- Racial disparities in arrest rates are significantly influenced by cumulative disadvantages beginning in early childhood, such as poverty and neighborhood disadvantage.
- If early-life conditions were equal across races, racial disparities in arrest rates would be nearly eliminated, highlighting the profound impact of addressing structural inequalities.
- Processes linking early-life disadvantages to arrest rates work similarly across racial groups, suggesting that systemic changes benefiting disadvantaged communities can universally reduce disparities.
Introduction
The roots of racial disparities in our criminal justice system run deeper than we ever imagined, starting long before the first encounter with the police.
This is the conclusion of a new study by Robert J. Sampson of Harvard University and Roland Neil of RAND. Published in Criminology, a top journal in the field, their study finds that the path to reducing racial disparities in arrest rates begins in childhood–and that changing the early-life conditions of Black and Hispanic children could nearly eliminate these racial disparities.
Read on to learn more about their research into racial disparities in arrest rates, and what you can do to help create a more equitable and just criminal justice system.
Background
Researchers have long sought to understand the roots of racial disparities in policing and criminal justice. Many studies, including those covered on this site, focus on identifying racial bias in police practices such as arrests, stops, searches, and the use of force:
- This body of research often tries to isolate racial bias from other factors, like differences in criminal behavior among suspects.
- These studies typically emphasize individual officer biases and the immediate context of police encounters.
- Some also consider the influence of neighborhood characteristics on enforcement.
In parallel, research on disproportionate minority contact (DMC) explores how race and legally relevant characteristics influence outcomes in the juvenile justice system:
- Studies have shown that while delinquency explains some racial differences in juvenile processing, significant disparities remain.
- For example, research using the National Youth Survey and other longitudinal studies has found that early life risk factors and neighborhood disadvantages contribute to these disparities.
Additionally, some research examines racial differences in criminal behavior over time, linking these differences to factors such as neighborhood and family contexts and even verbal ability. Studies have shown that neighborhood and family disadvantages significantly impact racial disparities in crime and arrests, with these disadvantages often beginning in childhood and continuing through adolescence.
Despite the extensive research on racial disparities in policing and criminal justice, significant gaps remain:
- Many studies focus on immediate causes and effects, overlooking the long-term historical and social processes that contribute to these disparities.
- For instance, while it’s acknowledged that historical patterns of racial inequality play a crucial role, little research has explored how these patterns accumulate and affect individuals over their lifetimes.
- This oversight is critical because the effects of racial inequality often begin long before an individual encounters the criminal justice system and can persist across generations.
“It is not that prior [studies] are wrong,” Sampson and Neil contend. “It is that by focusing on race in the moment when some deviant behavior or criminal justice decision occurs, they obscure earlier processes that produce differences in behaviors and influence exposures to official sanctioning.”
Life-Course Model of Racial Inequalities in Arrests
To address these gaps, Sampson and Neil propose a life-course model of racial inequalities in arrests. Their model, reprinted from the original article, is displayed below.
This model examines how early life social contexts contribute to racial disparities in arrests over decades and across multiple birth cohorts. Guided by Elder’s (1994) life-course principles, it focuses on structural advantages and disadvantages that originate in childhood and unfold over time. Sampson and Neil’s study attempts to link these early life conditions to arrest trajectories, emphasizing the cumulative nature of these processes.
Sampson and Neil’s approach highlights the long-term impact of structural racism and discrimination:
- Research shows that racial disparities in early life conditions, such as poverty and neighborhood disadvantage, set in motion processes that lead to cumulative advantages or disadvantages over time.
- For example, disadvantaged families often remain in high-crime neighborhoods due to a lack of resources, while those in more affluent areas enjoy protections from aggressive policing.
- These early-life conditions influence later outcomes, including employment, education, and criminal behavior.
Moreover, adverse conditions in early life can lead to lasting changes in individuals, affecting their development into adolescence and adulthood.
- For instance, exposure to lead can result in neurodevelopmental issues and increased aggression, disproportionately affecting Black children due to racial segregation.
- Similarly, subcultural adaptations like the “code of the streets,” most famously articulated by Elijah Anderson, emerge from growing up in deprived neighborhoods.
Sampson and Neil’s model suggests that if early-life conditions were equal across races, racial disparities in arrests would significantly diminish. This hypothesis underscores the importance of addressing early-life disadvantages to reduce long-term racial inequalities in criminal justice outcomes.
Sampson and Neil’s study also examines whether the impact of early-life disadvantages operates similarly across racial groups:
- Previous research indicates that structural disadvantages like neighborhood poverty and family instability affect all racial groups similarly, but are more prevalent among minorities due to historical and systemic inequalities.
- Sampson and Neil’s model extends this concept to arrest trajectories, proposing that similar disadvantages lead to comparable outcomes across racial groups, albeit at different rates due to varying exposure levels.
Finally, Sampson and Neil’s study considers how social change influences racial disparities in arrests:
- Historical and structural inequalities are persistent, of course. However, the degree of racial disparities can vary across different historical periods.
- For example, neighborhood poverty and racial segregation have durable effects across generations, influencing arrest patterns over time.
- Sampson and Neil’s hypothesis is that while the structural factors driving racial disparities remain consistent, the specific manifestations of these disparities can change with societal shifts.
Overall, Sampson and Neil’s life-course model aims to provide a comprehensive understanding of how racial inequalities in arrests develop and persist over time. By focusing on the cumulative impact of early-life disadvantages and the structural context of racial disparities, they hope to illuminate the long-term processes that contribute to these outcomes.
Methods
Sampson and Neil’s study extends the Project on Human Development in Chicago Neighborhoods (PHDCN) by examining the arrest records of participants from different racial backgrounds. The original PHDCN began in the mid-1990s and included a representative sample of children from Chicago neighborhoods, stratified by race and socioeconomic status. This design ensured a diverse range of socioeconomic exposures across racial groups.
The study initially screened over 35,000 households to identify eligible children from seven age cohorts (newborns to 18-year-olds), resulting in a sample of more than 6,200 children. Data were collected through in-home assessments, including interviews with the primary caregiver. This data collection occurred in three waves approximately 2.5 years apart, achieving a 75% participation rate in wave 1 and a 78% retention rate by wave 3.
In 2011-2013, a random sample of participants from wave 3 (aged 0, 9, 12, and 15 in the initial cohort) was re-interviewed for wave 4, achieving a 63% response rate and a sample size of 1,057 respondents.
Arrest records from 1995 to 2020 for these wave 4 participants were obtained from the Criminal History Record Information (CHRI) in Illinois, covering 25 years of data, matching names (including aliases) and birth dates with CHRI records four times between 2015 and 2021. Only participants who remained in Illinois throughout the study were included, resulting in a final analytical sample of 997 respondents, as less than 2% of the original sample moved out of state.
Sampson and Neil considered several independent variables in their study:
- Age (in years) and race (Black, Hispanic, White).
- Demographic and early-life context variables such as sex, age cohort, and immigrant generation status.
- Neighborhood conditions measured at ages 9 and 13, including poverty rate, home ownership, and educational attainment levels.
- Family structure and household context, including parental age at childbirth, marital status, household size, and length of residency.
- Socioeconomic and labor market status of parents or caregivers, such as employment status, education level, household income, and home ownership.
- Early-life neighborhood differences like crime rates, lead exposure, and collective efficacy.
- Parental criminality and family troubles, including history of arrests, incarceration, substance abuse, and exposure to violence.
These variables were correlated with arrest outcomes, specifically:
- The number of arrests between ages 10 and 40.
- Offense-specific arrests for drug offenses, violent crimes, and property crimes.
Missing data were minimal, with 62% of participants having complete data and 75% missing at most one variable. Imputation was performed using Amelia II software, and analyses were combined using Rubin’s rules.
Four main types of analyses were conducted using Poisson regression models to understand arrest patterns:
- Overall Arrest Rates: Generalized estimating equations (GEEs) were used to account for repeated measures and correlated errors. Models included covariates such as age, race, and early-life context.
- Offense-Specific Arrest Rates: Separate models were estimated for drug offenses, violent crimes, and property crimes.
- Race-Specific Models: Models were estimated separately by race to examine differences in coefficients across racial groups.
- Cohort Differences: Interaction terms between age, race, and cohort membership were used to test if racial disparities varied by cohort.
Results were presented as visualizations to aid interpretation, showing hypothetical arrest patterns for Black and Hispanic individuals if they had the same early-life conditions as White individuals. This approach provided a clearer understanding of the potential impact of early-life conditions on racial disparities in arrest patterns.
Findings
Research indicates that racial disparities in arrest rates are evident from a young age and persist throughout the life course. Analysis reveals that while the general age-crime curve is consistent across races, significant differences in the number of arrests are noticeable as early as age 10 and continue through age 40.
- White individuals experience the lowest arrest rates, peaking at an expected 0.073 arrests per person at age 20.
- In contrast, Hispanic individuals peak at 0.108 arrests at age 20
- Black individuals have the highest peak, at 0.195 arrests at age 21.
These figures highlight that Black individuals are 167% more likely to be arrested than White individuals at peak ages.
However, when adjusting for various early-life factors, the disparities in arrest rates between races begin to narrow:
- Cohort and Sex Adjustment: Adjusting for these factors minimally alters results but slightly increases the peak arrest rate for Black individuals.
- Immigrant Generation: Adjusting for immigrant background largely eliminates Black-Hispanic differences in arrests.
- Neighborhood Disadvantage: When considering neighborhood disadvantages like poverty and joblessness, the arrest rates for Black and Hispanic individuals become more similar to those of Whites.
- Family Structure and Socioeconomic Status: Adjusting for these factors further reduces the disparities, with family structure affecting Black-White differences and socioeconomic status affecting Hispanic-White differences.
- Other Early-Life Conditions: Including measures such as exposure to lead and violence does not significantly change the results, indicating these factors are captured by earlier adjustments.
Combining all adjustments nearly equalizes the arrest rates across races, reducing disparities to about 0.01 arrests per person at certain ages.
When examining specific types of arrests (violence, property, and drug offenses), the same pattern manifests. Racial disparities are evident across all types of offenses, but conditioning on early-life factors removes these disparities, except for Black arrests for violence, which remain slightly elevated but not significantly so.
Separate models for each race show that the processes linking early-life disadvantages to arrest rates work similarly across races. This supports the theory that disparities are due to differences in exposure to disadvantages rather than race-specific effects.
Comparing different cohorts shows that while absolute arrest levels have decreased for younger cohorts, racial disparities, especially between Blacks and Whites, persist. Hispanic-White disparities are not significant among younger cohorts, indicating that social changes can influence but not eliminate racial disparities.
Key findings include:
- Early-Life Contexts: If Black and Hispanic individuals faced similar early-life contexts as Whites, racial disparities in arrest counts would be minimal.
- Type of Arrests: This pattern holds for various types of offenses, rejecting the idea that specific policing practices are the sole cause of racial disparities.
- Cumulative Disadvantages: Disparities are driven by cumulative disadvantages experienced by Black and Hispanic individuals, rooted in neighborhood and family challenges.
- Consistent Processes: The processes linking early-life disadvantages to arrests work similarly across races.
- Impact of Social Change: While social change affects overall arrest rates, structural sources of racial disparities are persistent.
There are, however, several limitations to this study that the authors note:
- The study’s sample is limited to children from Chicago.
- The study does not address what White arrest patterns would look like under extreme disadvantages.
- Further research is needed on Hispanic and immigrant arrest patterns, and the detailed study of mediating mechanisms linking early-life experiences to later disparities is necessary.
- Finally, the study did not parse out differences in criminal behavior versus exposure to police, a significant area for future research.
What Can You Do?
Sampson and Neil’s study emphasizes the need for policies that address early-life inequalities to mitigate racial disparities in the criminal justice system. Racial disparities in arrest rates are deeply rooted in systemic and structural inequalities that begin early in life and persist across generations. Addressing these disparities requires both individual and collective action.
Here are some concrete steps you can take to help improve racial disparities in arrest rates and arrest rates in general:
- Educate Yourself and Others: Understanding the historical and social context of racial disparities in the criminal justice system is crucial. Read books, attend seminars, and participate in discussions about systemic racism and its impact on communities of color.
- Support and Advocate for Policy Changes: Engage in advocacy for policies that address systemic inequalities. Support legislation that promotes criminal justice reform, such as the elimination of cash bail, the reduction of mandatory minimum sentences, and the decriminalization of minor offenses.
- Promote Community Policing: Advocate for community policing strategies that build trust between law enforcement and communities. Encourage police departments to adopt practices that prioritize de-escalation and community engagement over aggressive enforcement.
- Support Organizations Working for Change: Contribute your time, skills, or financial resources to organizations dedicated to criminal justice reform and racial equality. Groups like the NAACP, ACLU, and local grassroots organizations work tirelessly to address these issues.
- Participate in Local Government: Attend town hall meetings, join local boards or commissions, and stay informed about the actions of your local government and police departments. Holding local officials accountable is key to implementing changes in policing practices.
- Encourage Education and Youth Programs: Support programs that provide educational and extracurricular opportunities for children in disadvantaged neighborhoods. Mentorship, after-school programs, and youth centers can help reduce the likelihood of involvement in the criminal justice system.
- Advocate for Economic Opportunities: Economic stability is a critical factor in reducing crime rates. Support initiatives that create job opportunities, provide vocational training, and improve access to affordable housing in marginalized communities.
- Promote Mental Health and Social Services: Advocate for increased funding for mental health and social services. Providing adequate support for mental health issues, addiction, and homelessness can reduce encounters with the criminal justice system.
- Engage in Anti-Racist Work: Commit to being actively anti-racist in your personal and professional life. Challenge racist comments, educate others about racial bias, and support diversity and inclusion initiatives in your workplace and community.
- Vote: Exercise your right to vote in local, state, and national elections. Elect officials who prioritize criminal justice reform and racial equity. Your vote can help shape policies that address systemic racism and reduce disparities in arrest rates.
By taking these actions, you can contribute to reducing racial disparities in arrest rates and promote a more equitable and just society. Every effort, no matter how small, can make a difference in addressing the systemic issues that lead to these disparities. Together, we can work towards a future where justice and equality are not just ideals, but realities for all.
