This study examines characteristics of Hispanic females in single- and dual-headed households in an effort to understand the impact of the feminization of poverty on Hispanic Americans of Mexican, Cuban, and Puerto Rican origin. The following aspects of these women are examined: (1) sociodemographic characteristics; (2) language of interview; (3) education level; (4) income level; (5) federal aid receipt; and (6) health characteristics. Results indicate that women from single-headed households were more likely to be middle-aged, and more likely to be divorced or separated rather than widowed or never married. No significant differences were found between the two groups with regard to language of interview or education level. Mexican American single female heads of household were more likely to live in poverty than were females of dual-headed households. Results reveal that almost two-thirds of all Mexican American female-headed households have incomes below the federal poverty level. In spite of these findings, few single females were receiving Aid to Families with Dependent Children, but more than half had received food stamps in the 12 months prior to the interview. Single-female headed households were much less likely to have private health insurance. Single female heads of household indicated that they encountered barriers to health care. Fifteen figures and 12 references are included. (JS)
