Abstract

Introduction

This study estimated the per-victim U.S. lifetime cost of rape.

Methods

Data from previous studies was combined with current administrative data and 2011 U.S. National Intimate Partner and Sexual Violence Survey data in a mathematical model. Rape was defined as any lifetime completed or attempted forced penetration or alcohol- or drug-facilitated penetration, measured among adults not currently institutionalized. Costs included attributable impaired health, lost productivity, and criminal justice costs from the societal perspective. Average age at first rape was assumed to be 18 years. Future costs were discounted by 3%. The main outcome measures were the average per-victim (female and male) and total population discounted lifetime cost of rape. Secondary outcome measures were marginal outcome probabilities among victims (e.g., suicide attempt) and perpetrators (e.g., incarceration) and associated costs. Analysis was conducted in 2016.

Results

The estimated lifetime cost of rape was $122,461 per victim, or a population economic burden of nearly $3.1 trillion (2014 U.S. dollars) over victims’ lifetimes, based on data indicating >25 million U.S. adults have been raped. This estimate included $1.2 trillion (39% of total) in medical costs; $1.6 trillion (52%) in lost work productivity among victims and perpetrators; $234 billion (8%) in criminal justice activities; and $36 billion (1%) in other costs, including victim property loss or damage. Government sources pay an estimated $1 trillion (32%) of the lifetime economic burden.

Conclusions

Preventing sexual violence could avoid substantial costs for victims, perpetrators, healthcare payers, employers, and government payers. These findings can inform evaluations of interventions to reduce sexual violence.

INTRODUCTION

An estimated 19.3% of U.S. women and 1.7% of men have been raped during their lifetime.1 Sexual violence victimization is associated with poor short- and long-term physical and mental health outcomes.2,3

Few studies have quantified the per-victim lifetime economic cost of sexual violence, which at a minimum includes victims’ impaired health, as well as lost productivity and criminal justice activities. A per-victim cost here refers to the value of a person entirely avoiding a particular exposure. Previous studies have estimated related cost dimensions—such as cost per sexual assault incident4–8—but largely have not accounted for victims’ long-term health. The aim of this study was to use data from previous studies with current administrative and sexual violence surveillance data to estimate the per-victim U.S. lifetime cost and total population economic burden of rape among adults not currently institutionalized.

METHODS

Study information reported according to Consolidated Health Economic Evaluation Reporting Standards.9 Model inputs included the number of U.S. adult (aged ≥18 years) women and men with any lifetime (including childhood) and past 12–month incidence of rape; selected attributable—or marginal—health and other outcomes associated with rape from administrative data and previous studies (hereafter, reference studies); and the marginal cost of those outcomes. Marginal outcome refers to the proportion of victims with an outcome beyond the proportion among non-victims, and is used to calculate the attributable cost of rape. Medical, lost work productivity, and criminal justice costs were included. The main outcome measures were:

  1. lifetime cost of rape per victim; and

  2. lifetime cost of rape in the U.S. population (or economic burden) of currently non-institutionalized adults (hereafter, U.S. population), calculated as the lifetime cost per victim multiplied by the population number of victims.

This analysis used a lifetime time horizon from the societal perspective. Previous studies of lifetime per-person health costs have identified a meaningful age of inception—for example, age 6 years for nonfatal child maltreatment10 (estimated cost: $210,012 as 2010 U.S. dollars [USD], or $225,408 as 2014 USD11) and age 24 years for smoking12 (estimated cost: $220,000 for men and $106,000 for women as 2000 USD, or $292,010 and $139,119 as 2014 USD11). The authors did not find a robust estimated average age of first rape among victims, although it is known that the age of first completed rape was <18 years for 42% of female victims (and <25 years for 80% of female victims) and <10 years for 25% of male victims.13 The present model assessed lifetime unit costs assuming an average age of first rape victimization of 18 years. Costs incurred after the first year were discounted by 3%14 and presented as 2014 USD, inflated using selected indices.11,15 The analysis was conducted in 2016 and used publicly available data.

Definition and Prevalence of Rape

The economic burden estimate is based on the estimated number of currently non-institutionalized men and women who reported having been raped at some point during their lives in the 2011 U.S. National Intimate Partner and Sexual Violence Survey (NISVS)1 (data collection, January–December 2011) where rape was defined as completed or attempted penetration of the victim through the use or threats of physical force or when the victim was drunk, high, drugged, or passed out and unable to consent (Table 1).

Outcomes and Unit Costs

Rape outcomes, identified through a targeted literature search, were included based on reference studies’ representativeness (Appendix Table 1, available online). National studies and meta-analyses addressing both male and female victims were prioritized. Outcomes had to be reported in a way that facilitated calculation of victims’ marginal probability of the outcome; for example, the outcome prevalence among non-victims and an AOR of the relationship between the outcome and respondents’ experience of rape.44 Studies that assessed outcomes among adult (i.e., aged ≥18 years) respondents and aligned with the NISVS rape definition were prioritized. Unit costs represented the attributable cost of analyzed outcomes, based on direct comparison of affected and unaffected individuals (Appendix Table 2, available online). Comprehensive lifetime unit costs that included both medical care and lost work productivity were prioritized. Where only annual unit costs were available, lifetime costs were estimated by multiplying the annual cost over the age range of respondents in the cost reference study (Appendix Table 3, available online), bounded by the average assumed age at first rape victimization (i.e., 18 years) and current life expectancy (i.e., 79 years).45 The cost of prevention efforts was excluded.

Average annual data from the 2010–2014 U.S. National Crime Victimization Survey indicated 10.9% (n = 18,012/165,034 survey weighted) of attempted or completed rape victimizations (including male and female victims) involved victim property loss or damage, valued at an average $219 per affected victim (Table 1) (U.S. Department of Justice, Bureau of Justice Statistics, personal communication, 2015).

Among attempted or completed rape victimizations (N=216,570 surveyed weighted) from annual average 1995–2014 National Crime Victimization Survey data, 5.3% of victims were treated for nonfatal injuries in a doctor’s office, 12.1% in an emergency department, and 1.0% as inpatients (Table 1) (U.S. Department of Justice, Bureau of Justice Statistics, personal communication, 2015). Unit costs were estimated payment for a doctor’s visit16 and the discounted lifetime medical cost associated with an emergency department visit or hospital admission for sexual assault (Pacific Institute for Research and Evaluation, personal communication, 2016) (Table 1). In 2011, there were an estimated 18 murders associated with rape crimes (Appendix Table 1, available online).17 Unit costs were based on an estimated lifetime cost of medical care and lost productivity due to homicide.18

Data from a national sample of women (N=3,031 respondents) indicated that 4.8% of completed penetration rape victims experienced rape-related pregnancy (Table 1).19 Among a small sample of rape-related pregnancies (N=34), 11.3% resulted in spontaneous abortion, 50.0% in medically assisted abortion, 32.3% of women kept the baby, and 5.9% of women gave the baby up for adoption.19 Unit costs were estimated payments for medical treatment for spontaneous abortion,23 medically assisted abortion,22 pregnancy and delivery,20 and the public payer cost of adoption from age 0 to 18 years (i.e., social services)21 applied to the estimated proportion of women with rape-related pregnancy by outcome among those with lifetime experience of completed penetration rape among all women victims of attempted and completed rape in 2011 NISVS (n=13,826,000/23,305,000, or 59%) (Table 1).1

Female victims of intimate partner rape aged ≥18 years (N=322,230 victimizations, survey weighted) documented in the National Violence Against Women Survey was calculated as an average 3.6 productive days missed per victim (Appendix Table 2 [available online] provides calculations).46 This number of days was multiplied by an estimated U.S. population (aged ≥15 years) daily production value24 to estimate the value of short-term lost productivity due to rape ($516 in 2014 USD) (Table 1).

Funding for victims’ services through the criminal justice system at the federal, state, and local levels—including U.S. Department of Justice grants and Violence Against Women Act (Title IV, P.L. 103-322)47 funding—are comprehensively included in the criminal justice estimates through a top-down accounting approach (Appendix reports calculation details, available online). This approach was deemed the best use of available data, but means the authors could not identify the cost of individual victim services (e.g., rape kit processing). Although previous studies have estimated the cost of annual victim services for two state governments,5,8 it was determined infeasible to comprehensively and accurately assess the proportion of victims accessing services and the cost of response (as opposed to prevention) services per victim using a bottom-up accounting approach.

A meta-analysis of studies published in 1980–2008 indicated significantly higher observed prevalence of mental health outcomes—anxiety, depression, eating disorder, post-traumatic stress disorder, and suicide attempt—among adolescent and adult respondents with lifetime (primarily childhood) experience of sexual abuse (Table 1).2 The proportion of nonfatal suicide attempts requiring medical care was estimated using data for men (59.0% of attempts) and women (31.1% of attempts) in a separate national sample study of adolescent rape victims.29 Unit costs were estimated lost work productivity and medical costs for anxiety disorder,25 major depressive disorder,26 eating disorders,27 post-traumatic stress disorder,25,28 and medically serious nonfatal suicide attempts18,30 (Table 1).

The 2005 Behavioral Risk Factor Surveillance System survey indicated significantly higher observed prevalence of excess alcohol and tobacco use among adults (aged ≥18 years, N=115,030 respondents) with lifetime experience of unwanted attempted or completed sex (Table 1).3 Unit costs were attributable estimated lost work productivity and medical costs for excess alcohol use31,32 and smoking12 (Table 1). The 1990–1992 National Comorbidity Survey documented significantly higher prevalence of drug problems among adults (aged ≥15 years, N=5,877 respondents) who were raped or molested during childhood or adolescence (Table 1),33 supporting other research among a national sample of women.48,49 Unit costs were estimated lost productivity and medical costs34,35 (Table 1).

The 2005 Behavioral Risk Factor Surveillance System data indicated significantly higher observed prevalence of asthma and joint conditions among sexual violence victims (Table 1).3 Unit costs were estimated lost work productivity and medical payments for asthma36 and joint pain39 (Table 1). Kentucky Women’s Health Registry data indicated significantly higher observed prevalence of cervical cancer among women (aged ≥15 years, N=4,732 respondents) with lifetime forced sexual experiences (Table 1).37 Unit costs were estimated medical payments38 and lost productivity38 attributable to cancer, assigned among the estimated number of women with lifetime completed penetration rape in 2011 U.S. NISVS (n=13,826,000) (Table 1). A U.S. health plan study indicated a higher observed prevalence of sexually transmitted infections among adults (aged ≥19 years, N=9,323 respondents) who experienced attempted or completed rape during childhood or adolescence (age ≤ 18 years)40 (Table 1). Unit cost were estimated medical costs41,42 and lost work productivity43 (Table 1).

An attribution method was used to estimate the per-victim discounted lifetime average criminal justice cost associated with sexual violence among total annual U.S. government criminal justice spending (Table 2 and Appendix [available online]).50 Lost productivity due to incarceration is the annual production value of the U.S. non-institutional population multiplied by the average estimated number of years sexual violence perpetrators are incarcerated (Tables 1 and ​and2,2, Appendix [available online]).

Analysis

The marginal probability of selected outcomes was multiplied by associated unit costs to estimate the per-person lifetime cost of rape, separately for men and women. The sex-specific, per-person estimated cost of rape was multiplied by the estimated number of men and women with lifetime experience of rape to estimate the total U.S. lifetime burden of rape. Government costs were assessed as the sum of criminal justice and adoption costs, plus the estimated government share of all medical spending (i.e., 59.8%).63

RESULTS

The present-value, per-victim estimated lifetime cost of rape was $122,461, or $3.1 trillion for all victims, based given new information about victim outcomes or unit on 23 million U.S. women and 2 million men with costs. Barring substantial changes to the per-victim cost lifetime experience of rape (Table 1).

DISCUSSION

The per-victim lifetime cost of rape ($122,461) can be interpreted as the cost averted for each potential victim who avoids rape. The per-victim estimate could change given new information about victim outcomes or unit costs. Barring substantial changes to the per-victim cost estimate, the lifetime economic burden of rape estimate ($3.1 trillion) will remain relatively stable; this estimate reflects the per-victim cost multiplied by the number of U.S. adults with lifetime experience of rape, and such a large population experiences modest incremental demographic changes. The estimated number of victims with rape experience in the past 12 months had a minor impact on the economic burden through the criminal justice and fatalities estimates. The economic burden represents costs over victims’ lifetimes. Though the authors do not know what proportion of victims in the previous 12 months (an estimated 1,929,000 women1 and 219,000 men [unpublished data]) were first-time victimizations, applying this study’s per-victim cost estimate to that annual number of victims yields an approximate annual economic burden of $263 billion.

The per-victim estimate is the minimal identifiable cost of rape. This study did not include non-monetary elements, sometimes presented as intangible costs—a monetized version of victims’ pain and suffering.4,8 Previous studies have estimated the per-offense cost of rape and sexual assault to be $87,000 (1993 USD) to $240,776 (2008 USD) (or approximately $130,775 to $263,772 as 2014 USD11), of which 80% to 95% were intangible costs.4–6,8 Recognizing victims’ pain and suffering is unquestionably important, but must be weighed against the conceptual and computational challenges of monetizing pain and suffering.64 Costs to victims’ and perpetrators’ friends and families, and costs of other forms of sexual violence (e.g., being made to penetrate or sexual coercion) were not included. NISVS estimates do not include the currently institutionalized population, though would capture experiences among the previously institutionalized. Health outcomes that could be linked to specific attributable costs were included, though activity limitations, gastrointestinal symptoms, high cholesterol, HIV risk factors, non-specific pain, overweight, and urinary problems have higher prevalence among sexual violence victims.3,65,66 Many lost productivity unit estimates included only employed respondents, and valued respondents’ productivity using the human capital approach (i.e., lost wages). This approach, though commonly used, undervalues lost productivity overall and undervalues female losses, in particular, because women are often paid less than men. Many lost productivity estimates did not include mortality. Long-term lost productivity among rape victims not diagnosed with any of the analyzed outcomes was not included.

Discounting assumed victims’ age at first rape was 18 years, which underestimates/overestimates costs among victims with first rape at age <18 years/> 18 years. If one instead applies the average age of rape victimizations among adolescents and adults—27 years67—the estimated cost per victim decreases modestly to $119,277, with a population economic burden still exceeding $3 trillion. Too few reference study estimates included measures of dispersion for a meaningful probabilistic sensitivity analysis (Appendix Tables 1 and 2, available online). Based on available data, the authors have not included the medical cost of follow-up visits for sexually transmitted infection testing that takes place after an initial medical visit for rape treatment. Identifiable double counting of costs includes the following: HIV costs appear in both sexually transmitted infection and illicit drug use unit costs, and some costs for anxiety and drug and alcohol dependence are included in the depression unit cost (Appendix Tables 1 and 2, available online). Substance use constitutes approximately a quarter of the per-victim cost; crime costs are a major component of contributing unit costs for substance abuse, and a small portion (<1%) of those unit costs included research and prevention activities related to alcohol and drugs.12,31,32,34,35 Some reference studies focused on outcomes exclusively among adults who experienced childhood rape (Appendix Table 1, available online). The cost of some lifetime experiences was inferred from available annual cost data (Appendix Table 3, available online), which implicitly assumes an accurate distribution of patients at all stages of a particular outcome (i.e., acute, recurring, remission) in reference studies’ annual estimates.

Limitations

This study is notably limited by inexact timelines related to rape occurrence during victims’ lifetimes, number of rape incidents per victim, number of victims per perpetrator, onset of attributable health outcomes, and treatment of those outcomes. This study’s estimates are per victim, rather than per victimization, which certainly underestimates consequences among some victims and the acute costs associated with victimization.68 Another major limitation is that this study assumed that rape is the cause of victims’ higher observed prevalence of health-related conditions, although the status of these conditions as risk factors for, correlates with, or outcomes of sexual violence is complex.69 Future analysis of longitudinal data identifying sexual violence and health outcomes might address these issues, along with issues related to timing of rape exposure and the effects of multiple victimizations.

CONCLUSIONS

Despite limitations, this study’s economic burden estimate included more comprehensive information on victims’ lifetime mental and physical health than previous estimates. This study incorporated new national surveillance data from NISVS indicating rape affects many times more individuals than other sources have suggested previously. These findings can inform evaluations of interventions to prevent sexual violence, identifying cost-effective approaches to eliminate rape and its substantial impact on public health.
