A person or an organization is known by many identities. There are several categories under which they can be classified. One of them is the gender of a person. Other identities may contain their ethnicity, age, race, religion etc. It has grown to be an extremely complex procedure to classify a person into the various identities in the present times and is becoming even more difficult to do so with every passing day. The book 'Gender and Other Identities: Complex conceptualizations in the new age' outlines this complexity in detail and explains the reason behind each identity of classification.
