Which format you want has nothing to do with the data type; DATEs can be entered or displayed in virtually any format you wish. I've said it, and the 2 earlier replies said it, but this is important enough to repeat: Always use the DATE datatype for information about dates.
The only exception is when fractions of a second are significant, or when you need to capture time zone information along with the date. In that case, use the TIMESTAMP data type, but DATEs are a lot easier to use, and there are many more useful built-in functions for manipulating DATEs, so use DATEs whenever possible. For date-of-birth, you probably don't want to record hours, minutes or seconds, let alone fractions of a second, so there's no reason to use a TIMESTAMP, and there is never any reason to use any other datatype, such as VARCHAR2 or NUMBER.
