Final answer:
Marriages that cross racial and ethnic lines have become more common in the US. Factors that might encourage exogamy include the removal of miscegenation laws, equal rights, legal protection against racism, and the reduction of social stigma attached to racial exogamy. Acculturation, assimilation, and cultural values such as love and compatibility can also influence intermarriage.
Step-by-step explanation:
Marriages that cross racial and ethnic lines have become more common in the US, although most US marriages are still racially and ethnically endogamous. Factors that might encourage exogamy include the removal of miscegenation laws, equal rights, legal protection against racism, and the reduction of social stigma attached to racial exogamy. Acculturation and assimilation can also influence intermarriage, as ethnic minorities living among a larger population tend to adapt to the beliefs and practices of the larger group. Additionally, cultural values such as love and compatibility can play a role in exogamous marriages.
