Unauthorized immigrants account for approximately one-fourth of all immigrants in the United States, yet they dominate public perceptions and are at the heart of a policy impasse. Caught in the middle are the children of these immigrants-youth who are coming of age and living in the shadows. An estimated 5.5 million children and adolescents are growing up with unauthorized parents and are experiencing multiple and yet unrecognized developmental consequences as a result of their family's existence in the shadow of the law. Although these youth are American in spirit and voice, they are nonetheless members of families that are "illegal" in the eyes of the law. In this article, the authors develop a conceptual framework to systematically examine the ways in which unauthorized status affects the millions of children, adolescents, and emerging adults caught in its wake. The authors elucidate the various dimensions of documentation status-going beyond the binary of the "authorized" and "unauthorized." An ecological framework brings to the foreground a variety of systemic levels shaping the daily experiences of children and youth as they move through the developmental spectrum. The article moves on to examine a host of critical developmental outcomes that have implications for child and youth well-being as well as for our nation's future.

A meta-analysis was conducted to examine gender differences in the effects of early childhood education programs on children's cognitive, academic, behavioral, and adult outcomes. Significant and roughly equal impacts for boys and girls on cognitive and achievement measures were found, although there were no significant effects for either gender on child behavior and adult outcomes such as employment and educational attainment. Boys benefited significantly more from these programs than girls on other school outcomes such as grade retention and special education classification. We also examined important indicators of program quality that could be associated with differential effects by gender.

This study uses data from a comprehensive database of U.S. early childhood education program evaluations published between 1960 and 2007 to evaluate the relationship between class size, child–teacher ratio, and program effect sizes for cognitive, achievement, and socioemotional outcomes. Both class size and child–teacher ratio showed nonlinear relationships with cognitive and achievement effect sizes. For child–teacher ratios 7.5:1 and lower, the reduction of this ratio by one child per teacher predicted an effect size of 0.22 standard deviations greater. For class sizes 15 and smaller, one child fewer predicted an effect size of 0.10 standard deviations larger. No discernible relationship was found for larger class sizes and child–teacher ratios. Results were less clear for socioemotional outcomes due to a small sample.

Little is understood about how an unconditional cash transfer might operate and affect behavior among low-income parents of infants in the United States. We investigate these questions using data from a random-assignment pilot study (N = 30) in which unconditional cash transfers were distributed monthly on debit cards to two groups of low-income parents in New York City during the first 12 months of their newborns’ lives. Mothers were randomized to receive either $100 per month or $20 per month. Mothers distinguished spending the cash transfer on essentials vs. extras, such as going out to dinner with family. The monthly cash transfer “tided them over,” even at the lower amount of $20, especially when income from other sources ran short at the end of the month. Some mothers reported saving money for unexpected expenses.

Research Findings: This study uses data from a comprehensive meta-analytic database of early childhood education (ECE) program evaluations published between 1960 and 2007 in the United States to examine the incremental effects of adding enhancement program components to ECE programs on children’s cognitive abilities, pre-academic skills, behavioral, health, and socio-emotional outcomes. Preschool enhancement programs include parenting programs, skill-based curricula, and teacher professional development programming. Our findings suggest that the addition of parent programs and skill-based curricula to ECE programs can result in improvements to a range of children’s ECE outcomes leading to better school readiness. We found no differences in the impacts of ECE programs with or without additional professional development enhancements. Practice or Policy: Designing fully-developed parent programs by explicitly targeting parents, developing academically focused and skill-based curricula, and providing additional teacher professional development enhancements to existing ECE programs can have a substantial impact on a range of children’s ECE outcomes leading to better school readiness. Further research is needed in order to determine what conditions are essential to enhancement program success as well as what conditions have negligible effects on or inhibit children’s school readiness.

Many early childhood education (ECE) programs seek to enhance parents’ capacities to support their children's development. Using a meta-analytic database of 46 studies of ECE programs that served children age three to five-years-old, we examine the benefits to children's cognitive and pre-academic skills of adding parenting education to ECE programs for children and consider the differential impacts of: 1) parenting education programs of any type; 2) parenting education programs that provided parents with modeling of or opportunities to practice stimulating behaviors and 3) parenting education programs that were delivered through intensive home visiting. The results of the study call into question some general longstanding assertions regarding the benefits of including parenting education in early childhood programs. We find no differences in program impacts between ECE programs that did and did not provide some form of parenting education. We find some suggestive evidence that among ECE programs that provided parenting education, those that provided parents with opportunities to practice parenting skills were associated with greater short-term impacts on children's pre-academic skills. Among ECE programs that provided parenting education, those that did so through one or more home visits a month yielded effect sizes for cognitive outcomes that were significantly larger than programs that provided lower dosages of home visits.

Childhood economic disadvantage is associated with lower cognitive and social-emotional skills, reduced educational attainment, and lower earnings in adulthood. Despite these robust correlations, it is unclear whether family income is the cause of differences observed between children growing up in poverty and their more fortunate peers or whether these differences are merely due to the many other aspects of family life that co-occur with poverty. Baby's First Years is the first randomized controlled trial in the United States designed to identify the causal impact of poverty reduction on children's early development. A total of 1000 low-income mothers of newborns were enrolled in the study and began receiving a monthly unconditional cash gift for the first several years of their children's lives. Mothers were randomly assigned to receive either a large monthly cash gift or a nominal monthly cash gift. All monthly gifts are administered via debit card and can be freely spent with no restrictions. Baby's First Years aims to answer whether poverty reduction in early childhood (1) improves children's developmental outcomes and promotes healthier brain functioning, and (2) improves family functioning and better enables parents to support child development. Here we present the rationale and design of the study as well as potential implications for science and policy.

Early childhood education (ECE) programs offer a promising mechanism for preventing early externalizing behavior problems and later antisocial behavior; yet, questions remain about how to best maximize ECE's potential. Using a meta-analytic database of 31 studies, we examined the overall effect of ECE on externalizing behavior problems and the differential effects of 3 levels of practice, each with increasing specificity and intensity aimed at children's social and emotional development. In short, we found that each successive level of programs did a better job than the prior level at reducing externalizing behavior problems. Level 1 programs, or those without a clear focus on social and emotional development, had no significant effects on externalizing behavior problems relative to control groups (ES=.13 SD, p<.10). On the other hand, level 2 programs, or those with a clear but broad focus on social and emotional development, were significantly associated with modest decreases in externalizing behavior problems relative to control groups (ES=-.10 SD, p<.05). Hence, level 2 programs were significantly better at reducing externalizing behavior problems than level 1 programs (ES=-.23 SD, p<.01). Level 3 programs, or those that more intensively targeted children's social and emotional development, were associated with additional significant reductions in externalizing behavior problems relative to level 2 programs (ES=-.26 SD, p<.05). The most promising effects came from level 3 child social skills training programs, which reduced externalizing behavior problems half of a standard deviation more than level 2 programs (ES=-.50 SD, p<.05).

Background

Policy debates over anti-poverty programs are often marked by pernicious stereotypes suggesting that direct cash transfers to people residing in poverty encourage health-risking behaviors such as smoking, drinking, and other substance use. Causal evidence on this issue is limited in the U.S. Given the prominent role of child allowances and other forms of cash assistance in the 2021 American Rescue Plan and proposed Build Back Better legislation, evidence on the extent to which a monthly unconditional cash gift changes substance use patterns among low-income mothers with infants warrants attention, particularly in the context of economic supports that can help improve early environments of children.

Method

We employ a multi-site, parallel-group, randomized control trial in which 1,000 low-income mothers in the U.S. with newborns were recruited from hospitals shortly after the infant's birth and randomly assigned to receive either a substantial ($333) or a nominal ($20) monthly cash gift during the early years of the infant's life. We estimate the effect of the unconditional cash transfer on self-report measures of maternal substance use (i.e., alcohol, cigarette, or opioid use) and household expenditures on alcohol and cigarettes after one year of cash gifts.

Results

The cash gift difference of $313 per month had small and statistically nonsignificant impacts on group differences in maternal reports of substance use and household expenditures on alcohol or cigarettes. Effect sizes ranged between - 0.067 standard deviations and + 0.072 standard deviations. The estimated share of the $313 group difference spent on alcohol and tobacco was less than 1%.

Conclusions

Our randomized control trial of monthly cash gifts to mothers with newborn infants finds that a cash gift difference of $313 per month did not significantly change maternal use of alcohol, cigarettes, or opioids or household expenditures on alcohol or cigarettes. Although the structure of our cash gifts differs somewhat from that of a government-provided child allowance, our null effect findings suggest that unconditional cash transfers aimed at families living in poverty are unlikely to induce large changes in substance use and expenditures by recipients.

A comprehensive evidence-based framework is needed to guide policies and programmes that enable children and adolescents to accrue the human capital required to meet the Sustainable Development Goals (SDGs). This paper proposes a comprehensive, multisectoral, multilevel life-course conceptualisation of human capital development by building on the Nurturing Care Framework (NCF), originally developed for the foundational period of growth and development through the age 3 years. Nurturing care (NC) comprises stable environments that promote children's health and nutrition, protect from threats, and provide opportunities for learning and responsive, emotionally supportive and developmentally enriching relationships. NC is fostered by families, communities, services, national policies and beyond. The principles apply across the life course, endorse equity and human rights, and promote long-term human capital. This paper presents an evidence-based argument for the extension of the NCF from preconception through adolescence (0-20 years), organised into six developmental periods: preconception/prenatal, newborn/birth, infancy/toddlerhood, preschool, middle childhood and adolescence. The proposed framework advances human capital within each developmental period by promoting resilience and adaptive developmental trajectories while mitigating negative consequences of adversities.Attaining the SDGs depends on strengthening human capital formation, extending throughout childhood and adolescence and supported by NC. Embedded in enabling laws, policies and services, the dynamic NCF components can mitigate adversities, enhance resilience and promote the well-being of marginalised groups. The life-course extension of the NCF is strategically positioned to enhance human capital, to attain the SDGs and to ensure that children or adolescents are not left behind in reaching their developmental potential.
