Individuals in the United States must be aware of the international dimensions of human services because

• A. Because 99% of the world's population growth occurs in developing countries
• B. Because international laws govern domestic practice
• C. Because all populations in the U.S. are immigrants
• D. Because U.S. policy is dictated by the UN

Answer: (A)

Global population growth concentrated in developing countries drives many trends that U.S. human services professionals must consider, including migration, shifting family structures, and the demand for resources and humanitarian assistance. When growth occurs primarily outside the U.S., it shapes who may seek services, the kinds of services needed, and how communities respond to diverse cultural, linguistic, and health care needs. This awareness helps practitioners anticipate changes in client populations, collaborate with international and community partners, and advocate for policies and programs that address both domestic needs and global influences on well-being. The other statements don’t fit because domestic practice is guided by U.S. law, not international laws; not all people in the U.S. are immigrants, since many are native-born or long-time residents; and U.S. policy is not dictated by the United Nations.
