Where you live affects your credit worthiness.
Illegal, and radioactively so. The practice was called redlining and a bank engaging in it would have hellfire rained upon it.
Marital status affects your credit worthiness.
Also illegal.
The degree and school you attended affects your credit worthiness.
Untrue; credit reports don't include this information. (It is available from specialized vendors for doing things like e.g. verifying resumes, but banks don't habitually employ them because your credit history is much, much more reliable.)
The title of your job affects your credit worthiness.
Untrue; titles are generally not reported to CRAs, difficult to get out of customers, and difficult to verify. If you wanted to use them in underwriting, for the same amount of effort you can just ask "What is your salary?" and verify it with the employer the same way you'd verify their title; this gets you everything you want in a more reliable fashion, since salary inflation is less common than title inflation.
