How many people had aspergers in 2000?

In 2000, specific prevalence rates for Asperger's syndrome were not well-established, as it was still a relatively newly recognized condition. Estimates suggested that about 0.3% to 0.7% of the population might have been affected, but these figures varied widely due to differences in diagnostic criteria and awareness. In 2013, the DSM-5 reclassified Asperger's syndrome under the umbrella of Autism Spectrum Disorder (ASD), making historical comparisons more complex. Thus, while exact numbers are unclear, the condition was recognized in a subset of the population.
