Final answer:
While it's challenging to provide an exact number, a significant portion of the UK population likely has a relative on the autistic spectrum, as current estimates indicate that one in 88 children will develop ASD.
Step-by-step explanation:
Estimating how many people in the UK have a relative on the autistic spectrum is challenging, as Autism Spectrum Disorder (ASD) can manifest with varying degrees of severity, and the presence of the condition in a family can be widespread. Current research suggests that about one in 88 children will develop ASD, which is more prevalent in males than females, being four times more likely to be found in males. Considering this, and the fact that each child has multiple relatives, it's likely that a significant portion of the UK population has a relative on the autistic spectrum. However, without specific epidemiological data for relatives of autistic individuals in the UK, a precise number cannot be determined.
It is difficult to determine the exact number of people in the UK who have a relative on the autistic spectrum. However, it is estimated that 1 in 88 children develop autism spectrum disorder (ASD). ASD is four times more prevalent in males than females. Therefore, it can be inferred that a significant number of people in the UK have a relative on the autistic spectrum.
