Collective term for race, gender, age, religion, income class, etc

I'm writing an article for a political website about the major traits that make an individual what he or she is (in terms of wealth, human rights, oppression or lack thereof, etc.). They include inherited traits (e.g. race, gender and age) and traits that may be acquired or modified later (e.g. religion, income class, etc.).

I just wondered if anyone knows of a collective term for such traits. I coined the term lifetags, but I wondered if there's an appropriate word that already exists.

Such terms are often associated with censuses, surveys and sociological/demographic studies, but I can't think of a word that describes them. Feel free to coin a new term; I want to enrich my vocabulary. ;)

Traits of the kind that you mention can be classed as demographic characteristics or demographic features.

According to the definitions supplied by Oxforddictionaries.com, demography has two denotations:

1 The study of statistics such as births, deaths, income, or the incidence of disease, which illustrate the changing structure of human populations.

1.1 The composition of a particular human population.

Discriminant is one word that I can think of. Though it has a mathematical meaning, there is also a meaning in the sense of language.

http://www.yourdictionary.com/discriminant - which cites 'The definition of a discriminant is some distinguishing characteristic or feature that allows someone or something to be separated from others.'

Intersectionality-the interconnected nature of social categorizations such as race, class, and gender as they apply to a given individual or group, regarded as creating overlapping and interdependent systems of discrimination or disadvantage
