I am a person of Armenian heritage (100%) and I am semi-fluent in the armenian language. In 1915 a genocide killed 1.5 million of us. Today there is only about 10 million Armenians left in the world. Armenia was the first country to adopt Christianity as its main religion. Does this mean that a person of Armenian heritage is a URM. I have seen this as an ethnic background option for a private high school application. I am wondering whether Harvard, MIT, or Columbia would see an Armenian person as a URM.
I am not aware of any college that treats those of Armenian descent as underrepresented minorities. Those included in the URM group typically are African Americans, Native Americans (American Indians and Native Alaskans and Hawaiians), Hispansics of Mexican and Puerto Rican descent, and, for many engineering programs, women.
No Armenian is not an URM. They are actually caucasians in the literal sense. However you might be able to put together a nice essay about your heritage.
