The UC Davis Center for Poverty & Inequality Research
mission is to facilitate non-partisan academic research on
poverty in the U.S., disseminate this research, and train
the next generation of poverty scholars. Our research agenda
includes four themed areas of focus: labor markets and poverty,
children and intergenerational transmission of poverty, the
non-traditional safety net, and immigration.
In recent years, cash-assistance programs have been piloted across the United States, typically as Guaranteed Income (GI). In a recent study, we explored how these programs are being designed and evaluated. Reviewing 105 programs covering over 40,000 beneficiaries, we compared eligibility criteria, funding sources, distribution amounts, program administration, pilot duration, and evaluation measures.
In a recent study, we investigated pediatric-onset conditions in the US, seeking to identify recent trends as well as opportunities for prevention and intervention. Specifically, we analyzed chronic conditions (CC) and functional limitations (FLs) in more than 236,000 children (5-17 years) and young adults (18-25 years) between 1999 and 2018.
Though racial disparities in infant health conditions have persisted for decades, evidence regarding their long-term consequences has been limited. In a recent study, I used administrative data from Texas and the shift to Medicaid Managed Care (MMC) to examine the later effects of prenatal MMC on key schooling outcomes.

Rocío’s story of moving back and forth between the U.S. and
Mexico isn’t like any you’ve heard before. It began when her
daughter, 15 at the time, ran away with a man who took her from
Mexico City to the U.S.
UC Davis is a powerhouse for breakthroughs and impact. Our
interdisciplinary research plays a vital role in building the
region’s economy. Our research contributes to our nation’s global
leadership in technology and innovation. Through collaboration
between our top-ranked hospital and veterinary school, as well as
our science and engineering discoveries, our research directly
improves American lives.
In 2022, Yolo County Health and Human Services Agency(HHSA)
launched the Yolo County Basic Income (YOBI)project and engaged
the UC Davis Center for Regional Change to evaluate the project
via the collection of survey data from YOBI participants. The
YOBI project was designed to address the county’s poverty, which
is ~25%higher than the California rate reported in the 2021
Census.
COVID-19 May Have Been Job Related for One Fourth of
Diagnosed Adults
We catch COVID-19 from each other. The fewer people we
encounter,
the safer we will be. Our desire for fewer encounters was
especially apparent in employment arrangements during the first
two and a half years
of the pandemic. Most workers whom employers allowed to work from
home did so; most whose employers did not allow this reported to
their workplaces.
Objectives: To test for the effects of wages on smoking using
labor unions as instrumental variables. Methods: We analyzed four
waves of the Panel Study of Income Dynamics (2013 to 2019
alternate years). The overall sample included workers aged 18 to
70 years in 2013 and subsamples within blue clerical/white-collar
and private/public sector jobs (N = 37,117 to 8446 person years).
We used two instrumental variables: worker’s union membership and
states’ right-to-work laws.

Lenna Ontai is a Professor of Cooperative Extension whose work
focuses on the development of children’s health-related behaviors
in the family context. Her current work is focused on
understanding how families navigate barriers to facilitating
children’s adoption of healthy lifestyle behaviors in early
development. She actively translates and disseminates research in
this area to inform UC Cooperative Extension programs that serve
families living with limited incomes.
Trained in environmental health and epidemiology, Dr. James has
focused his research on estimating the influence of spatial
factors, including exposure to nature, the built environment, the
food environment, air pollution, light pollution, noise, and
socioeconomic factors, on health behaviors, mental health, aging,
and chronic disease within large prospective cohort studies. He
has developed methodologies link smartphone-based global
positioning systems (GPS) and wearable device accelerometry data
to understand how spatial factors influence health behaviors.

California, Davis. She is a scholar of migration, race and
ethnicity, and political sociology focusing on the experiences of
Latina/os in the United States.
Dr. Dulce Westberg is an Assistant Professor of Psychology
at the University of California, Davis. Her research examines how
individuals from racially and ethnically minoritized groups
navigate social structures, and how these structures shape
personality and identity development. Drawing on both qualitative
and quantitative methods, she explores life narratives related to
race, ethnicity, gender, and social class to understand their
links to psychosocial adjustment.
I study neighborhood inequality in US cities. Why are some
neighborhoods more disadvantaged than others? What are the
consequences of neighborhood disadvantage for health and
well-being? What are the causes and consequences of moving to a
more-advantaged neighborhood?
I have a specific interest in understanding these issues as they
relate to adolescents and young adults, with a particular focus
on the ways in which schools and neighborhoods interact to impact
poverty and inequality.

I’m interested in understanding how structural adversities impact
the educational achievement and wellbeing of marginalized
children. I also focus on how school policies, practices, and
programs can support the wellbeing of vulnerable youth
populations, including children in the foster care system and
those facing schooling-related challenges like chronic
absenteeism and bullying.
I am primarily interested in the connections between
schooling and social inequality. In addition to the
Department of Sociology, I am also on the faculty of the Graduate
Group in Education.
A major question that motivates Erin’s research is how inequality
is generated and/or changed through migration and the policies
that regulate migration. Erin has studied:
Children’s development of self-regulation and behavior problems,
how they relate to parents’ mental health and parenting, and
their contributions to mental illness in childhood and
adolescence.

Her research interests are in labor economics. Much of her work
focuses on studying the determinants of inequality in education.
Through her work, she seeks to better understand how individuals’
educational investment decisions are shaped by their environments
and backgrounds, and, in particular how policies or programs that
impact vulnerable youth can sere to reduce (or exacerbate)
pre-existing gaps in later life.

Robert Faris uses social network analysis to investigate how
health risk behaviors, including bullying, dating violence,
substance use, and delinquency, spread through social ties and
are structured in the social hierarchies of schools.
His recent work shows that adolescents bully their own friends,
as well as schoolmates with whom they share friends, to achieve
higher social status, and examines the moderating role of network
stability in this dynamic.
