The Effect of the Earned Income Tax Credit on Physical and Mental health-Results from the Atlanta Paycheck Plus Experiment.

Policy Points The Paycheck Plus randomized controlled trial tested a fourfold increase in the Earned Income Tax Credit (EITC) for single adults without dependent children over 3 years in New York and Atlanta. In New York, the intervention improved economic, mental, and physical health outcomes. In Atlanta, it had no economic benefit or impact on physical health and may have worsened mental health. In Atlanta, tax filing and bonus receipt were lower than in the New York arm of the trial, which may explain the lack of economic benefits. Lower mental health scores in the treatment group were driven by disadvantaged men, and the study sample was in good mental health. CONTEXT: The Paycheck Plus experiment examined the effects of an enhanced Earned Income Tax Credit (EITC) for single adults on economic and health outcomes in Atlanta, GA and New York City (NYC). The NYC study was completed two years prior to the Atlanta study and found mental and physical benefits for the subgroups that responded best to the economic incentives provided. In this article, we present the findings from the Atlanta study, in which the uptake of the treatment (tax filings and EITC bonus) were lower and economic and health benefits were not observed. METHODS: Paycheck Plus Atlanta was an unblinded randomized controlled trial that assigned n = 3,971 participants to either the standard federal EITC (control group) or an EITC supplement of up to $2,000 (treatment group) for three tax years (2017-2019). Administrative data on employment and earnings were obtained from the Georgia Department of Labor and survey data were used to examine validated measures of health and well-being. FINDINGS: In Atlanta, the treatment group had significantly higher earnings in the first project year but did not have significantly higher cumulative earnings than the control group overall (mean difference = $1,812, 95% CI = -150, 3,774, p = 0.07). The treatment group also had significantly lower scores on two measures of mental health after the intervention was complete: the Patient Health Questionnaire 8 (mean difference = 0.19, 95% CI = 0.06, 0.32, p = 0.005) and the Kessler 6 (mean difference = 0.15, 95% CI = 0.03, 0.27, p = 0.012). Secondary analyses suggested these results were driven by disadvantaged men, but the study sample was in good mental health. CONCLUSIONS: The EITC experiment in Atlanta was not associated with gains in earnings or improvements in physical or mental health.

Advanced child tax credit payments and national child abuse hotline contacts, 2019-2022.

BACKGROUND: Children in households experiencing poverty are disproportionately exposed to maltreatment. Income support policies have been associated with reductions in child abuse and neglect. The advance child tax credit (CTC) payments may reduce child maltreatment by improving the economic security of some families. No national studies have examined the association between advance CTC payments and child abuse and neglect. This study examines the association between the advance CTC payments and child abuse and neglect-related contacts to the Childhelp National Child Abuse Hotline. METHODS: A time series study of contacts to the Childhelp National Child Abuse Hotline between January 2019 and December 2022 was used to examine the association between the payments and hotline contacts. An interrupted time series (ITS) exploiting the variation in the advance CTC payments was estimated using fixed effects. RESULTS: The CTC advance payments were associated with an immediate 13.8% (95% CI -17.5% to -10.0%) decrease in contacts to the hotline in the ITS model. Following the expiration of the advance CTC payments, there was a significant and gradual 0.1% (95% CI +0.0% to +0.2%) daily increase in contacts. Sensitivity analyses found significant reductions in contacts following each payment, however, the reductions were associated with the last three of the six total payments. CONCLUSION: These findings suggest the advance CTC payments may reduce child abuse and neglect-related hotline contacts and continue to build the evidence base for associations between income-support policies and reductions in child abuse and neglect.

The impact of stroke on employment income: A cohort study using hospital and income tax data in Ontario, Canada.

OBJECTIVE: To document the impact of stroke on employment income among people employed at the time of stroke. DESIGN: Population-based cohort study. PARTICIPANTS: People hospitalized for stroke in Ontario, Canada (2010-2014) and people without stroke matched on demographic characteristics. MAIN MEASURES: Robust Poisson regression to estimate the effects of stroke on the probability of reporting employment income on tax returns over 3 years. Quantile regression difference-in-differences to estimate the changes in annual employment income attributable to stroke. RESULTS: Stroke survivors were increasingly less likely to report any employment income poststroke, incidence rate ratios (IRR) 0.87 at 1 year (95% confidence intervals [CI]; 0.85-0.88), 0.82 at 2 years (95% CI; 0.81-0.84) and 0.81 at 3 years (95% CI; 0.79-0.82). IRR for reporting at least 50% of prestroke income levels were 0.76 at 1 year (95% CI; 0.75-0.78), 0.75 at 2 years (95% CI; 0.73-0.77) and 0.73 at 3 years (95% CI; 0.71-0.75). IRR for reporting at least 90% of prestroke income levels were 0.72 at 1 year (95% CI; 0.70-0.74), 0.66 at 2 years (95% CI; 0.64-0.68) and again 0.66 at 3 years (95% CI; 0.64-0.68). Relative changes in annual employment income attributable to stroke varied from a decrease of 13.8% (95% CI; 8.7-18.9) at the 75th income percentile to a decrease of 43.1% (95% CI; 18.7-67.6) at the 25th income percentile. CONCLUSIONS: It is important for healthcare and service providers to recognize the impact of stroke on return to prestroke levels of employment income. Low-income stroke survivors experience a more drastic loss in employment income and may need additional social support.

The Relationship Between State-Level Earned Income Tax Credits and Violent Crime.

Policies that provide economic support, such as the earned income tax credit (EITC), improve peoples' ability to meet their basic needs and reduce stress, which can reduce violence perpetration. Refundable state-level EITCs have been associated with decreases in multiple forms of violence (e.g., child abuse and neglect); however, it is unknown whether there is an association between the EITC and violent crime as captured by Uniform Crime Reports. Crime and violence remain a pressing concern for many communities across the nation. Using a longitudinal data set, we conducted fixed-effects regression models with year and state specified as fixed effects, to determine whether variations in generosity of state-level EITCs are related to the rate of violent crime. After adjusting for demographic covariates, refundable state-level EITCs remained significantly associated with reductions in criminal homicide compared to states without an EITC. As many states attempt to combat crime and prevent violence in their communities, anti-poverty measures such as the EITC provide a promising strategy for reducing the social and economic costs associated with violence.

Evidence for the Role of State-Level Economic Policy in HIV Risk Reduction: State Earned Income Tax Credit Generosity and HIV Risk Behavior Among Single Mothers.

We investigated the impact of State-level Earned Income Tax Credit (SEITC) generosity on HIV risk behavior among single mothers with low education. We merged individual-level data from the Behavioral Risk Factor Surveillance System (2002-2018) with state-level data from the University of Kentucky Center for Poverty Research and conducted a multi-state, multi-year difference-in-differences (DID) analysis. We found that a refundable SEITC ≥ 10% of the Federal Earned Income Tax Credit was associated with 21% relative risk reduction in reporting any high-risk behavior for HIV in the last year, relative to no SEITC. We also found that a 10-percentage point increase in SEITC generosity was associated with 38% relative risk reduction in reporting any high-risk HIV behavior in the last year. SEITC policy may be an important strategy to reduce the burden of HIV infections among women with low socioeconomic status, particularly single mothers.

RESUMEN: Investigamos el impacto de la generosidad del Crédito Federal Tributario por Ingreso de Trabajo a nivel estatal (SEITC) sobre el comportamiento de riesgo al VIH entre madres solteras con baja educación. Unimos los datos a nivel individual del Sistema de Vigilancia a Factores de Riesgo de Comportamiento (2002­2018) con los datos a nivel estatal del Centro de Investigación de la Pobreza de la Universidad de Kentucky, y conducimos un análisis de diferencia-en-diferencia (DID) multi-estado y multi-año. Encontramos que un reembolso SEITC ≥ 10% del Crédito Federal Tributario por Ingreso de Trabajo estaba asociado con una reducción relativa de riesgo de 21% en reportar cualquier comportamiento de riesgo alto al VIH en el último año, relativo a ningún SEITC. También encontramos que un aumento de punto porcentual de 10 en la generosidad SEITC estaba asociado con una reducción relativa de riesgo de 38% en reportar cualquier comportamiento de riesgo alto al VIH en el último año. La póliza SEITC puede ser una estrategia importante para reducir la carga de infecciones al VIH entre mujeres con bajo nivel socioeconómico, particularmente entre madres solteras.

Revisiting the effects of state earned income tax credits on infant health: a quasi-experimental study using contiguous border counties approach.

BACKGROUND: To examine the effects of refundable state earned income tax credits (EITC) on infant health. METHODS: We use the restricted-access U.S. birth certificate data with county codes from 1989 to 2018. Birth outcomes include birth weight, low birth weight, gestational weeks, preterm birth, and the fetal growth rate. The analytical sample includes single mothers with high school education or less. Two specifications of two-way fixed effects models are employed. The first specification accounts for shared time trends across all states/counties. The second specification estimates effects based on EITC changes within contiguous counties across state borders which accounts for contemporaneous events specific to each contiguous county pair. Models are estimated pooling and stratifying by parity subgroups. RESULTS: Under the first specification, refundable state EITC is associated with improved birth outcomes. Pooling all parity, a 10%-point increase in refundable EITC is associated with an 8-gram increase in birth weight (95% CI: 2.9,14.6). The effect increases by parity. In contrast, the estimates from the second model are much smaller and statistically non-significant, both pooling and stratifying by parity. CONCLUSIONS: Comparing contiguous counties across state borders, there is no evidence that refundable state EITC affects birth outcomes. However, the estimates still do not rule out moderate to large benefits for third or higher born infants.

Estimating the effect of timing of earned income tax credit refunds on perinatal outcomes: a quasi-experimental study of California births.

BACKGROUND: The largest poverty alleviation program in the US is the earned income tax credit (EITC), providing $60 billion to over 25 million families annually. While research has shown positive impacts of EITC receipt in pregnancy, there is little evidence on whether the timing of receipt may lead to differences in pregnancy outcomes. We used a quasi-experimental difference-in-differences design, taking advantage of EITC tax disbursement each spring to examine whether trimester of receipt was associated with perinatal outcomes. METHODS: We conducted a difference-in-differences analysis of California linked birth certificate and hospital discharge records. The sample was drawn from the linked CA birth certificate and discharge records from 2007-2012 (N = 2,740,707). To predict eligibility, we created a probabilistic algorithm in the Panel Study of Income Dynamics and applied it to the CA data. Primary outcome measures included preterm birth, small-for-gestational age (SGA), gestational diabetes, and gestational hypertension/preeclampsia. RESULTS: Eligibility for EITC receipt during the third trimester was associated with a lower risk of preterm birth compared with preconception. Eligibility for receipt in the preconception period resulted in improved gestational hypertension and SGA. CONCLUSION: This analysis offers a novel method to impute EITC eligibility using a probabilistic algorithm in a data set with richer sociodemographic information relative to the clinical and administrative data sets from which outcomes are drawn. These results could be used to determine the optimal intervention time point for future income supplementation policies. Future work should examine frequent income supplementation such as the minimum wage or basic income programs.

Potential mechanisms linking poverty alleviation and health: an analysis of benefit spending among recipients of the U.S. earned income tax credit.

BACKGROUND: The earned income tax credit (EITC) is the largest U.S. poverty alleviation program for low-income families, disbursed annually as a lump-sum tax refund. Despite its well-documented health impacts, the mechanisms through which the EITC affects health are not well understood. The objective of this analysis was to examine self-reported spending patterns of tax refunds among EITC recipients to clarify potential pathways through which income may affect health. METHODS: We first examined spending patterns among 2020-2021 Assessing California Communities' Experiences with Safety Net Supports (ACCESS) study participants (N = 241) and then stratified the analysis by key demographic subgroups. RESULTS: More than half of EITC recipients reported spending their tax refunds on bills and debt (52.3%), followed by 49.4% on housing, and 37.8% on vehicles. Only 3.3% reported spending on healthcare. (Note: respondents could list more than one possible spending category.) Participants ages 30 + were more likely to spend on bills and debt relative to those ages 18-29 (57.6% versus 39.4%, respectively). Other subgroup analyses did not yield significant findings. CONCLUSIONS: Our findings suggest that EITC recipients primarily use their refunds on bills and debt, as well as on household and vehicle expenses. This supports the idea of the EITC as a safety net policy which addresses key social determinants of health.

Effect of Expanding the Earned Income Tax Credit to Americans Without Dependent Children on Psychological Distress.

Antipoverty policies have the potential to improve mental health. We conducted a randomized trial (Paycheck Plus Health Study Randomized Controlled Trial, New York, New York) to investigate whether a 4-fold increase in the Earned Income Tax Credit for low-income Americans without dependent children would reduce psychological distress relative to the current federal credit. Between 2013 and 2014, a total of 5,968 participants were recruited; 2,997 were randomly assigned to the treatment group and 2,971 were assigned to the control group. Survey data were collected 32 months postrandomization (n = 4,749). Eligibility for the program increased employment by 1.9 percentage points and after-bonus earnings by 6% ($635/year), on average, over the 3 years of the study. Treatment was associated with a marginally statistically significant decline in psychological distress, as measured by the 6-item Kessler Psychological Distress Scale, relative to the control group (score change = -0.30 points, 95% confidence interval (CI): -0.63, 0.03; P = 0.072). Women in the treated group experienced a half-point reduction in psychological distress (score change = -0.55 points, 95% CI: -0.97, -0.13; P = 0.032), and noncustodial parents had a 1.36-point reduction (95% CI: -2.24, -0.49; P = 0.011). Expansion of a large antipoverty program to individuals without dependent children reduced psychological distress for women and noncustodial parents-the groups that benefitted the most in terms of increased after-bonus earnings.

The long-term effect of the Earned Income Tax Credit on women's physical and mental health.

Using a novel method, and data from the National Longitudinal Survey of Youth 1979 (NLSY79), we estimate the cumulative, long-term, causal effect of Earned Income Tax Credit (EITC) eligibility on women's physical and mental health at age 50. We find that an increase in lifetime eligible EITC benefits is associated with long-term improvements in physical health, such as reduced occurrence of activity-limiting health problems and reduced reported diagnoses of mild and severe diseases. We explore intermediate health behaviors and outcomes, and find that an increase in lifetime eligible EITC benefits increases the number of hours worked and access to employer-sponsored health insurance, and decreases body mass index in the short-term. We find no significant effects of the EITC on mental health at age 50. Finally, we find that White women benefit disproportionately from the EITC in terms of mobility-related health issues, while Black and Hispanic women benefit in terms of lung-related illnesses like asthma, as well as cancer and stroke.

Earned Income Tax Credit and Youth Violence: Findings from the Youth Risk Behavior Surveillance System.

Family- and neighborhood-level poverty are associated with youth violence. Economic policies may address this risk factor by reducing parental stress and increasing opportunities. The federal Earned Income Tax Credit (EITC) is the largest cash transfer program in the US providing support to low-income working families. Many states have additional EITCs that vary in structure and generosity. To estimate the association between state EITC and youth violence, we conducted a repeated cross-sectional analysis using the variation in state EITC generosity over time by state and self-reported data in the Youth Risk Behavior Surveillance System (YRBSS) from 2005 to 2019. We estimated the association for all youth and then stratified by sex and race and ethnicity. A 10-percentage point greater state EITC was significantly associated with 3.8% lower prevalence of physical fighting among youth, overall (PR: 0.96; 95% CI 0.94-0.99), and for male students, 149 fewer (95% CI: -243, -55) students per 10,000 experiencing physical fighting. A 10-percentage point greater state EITC was significantly associated with 118 fewer (95% CI: -184, -52) White students per 10,000 experiencing physical fighting in the past 12 months while reductions among Black students (75 fewer; 95% CI: -176, 26) and Hispanic/Latino students (14 fewer; 95% CI: -93, 65) were not statistically significant. State EITC generosity was not significantly associated with measures of violence at school. Economic policies that increase financial security and provide financial resources may reduce the burden of youth violence; further attention to their differential benefits among specific population subgroups is warranted.

Health Impact and Cost-Effectiveness of Volume, Tiered, and Absolute Sugar Content Sugar-Sweetened Beverage Tax Policies in the United States: A Microsimulation Study.

BACKGROUND: Sugar-sweetened beverage taxes are a rapidly growing policy tool and can be based on absolute volume, sugar content tiers, or absolute sugar content. Yet, their comparative health and economic impacts have not been quantified, in particular, tiered or sugar content taxes that provide industry incentives for sugar reduction. METHODS: We estimated incremental changes in diabetes mellitus and cardiovascular disease, quality-adjusted life-years, costs, and cost-effectiveness of 3 sugar-sweetened beverage tax designs in the United States, on the basis of (1) volume ($0.01/oz), (2) tiers (<5 g of added sugar/8 oz: no tax; 5-20 g/8 oz: $0.01/oz; and >20 g/8 oz: $0.02/oz), and (3) absolute sugar content ($0.01 per teaspoon added sugar), each compared with a base case of modest ongoing voluntary industry reformulation. A validated microsimulation model, CVD-PREDICT (Cardiovascular Disease Policy Model for Risk, Events, Detection, Interventions, Costs, and Trends), incorporated national demographic and dietary data from the National Health and Nutrition Examination Survey, policy effects and sugar-sweetened beverage-related diseases from meta-analyses, and industry reformulation and health-related costs from established sources. RESULTS: Over a lifetime, the volume, tiered, and absolute sugar content taxes would generate $80.4 billion, $142 billion, and $41.7 billion in tax revenue, respectively. From a healthcare perspective, the volume tax would prevent 850 000 cardiovascular disease (95% CI, 836 000-864 000) and 269 000 diabetes mellitus (265 000-274 000) cases, gain 2.44 million quality-adjusted life-years (2.40-2.48), and save $53.2 billion net costs (52.3-54.1). Health gains and savings were approximately doubled for the tiered and absolute sugar content taxes. Results were robust for societal and government perspectives, at 10 years follow-up, and with lower (50%) tax pass-through. Health gains were largest in young adults, blacks and Hispanics, and lower-income Americans. CONCLUSIONS: All sugar-sweetened beverage tax designs would generate substantial health gains and savings. Tiered and absolute sugar content taxes should be considered and evaluated for maximal potential gains.

Geographical variations of socioeconomic status and prostate cancer mortality in Taiwan.

PURPOSE: A population-wide study was conducted to determine the association between area-level socioeconomic status and prostate cancer mortality in Taiwan. METHODS: Age-period-cohort analysis was performed to adjust the time-trend variation. The area-level socioeconomic factors included proportion with a higher education, average income tax, population density, and clinical workload. RESULTS: After adjustment for time-trend variations in age, period, and cohort, prostate cancer mortality was significantly lower in the groups with the highest higher education proportion (rate ratio 0.88; 95% Confidence Intervals 0.83-0.93), average income tax (RR 0.90; 95% CIs 0.86-0.94), and population density (RR 0.88; 95% CI 0.83-0.93). When all variables were incorporated into one model, the rate ratio of prostate cancer mortality was 0.92 (95% CIs 0.88-0.97) in the region with the highest average income tax level compared with that with the lowest level, but differences in the other socioeconomic factors were not significant. CONCLUSIONS: This study revealed a significantly lower prostate cancer mortality rate in areas with a high higher education proportion, average income tax level, and population density compared with areas of low socioeconomic status in Taiwan.

State earned income tax credits and suicidal behavior: A repeated cross-sectional study.

Suicide is an increasingly common cause of death in the United States and recent increases in suicide rates disproportionately impact low income individuals. We sought to assess the impact of income support in the form of state earned income tax credit policies on suicide-related behaviors. This state-level study used repeated cross-sectional data from vital records and the National Survey of Drug Use and Health data representative at the state-level. The population included adults who either died by suicide or were selected for in-person NSDUH interviews between 2008 and 2018. Exposure was measured as the generosity of a refundable state earned income tax credit policy measured as a percentage of the federal policy. Outcomes assessed were suicidal ideation, suicidal planning, non-fatal suicide attempt, suicide deaths, and combined fatal and non-fatal suicide attempts. Analyses were performed between April and June 2020. A 10 percentage-point increase in the generosity of state earned income tax credit was associated with lower frequency of non-fatal suicide attempts (prevalence ratio [PR] = 0.96; 95% CI: 0.93-0.99), combined fatal and non-fatal suicide attempts (PR = 0.96; 95% CI: 0.93-0.99), and suicide deaths (PR = 0.99; 95% CI: 0.99-1.00). This translates to 4 fewer suicide attempts per 10,000 population each year. Generous state earned income tax credit policies are associated with reductions in the frequency of most severe suicidal behavior. Income support policies may be one way to reduce suicide attempts and death, especially among low-income adults.

The Effect of EITC Exposure in Childhood on Marriage and Early Childbearing.

Using data from the Panel Study of Income Dynamics, this study analyzes the effect of exposure to the Earned Income Tax Credit (EITC) in childhood on marriage and childbearing in early adulthood. Results suggest that EITC exposure in childhood leads women to delay marriage and first births in early adulthood (ages 16-25), but has no effect on men. A $1,000 increase in EITC exposure in childhood leads to a 2%-3% decline in a woman's likelihood of having a first birth and a comparable decline in her likelihood of marrying by her early 20s. We find similar reductions in fertility among Black and White women, though marriage declines are concentrated among White women. Results are focused on children growing up in the bottom half of the income distribution and those who spent the majority of childhood residing with a single parent-two groups that are the primary beneficiaries of the EITC. These findings have important implications for the well-being of individuals exposed to the EITC in childhood, as well as their future children.

Short-term effects of the earned income tax credit on mental health and health behaviors.

Poverty has consistently been linked to poor mental health and risky health behaviors, yet few studies evaluate the effectiveness of programs and policies to address these outcomes by targeting poverty itself. We test the hypothesis that the earned income tax credit (EITC)-the largest U.S. poverty alleviation program-improves short-term mental health and health behaviors in the months immediately after income receipt. We conducted parallel analyses in two large longitudinal national data sets: the National Health Interview Survey (NHIS, 1997-2016, N = 379,603) and the Panel Study of Income Dynamics (PSID, 1985-2015, N = 29,808). Outcomes included self-rated health, psychological distress, tobacco use, and alcohol consumption. We employed difference-in-differences analysis, a quasi-experimental technique. We exploited seasonal variation in disbursement of the EITC, which is distributed as a tax refund every spring: we compared outcomes among EITC-eligible individuals interviewed immediately after refund receipt (Feb-Apr) with those interviewed in other months more distant from refund receipt (May-Jan), "differencing out" seasonal trends among non-eligible individuals. For most outcomes, we were unable to rule out the null hypothesis that there was no short-term effect of the EITC. Findings were cross-validated in both data sets. The exception was an increase in smoking in PSID, although this finding was not robust to sensitivity analyses. While we found no short-term "check effect" of the EITC on mental health and health behaviors, others have found long-term effects on these outcomes. This may be because recipients anticipate EITC receipt and smooth their income accordingly.

Credit where it is due: Investigating pathways from earned income tax credit expansion to maternal mental health.

While earned income tax credit (EITC) expansions are typically associated with improvements in maternal mental health, little is known about the mechanisms through which the program affects this outcome. The EITC could primarily affect mental health through changes in family financial resources, changes in labor supply or changes in health insurance coverage of participants. We attempt to disentangle these mechanisms by assessing the effects of state and federal EITC expansion on mental health, employment, and health insurance by maternal marital status. We find that federal EITC expansions are associated with improved self-reported mental health for all mothers and large positive effects on employment for unmarried mothers. State EITC expansions are associated with improvements in mental health for married mothers only and have no effect on employment for married or unmarried mothers. Overall and for most subgroups of mothers, we find little association between EITC expansions and changes in health insurance coverage. These findings suggest that while EITC expansions improved mental health for unmarried mothers through a combination of the credit and employment effects, for married mothers, improved mental health is driven through the direct credit alone.

The earned income tax credit and infant health revisited.

Hoynes, Miller, and Simon (2015), henceforth HMS, report that the national expansion of the Earned Income Tax Credit (EITC) is associated with decreases in low birth weight. We question their findings. HMS's difference-in-differences estimates are unidentified in some comparisons, while failed placebo tests undermine others. Their effects lack a plausible mechanism as the association between the EITC and prenatal smoking also fails placebo tests. We contend that the waning of the crack epidemic is a possible confound, but we show that any number of policies directed at poor women also eliminate the effect of the EITC when aggregated to the national level. Identifying small, causal effects of a national policy at a single point in time is exceedingly challenging.

State Earned Income Tax Credit policies and intimate partner homicide in the USA, 1990-2016.

Economic insecurity is a risk factor for intimate partner homicide (IPH). The Earned Income Tax Credit (EITC) is the largest cash transfer programme to low-income working families in the USA. We hypothesised that EITCs could provide financial means for potential IPH victims to exit abusive relationships and establish self-sufficiency. We conducted a national, quasiexperimental study of state EITCs and IPH rates in 1990-2016 using a difference-in-differences approach. The national rate of IPH decreased from 1.9 per 100 000 adult women in 1990 to 1.3 per 100 000 in 2016. We found no statistically significant association between state EITC generosity and IPH rates (coefficient indicating change in IPH rates per 100 000 adult female years for additional 10% in amount of state EITC, measured as the percentage of federal EITC: 0.02, 95% CI -0.03 to 0.08). Financial control associated with abuse and current EITC eligibility rules may prevent potential IPH victims from accessing the EITC.
