We cannot order Social Security numbers in any meaningful way. Some people have Social Security numbers that start with a higher number than others but there is no meaningful difference signified by this.

On the other hand, interval level variables are ordered.
But you are allowed to subtract disability-related expenses from your wages before measuring it against SGA. As an example, Social Security may allow you to deduct the cost of a taxi from your monthly earnings if you must take a taxi to get to and from work because of your disability.

Social Security's Trial Work Period consists of nine months (not necessarily consecutive) in which you work and can earn any amount of money.
