This best-selling text continues to offer a comprehensive introduction to the field of social work with a unique focus on the diverse groups to whom social workers provide services; including children, older adults, disabled persons, and members of minority racial and ethnic groups. It covers the emergence of the profession of social work, career oportunities for social workers, and the values and competencies required of social workers. Timely issues that this edition addresses include the following: the events of 9/11 and their dramatic influence on human services in the United States; the United States involvement in Middle East warfare; the physical and emotional damage to individuals involved in Middle East warfare; and the 2000 Census---how substantial changes in the U.S. population suggest a need for realignment of social services.
