Average income is a strange concept when talking about a full range of ages and across the geographic spectrum as mentioned by several people above.  Many people in their twenties and slightly older are supporting at least one other person on their average income, often a child.  An income that might be sufficient for one person can be a real challenge for two or more. Here in the States I notice that young people do not always realize that the income that is okay for now will not be okay for later.  Because of that lack of foresight they don't plan ahead for an adequate income for a family.  This experiment is going to be interesting to watch, but knowing you and your background, I expect that you will ace this as creatively as you do most things. Keep us posted.
