In the UK, the report also found that the number of children with a congenital disability rose from 9.5 per cent of the population to 10.4 per cent in 2018.
That is a 6 per cent increase, with the rate increasing fivefold in Spain.
The number of UK children with an intellectual disability rose by 12 per cent, from 1.9 per cent to 3.5 percent.
In Ireland, the number with a physical disability rose more than fivefold from 1 per cent (1.6 per cent) to 2.4 (2.8 per cent).
Ireland’s rate of growth in the age group with a mental disability has remained relatively stable at just under 1 per 1,000, while in the UK it has increased by 1.4 percentage points.
The report also pointed to the rising number of disabled people in the country.
The proportion of disabled children has increased from just over 3 per cent a decade ago to 6.5-7 per cent today.
In the decade to 2020, the proportion of children under the age of five with a diagnosis of a physical or intellectual disability jumped from 6.1 per cent before the recession to 10 per cent.
It is the most significant increase in a decade, according to the report.
“The figures suggest that as we get older, we are more likely to get a disability diagnosis than in previous decades,” said the report’s co-author, Dr J. Craig Williams, an associate professor of clinical psychology at University College London.
“There is now a greater proportion of the adult population that is a disability sufferer.”
What is a congenitally disabled child?
It is a condition where a person has a physical impairment, but not a mental impairment, that causes physical limitations or impairments of the body.
The conditions can be congenital, acquired or acquired at birth, but they are often not.
They can also be diagnosed with an emotional or developmental disability, including Asperger syndrome.
The condition is often linked to autism, intellectual disability, learning difficulties and intellectual impairment.
It can also cause behavioural problems such as social distancing or aggression.
The prevalence of a condition in the United Kingdom was estimated at 1.1 in every 1,600 people, a rate that was lower than that of the US and higher than in other developed countries.
In 2020, almost half of all children with congenital disabilities in the world lived in the US, but the rate for children with intellectual disabilities was just over half, at less than 1 in every 3,000.
In 2018, children with the most disabilities lived in Japan, followed by Canada, France, Spain, Italy and the UK.
What does this mean for future research?
The UK is now in a position to lead the way in tackling this new and pressing disability pandemic.
“I think it is important that the UK continues to have a very high level of public health investment in mental health and other disability programmes, and I think that we are well on our way,” said Williams.
“In 2020, we were also the first country to pass a universal child benefit.
I think we have a strong commitment to mental health, and we are doing that with the funding we have available.”
Williams also highlighted the need for better mental health care.
“We have a lot of people that need to be better treated, so I think it’s a really good time for the UK to look at how to better support mental health in the population.”
He said it was important to work with all levels of society to improve the quality of care.
