Spurred in part by the rapid growth of the Hispanic population, considerable progress has been made over the past several decades in documenting the family behavior of Hispanics. Scholars increasingly recognize the importance of disaggregating the Hispanic population by national origin and generation, but the literature remains inconsistent in this regard. With an emphasis on demographic indicators of family behavior, this review summarizes trends in marriage, fertility, and family/household structure among the major Hispanic subgroups and identifies key issues in the literature that attempts to explain existing patterns. The role of generation is systematically addressed, as are the shortcomings of the standard practice of using cross-sectional data on generation to draw inferences about assimilation. We conclude that new research designs are needed to address the complexities of the migration process and their links to family patterns. In addition, future research should push toward greater integration of cultural and structural perspectives on how Hispanic families are shaped.
