Why has autism rates remained the same since thimerosal has been eliminated from vaccines in 2001?

In brief: Autism
According to the cdc, no association between MMR and autism.
There was a theory that the thymersol preservative was contributing to autism, but the autism rates rose even after the thymersol was removed. It is a major mistake to not have one's kids fully vaccinated. The cause of autism is not known, although recent studied suggest a relationship with fever during pregnancy.

In brief: Easy
Because the chemical has nothing to with autism.

In brief: Because vaccines
With thimerisol don't cause autism.
There is a genetic set-up for autism, just like there is for diabetes & asthma. Unfortunately, there are many genetic set-ups for autism, epigenetic factors cause changes in function but not structure of fetal genes (e.g., some viruses & toxins).. Environmental triggers precipitate the symptoms of diabetes, asthma & probably autism, but the ? Is which ones.

In brief: They have increased
It is likely that disorders on the autism spectrum may differ in cause and in fact may really be many different diseases.
Within the last several years the autism rate has risen from 1/150 to 1/88. Mercury may be discovered to be a factor but now there is no definitive research to support it. Immunization causing autism was debunked because that research was flawed and results manipulated.

The recent research shows maternal prenatal mercury exposure may be implicated in a host of developmental disorders. Not childhood exposure.

In brief: Actually gone up
The rate of autism was about 1 case per 150 children in 2000, and is now 1 per 88 (in boys it's 1 in 54).
The inciting cause(s) is multifactorial as dr fricke stated. One single agent of etiology is not supported by research.

It has gone up.I sometimes wonder if the same epigenetic factors that grant the young their ease with technology have just gone awry in some
