Occurrence

Research published in 2016 indicated that up to two percent of British fathers unknowingly raise a child who is the biological child of another man.

A 2005 scientific review of international published studies of paternal discrepancy found a range in incidence, around the world, from 0.8% to 30% (median 3.7%). However, as many of the studies were conducted between the 1950s and the 1980s, numbers may be unreliable due to the inaccuracies of genetic testing methods and procedures used at the time. One study, which published a rate near 30%, was performed on populations in which the purported father already suspected that he was not the genetic parent, rather than on a fully random population. Studies ranging in date from 1991 to 1999 quote the following incidence rates: 11.8% (Mexico), 4.0% (Canada), 2.8% (France), 1.4% and 1.6% (UK), and 0.8% (Switzerland). These numbers suggest that the widely quoted and unsubstantiated figure of 10% of non-paternal events is an overestimate. However, in studies that solely looked at couples who obtained paternity testing because paternity was being disputed, there are higher levels: an incidence of 17% to 33% (median of 26.9%). Most at risk were those born to younger parents, to unmarried couples and those of lower socio-economic status, or from certain cultural groups.

A 2008 study in the United Kingdom found that biological fathers were misidentified in 0.2% (1 in 500) of the cases processed by the Child Support Agency. Of that 0.2%, those resolved with DNA paternity testing between 2004 and 2008 showed that between 10 and 19% of mothers had misidentified the biological father; data about why mothers identified the wrong biological father were not available.
