Abused children live in families of all socioeconomic levels, races, nationalities, and religious groups, although child abuse is reported more frequently among families.

The correct answer is lower-class nonwhite.

Explanation:

The lower class is the poorest population segment of human society. It is characterized by having great gaps in its way of life and limitations in terms of access to economic resources. They are usually unemployed people, who do not own their own home or other goods or properties that are essential for living.

To this socioeconomic class belong people with very low educational levels, barely with primary education and some with secondary education. Some casual or independent workers also enter this class. Lower class families do not have good basic services in their homes.
