BBC Verify fact-checks Donald Trump's autism claims

Part of Other Side of the Story

BBC Verify is dedicated to examining the facts behind the stories you might see online and on your social feeds. They’ve looked at some of the claims the US President Donald Trump made recently about the rates of autism in the US, low autism rates in the Amish community and the effects of the combined MMR vaccine.

Check out the video below to see what he had to say and whether there’s any truth to the claims.

Donald Trumps claims on rates of autism in the US

US President Donald Trump spoke about the rise in autism in the US on Monday. But do his figures on the rate of autism really add up?

Trump said that autism rates have risen, from "one in 10,000…probably 18 years ago" to "one in 31" by 2025. That final statistic is correct according to the Center for Disease Control and Prevention, and this rate has increased compared with about 18 years ago, when it was 1 in 110 children. But this difference is nowhere near as large as Trump suggested.

Donald Trump's claims about low autism rates in the Amish community

Trump cited the Amish as a group within the US who have "virtually no autism" within their community.

BBC Verify say that there are far fewer opportunities to diagnose autism in the Amish community, which could explain the lower rates. Autism diagnosis often happens through mainstream school, whereas Amish children generally attend private schools in the community and most dropout at around 14 years old. There are also very few studies on autism in Amish communities.

Donald Trump's claims about MMR

Another claim made by Trump was around the effects of the mumps, measles and rubella (MMR) vaccine, suggesting that they should be taken separately rather than combined. There’s no evidence to support his claim.

According to UK government advice, giving separate MMR jabs would be experimental. It goes on to say that single vaccines would end up less safe than the combined MMR, because children would be left for extended periods of time without being immunised from the other diseases.
