CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -Boys are four times more likely to be diagnosed with autism than girls. Most children were still being diagnosed after age 4, though autism can be reliably diagnosed as early as age 2.

Detailed explanation-2: -Consistent with previous reports, boys were 4 to 5 times more likely to be identified with ASD than girls. The rate for ASD is 1 in 34 among boys (or 2.97 percent) and 1 in 145 among girls (or 0.69 percent).

Detailed explanation-3: -ASD occurs in all racial, ethnic, and socioeconomic groups. It is more than 4 times more common among boys than among girls.

Detailed explanation-4: -Conclusion: Of children meeting criteria for ASD, the true male-to-female ratio is not 4:1, as is often assumed; rather, it is closer to 3:1. There appears to be a diagnostic gender bias, meaning that girls who meet criteria for ASD are at disproportionate risk of not receiving a clinical diagnosis.
