looking at people's credit from all over the country, I have noticed that, generally, it seems in certain areas, people tend to have lower or higher scores. Of course there are always exceptions.
As for how credit scores are figured, there is a system. I know most of this (because I deal with it so often), but it is easier to copy/paste. This is from
www.myfico.com (I abbreviated it a bit).
How is my score calculated?
-35% affects Payment History. Meaning any lates; collections; charge offs; bankruptcies; judgments; liens or the such will hurt the score. All is time based, the older the information the less it is contributing to the scores.
-30% affects Utilization. It is best to have several accounts with low balances distributed then it is to have fewer accounts maxed out.
-15% affects Established History. The longer you maintain open accounts with creditors the better.
-10% affects Inquiries. Don't apply for credit unless you know you can get it or that you need to get it; unnecessary credit inquiries are going to hurt the scores - especially if your over all credit file is small to begin with.
*Mortgage & Auto industry has special rules for inquiries: all applications for credit resulting in pulled credit reports within a 14 day period of time will only count as one inquiry & will be suppressed from affecting credit scores for 30 days. So if you plan to go shopping for a mortgage or a car, do your research first picking what companies you want to apply with and do this all within a 2 week period of time so that the scores are not affected too much.
-10% affects Mix of Credit. Use different types of credit (revolving; installment; auto; mortgage...) evenly.
