Fifty years ago, President Lyndon B. Johnson declared a War on Poverty, and introduced legislation aiming to reduce the national poverty rate. As shown in this chart, in 1964, 23 percent of U.S. children lived in poverty. Since then, the rate has fluctuated quite a bit, but the latest child poverty rate (22 percent, for 2012) is barely lower than it was when the War began. Poverty rates for black and Hispanic children (at 39 and 34 percent, respectively) are even higher. Below, we highlight five ways poverty is harmful to children, and why it’s imperative to continue this fight.
How developmental science understands child poverty has changed a great deal in recent years. Poverty, for children, is not simply a matter of getting by with less of the essentials of life. Particularly at its extremes, poverty can negatively affect how the body and mind develop, and can actually alter the fundamental architecture of the brain. Children who experience poverty have an increased likelihood, extending into adulthood, for numerous chronic illnesses, and for a shortened life expectancy.
Children growing up in poverty, when compared with their economically more secure peers, fall behind early. Starting in infancy, gaps are evident in key aspects of learning, knowledge, and social-emotional development. When left unaddressed, these early gaps become progressively wider. Early optimal development tends to open doors to further optimal development, while impoverished development tends to close those doors. So, poor children lag behind their peers at entry to kindergarten, in reading ability at the end of third grade, in the important self-monitoring skills often called “executive functioning,” and in school attendance in eighth grade. Poor children are more likely to drop out of school, or fail to obtain post- secondary education.
Even when poverty doesn’t directly alter human biological systems, we know that growing up poor increases the likelihood that children will have poor health, including poor emotional and behavioral health. Poverty works in multiple ways to constrict children’s opportunities and expose them to threats to well-being. Poor children are more likely to lack “food security,” as well as have diets that are deficient in important nutrients. Rates of several chronic health conditions, such as asthma, are higher among poor children. They areless likely to receive preventive medical and dental care.
While direct causal links between neighborhood poverty and children’s outcomes are challenging to identify in research, scholars have found that growing up in neighborhoods with concentrated poverty is associated with negative academic outcomes, more social and behavioral problems, and poorer health and physical fitness outcomes. Poor children are more likely to live in neighborhoods where they are exposed to environmental toxins and other physical hazards, including crime and violence. In the case of violence, evenindirect exposure — witnessing, or simply hearing of its occurrence — has been linked with adverse developmental outcomes. Poor children are also disproportionately likely to attend schools in districts with fewer resources, with facilities that are grossly inadequate, and with school leadership that is more transient.
While the strengths of poor families are often overlooked, parents experience numerous challenges that can affect their own emotional well-being, as well as their children’s. Poor parents report higher stress, aggravation, and depressive symptoms than do higher-income parents. Parents with scarce economic resources face difficulty planning, preparing, and providing for their families’ material needs. Children in poor families have fewer books and other educational resources at home, and they are less likely to experience family outings, activities, and programs that can enrich learning opportunities. Their families are more likely to experience housing instability. Direct evidence that additional income can improve children’s lives comes from several experimental evaluations: programs that increased family income showed improvements in children’s social and academic outcomes.
