You might want to use "Hispanic" instead of "Chicano".
The Detroit Hispanic market is over about 50% of Mexican heritage or origin, but there is a significant percentage from Central America, South America and the Caribbean, particularly Puerto Ricans.
"Chicano" is a term that applies only to persons of Mexican heritage and tends to be applied, when used at all, to those born in the US who "don´t know Mexico". A similar term is "Pocho" which also applies to second generation Hispanics with Mexican parents.
Of the Hispanics I know who are of Mexican heritage, very few like to be called "Chicanos" as the term is dated to the 60's and does not represent them. I just asked a couple of people and the answer was, in various wordings, "I hate the term" and "I am offended when it is used towards me". One person said the term to him ha connotations related to militant groups of the late 20th Century.
