ࡗ Families in Poverty in the 1990s: Trends, Causes, Consequences, and Lessons Learned During the 1990s, poverty rates in the United States remained relatively stable despite a robust economy in which unemployment and inflation were at their lowest points in many years. Approximately 13% of individuals, 11% of families, and 19% of children lived below the poverty line in 1998, a decline of only 1% or less for each of these categories since 1990. These high rates of poverty result in many severe consequences. This essay reviews the research and theoretical and conceptual developments during the past decade, including: (a) a background on how the poverty line was developed; (b) general research themes in the 1990s; (c) the causes of the virtually unchanged poverty rate; (d) the consequences of poverty, particularly for children; and (e) the lessons we have learned from research over the past decade, with some directions for the future.
