Children in immigrant families are more likely than children in native-born families to face a number of risk factors for poor developmental outcomes, including higher poverty rates, lower household incomes, and linguistic isolation, (for example, when older children and adults in a household have difficulty speaking English). Previous research suggests that food insecurity is significantly higher among children of immigrants than among children of native-born parents, even after taking into account parental work status and family income. Research also suggests that food insecurity is higher among less acculturated immigrant--those who have limited English proficiency (LEP), are noncitizens, or have more recently arrived in the United States. New analyses presented in this research brief indicate that levels of food insecurity are higher among infants and toddlers with immigrant parents than among those with native-born parents. Among these young children, food insecurity is more likely when immigrant parents are less acculturated, for instance when they are noncitizens, arrived more recently, or have limited English skills. When multiple background characteristics are considered simultaneously, parental citizenship in particular is strongly associated with food security--i.e., infants whose immigrant parents are citizens are more likely to be food secure than infants whose parents are not citizens. This research provides new insights into the prevalence and factors associated with food insecurity among households with young children of immigrants. (Contains 4 figures.) [This research brief draws on recently released data from the 9-month wave of the Early Child Longitudinal Study--Birth Cohort (ECLS-B) to present a portrait of food insecurity among young children (infants and toddlers) with foreign-born parents.]
