There is listerature indicatingn disability identification has increased since Covid, and Long Covid is now recognized by the ADA as a disability.
There's also been increases in rates of diagnosis for many conditions, including autism, due to better screening and availablity of screening services. Autism is now diagnosed at a rate of 1 in 36 children. Diagnoses of genetic disorders resulting in developmental disabilities beyond the typically heard of diagnoses have increased in as whole exome sequencing has become more widely/readily covered by insurances.
1 in 4 adults have some type of disability.
The increases in disability identification should be resulting in more proactive planning by society in general, but that doesn't appear to be the case, and isn't likely to change any time soon.
