(CNN) -- Hispanics and Latinos are described as the largest minority group in the United States, as a burgeoning force in the electorate and as an untapped frontier of the business market. Yet these descriptions belie the complexity of the 44 million people to whom they refer.
Even the terms used to name them -- Hispanics, Hispanic-Americans, Latinos, Latino-Americans, the Spanish-surnamed -- too tightly package the people categorized by those definitions, some observers say.
"We are mixed and we are many things," said Phillip Rodriguez, a documentary filmmaker. Many of his films, such as "Los Angeles Now" and "Brown is the New Green: George Lopez and the American Dream," explore the experience and identity of Latinos in the United States.
Latinos "very often don't share language, don't share class circumstances, don't share education; it's very difficult to speak about them as one thing," he said.
From a census standpoint, being of Hispanic or Latino origin means a person identifies himself in one of four listed categories: Mexican, Puerto Rican, Cuban or "other Spanish, Hispanic or Latino" origin. In the latter more open-ended category, respondents can write in specific origins, such as Salvadoran, Argentinean or Dominican.
