The three main predictors of whether or not Americans are poor are their race or ethnicity, education level and gender (male or female).

Explanation:

The main predictors in a study that seeks to assess whether Americans are poor or not is race or ethnicity, education level and gender. These are the main predictors because they are the main influential on income inequality and entry into the labor market.

The existence of entrenched values in a given society that lead to discrimination on the basis of race, gender and level of education means that these characteristics exert influence in the labor market, both in admission to a particular type or employment relationship and in the definition of its remuneration. That is, people who have equal attributes, except for race, school level or gender, are valued differently by employers or service users, only by virtue of the latter attributes, characterizing the existence of prejudice that leads to direct discrimination . That is why the market pays more adequately to the white man with higher education diploma to the detriment of black and brown men, women and those with a low level of education.
