Using nationally representative survey data, this research note examines the association between immigrant legal status and poverty in the United States. Our objective is to test whether estimates of this association vary depending on the method used to infer legal status in survey data, focusing on two approaches in particular: (1) inferring legal status using a logical imputation method that ignores the existence of legal-status survey questions (logical approach); and (2) defining legal status based on survey questions about legal status (survey approach). We show that the two methods yield contrasting conclusions. In models using the logical approach, among noncitizens, being a legal permanent resident (LPR) is counterintuitively associated with a significantly greater net probability of being below the poverty line compared with their noncitizen peers without LPR status. Conversely, using the survey approach to measure legal status, LPR status is associated with a lower net probability of living in poverty, which is in line with a growing body of qualitative and small-sample evidence. Consistent with simulation experiments carried out by Van Hook et al. (2015), the findings call for a more cautious approach to interpreting research results based on legal status imputations and for greater attention to potential biases introduced by various methodological approaches to inferring individuals’ legal status in survey data. Consequently, the approach used for measuring legal status has important implications for future research on immigration and legal status.

Objective. We describe our Fall 2020 study of college students' COVID-19 related behaviors, attitudes, and antibody test results. Participants. The study included 1,446 randomly selected and self-enrolled undergraduate and graduate students from a midwestern university. Methods. An online survey was distributed to a sample of students, between September and December 2020. A sub-group also participated in a SARS-CoV-2 antibody blood draw. Results. Nearly half of students reported a prior COVID-19 test with 22% indicating a positive test, which represents an 11% positivity rate across all student participants. Of those who participated in antibody testing, 15.1% tested positive for SARS-CoV-2 antibodies. Seventy-seven percent of participants said they would get vaccinated. One-third of students reported moderate to severe generalized anxiety disorder and 13% reported moderate to severe depression. Conclusions. This study informed campus decisions in Fall 2020. The importance of effective public health messaging on campus should continue in the future. Keywords: behavior; COVID-19; immunology; students; transdisciplinary research
