i live in an area much like New York i guess, or maybe North Dakota.. {37-thousand US Dollar per year}
i don't know if these are after-tax income figures, but i make about 1100 euros a month at the moment, i have 100 euros per week (US dollars well could be the 'New York' equivalent { the city i live in is a touristy city after all }) to spend on things like food and tobacco and going out (which really is not a whole lot in my humble opinion).
I'm not actually poor for my region, but i'm certainly below middle class in my current income level..
