====Prevalence====
Older people are much more likely to carry face mites; about a third of children and young adults, half of adults, and two-thirds of elderly people carry them.<ref>{{cite journal |first1=H.

W. |last2=Hauswirth |date=1986 |title=Prevalence of hair follicle mites, ''Demodex folliculorum'' and ''D. brevis'' (Acari: Demodicidae), in a selected human population in western New York, USA |journal=[[Journal of Medical Entomology]] |volume=23 |issue=4 |pages=384–388 |pmid=3735343 |doi=10.1093/jmedent/23.4.384}}</ref> The lower rate in children may be because children produce less [[sebum]], or simply have had less time to acquire the mite. A 2014 study of 29 people in North Carolina, USA, found that all of the adults (19) carried mites, and that 70% of those under 18 years of age carried mites.<ref name=Thoemmes>{{cite journal |last1=Thoemmes |first1=Megan S. |last2=Fergus |first2=Daniel J. |last3=Urban |first3=Julie |last4=Trautwein |first4=Michelle |last5=Dunn |first5=Robert R. |last6=Kolokotronis |first6=Sergios-Orestis |title=Ubiquity and Diversity of Human-Associated ''Demodex'' Mites| journal=[[PLoS ONE]] |date=27 August 2014 |volume=9 |issue=8 |pages=e106265 |doi=10.1371/journal.pone.0106265 |pmid=25162399 |pmc=4146604|bibcode=2014PLoSO...9j6265T |doi-access=free }}</ref> This study (using a DNA-detection method, more sensitive than traditional sampling and observation by microscope), along with several studies of cadavers, suggests that previous work might have underestimated the mites' prevalence. The small sample size and small geographical area involved prevent drawing broad conclusions from these data.
