Social Security says it's ending a major practice called unfair by critics. Here's what to know.

The Social Security Administration on Monday said it is making a major change that could help more people qualify for disability benefits. 

The change involves a practice used by the program to determine whether a disability applicant could, in fact, find another job based on their abilities, which could result in a rejection of benefits.

To make that determination, the SSA relies on a jobs database to suss out if there are any jobs the applicant can still perform. But critics have called the database unfair and flawed, given that it was last updated in 1977 and includes dozens obsolete occupations.
