During the past decade, scholars continued to focus on how larger economic trends impacted families across the income spectrum. From income and wealth inequality to economic insecurity, the gaps between the haves and the have nots remained, and some widened during this period. The authors' comprehensive review found the following three major takeaways: first, the biggest economic divides run through families with children; second, low‐income families face concentrated disadvantage marked by insecurity and precarity; and third, inequality and insecurity shaped the “dynamism” of family life, including how families respond culturally and emotionally to economic changes, and how these responses unfold over time. They examine active areas of research, including parenting trends and the transition to adulthood. They also document a new scholarly emphasis on uncertainty and instability along with the forces that exacerbate or mitigate them, such as job quality, economic volatility, wealth, and incarceration. Research during the past decade focused on the experience and consequences of dynamism, reflecting not only the reality that families evolve but also that they face continual change in their economic, social, and political contexts. The authors highlight research investigating how families “do dynamism,” work that looks over time or offers in‐depth examinations of how families adapt to and cope with dynamism every day. This research reveals that inequality and insecurity are not only matters of levels and gaps but also ongoing matters of meaning‐making, identity, and feeling. The authors conclude by highlighting some strengths and weaknesses of these research streams and pointing out new avenues for future scholarship.
