To derive new insights into the growing number of multiethnic, immigrant, transnational families in the United States and abroad, we need to incorporate the concept of globalization into our analysis. As the world becomes increasingly interconnected, an ever-growing number of heterogeneous individuals are associating with each other and being exposed to new lifestyles, behaviors, and cultural values. This exposure is leading to increased heterogamous relationships and families. The fluidity, flow, and dynamism that characterizes contemporary social life is a critical aspect of understanding multiethnic, immigrant, transnational families. To conduct research and design policies that encourage the well-being of families, we need to integrate into family scholarship a focus on economics, migration, and varied beliefs and values.
