Cost of living is kind of a wash in a lot of ways. Housing is cheaper in Oklahoma, but Maryland is actually cheap compared to other Northeastern areas, which isn't bad for it being the wealthiest state in the country (most of said wealth being concentrated in the counties near DC, of course). As far as gas, Oklahoma has the cheapest gas in the US by quite a margin, but since I did a lot more driving in Oklahoma than I'm doing in Maryland thanks to Baltimore being less sprawling than Oklahoma City/Norman, I spend less on gas in MD. Food is actually somewhat cheaper in Maryland. Oklahoma not only has one of the highest sales tax rates in the country - the state rate is 4.5%, but the cities and counties impose their own taxes and the actual sales tax rate ends up being 9-11% - but they also tax groceries, while Maryland exempts most groceries and has a 6% sales tax rate. The auto insurance was the one big case of sticker shock I've had since I came here. Oklahoma is actually one of the more expensive places to get auto insurance thanks mostly to the weather there - tornadoes and hail are a big source of claims in OK - but 15 years of being with the same State Farm agent plus a good driving record netted me a pretty low insurance premium there. My rates doubled when I came here. I found out later that Baltimore is one of the most expensive cities for auto insurance. Oh well.
