DSD Support Group (now known as InterConnect Support Group) published in 2017 found that 80% of Support Group respondents "strongly liked, liked or felt neutral about intersex" as a term, while caregivers were less supportive. The hospital reported that the use of the term "disorders of sex development" may negatively affect care.Another study by a group of childrens hospitals in the United States found that 53% of 133 parent and adolescent participants recruited at five clinics did not like the term "intersex". Participants who were members of support groups were more likely to dislike the term.
Medical terminology shifted in the early 21st century, not only due to concerns about language, but also a shift to understandings based on genetics.The Intersex Society of North America has stated that hermaphrodites should not be confused with intersex people and that using "hermaphrodite" to refer to intersex individuals is considered to be stigmatizing and misleading. Prevalence
Estimates of the number of people who are intersex vary, depending on which conditions are counted as intersex. The now-defunct Intersex Society of North America stated that:

If you ask experts at medical centers how often a child is born so noticeably atypical in terms of genitalia that a specialist in sex differentiation is called in, the number comes out to about 1 in 1500 to 1 in 2000 births [0.07–0.05%]. But a lot more people than that are born with subtler forms of sex anatomy variations, some of which wont show up until later in life. Anne Fausto-Sterling and her co-authors broadly said in 2000 that "[a]dding the estimates of all known causes of nondimorphic sexual development suggests that approximately 1.7% of all live births do not conform to a Platonic ideal of absolute sex chromosome, gonadal, genital, and hormonal dimorphism"; these publications have been widely quoted by intersex activists.
