The number of people with a stake in the issue is going to mount. I am not saying that there will be a true increase in the prevalence of autism. As we saw in chapter 3, it is unclear how much of the apparent change involves awareness and diagnostic standards. Even if there has been a true increase in recent decades, there is no way of knowing whether it will go on. But the rise in the number of autism diagnoses and educational determinations will translate into a growing population of people who have lived with the autism label, and who think of themselves as autistic. Most in this category will have family members and other people who are close to them. They may be guardians or caregivers, or they may just be friends and relatives with a deep concern. Either way, autism will be part of their lives, too. Overall, the share of Americans who know someone with autism will surely top the 39 percent recorded in 2008. One study found that 60 percent of respondents in Northern Ireland knew someone with autism in their own family, circle of friends or co-workers. There is no reason to think that the figure would be lower in the United States.
