You don't own an umbrella, your formal wear is all fleece and you have free range chickens in your backyard, but you moved to Portland from Cincinnati last year. Are you really an Oregonian?

We on The Oregonian/OregonLive's Trending Team have been wrestling with this question for months. Who is a "real" Oregonian? How long do you have to live here before you can assume the title?

Sometimes a person's state-based identity is obvious: Some of us were born here and have lived here our whole lives and are clearly Oregonians. Some of us just moved here and are clearly not.

But there are gray areas too. Is the man who has lived here 30 years but was born in Kansas an Oregonian? What about the woman who was born here but lived in California for many years and still hasn't replaced her California driver's license with an Oregon one? Of course the commenters have opinions, but how can we know for sure?

So we created a scientific formula, very scientific, and tested it out and refined it until we had the exact perfectly weighted questions to determine the answer. All you have to do is put in your age, answer a several easy questions, and you too can know whether or not you are true Oregonian.

Methodology: While the concept of state-based identity is clearly nebulous, we decided on several important factors. The percentage of your life that you have lived in Oregon is important, not the actual number of years, as is how you self-identify. If you pronounce the name of the state wrong, that is also going to set you way back.

The most important thing though, is that even if you aren't officially an Oregonian yet, you can easily become one! And guess what, you never have to identify as an Oregonian if you don't want to. We still love you and want you here, wherever you're from!
