Walk Free

Walk Free is an international organization headquartered in , , dedicated to eradicating modern through rigorous research, policy advocacy, and partnerships with governments, businesses, and groups.
Established in 2011 by Grace Forrest, who serves as its Founding Director after witnessing child exploitation during her time at a rescue home in , the organization was co-founded by Australian mining billionaire and operates as an initiative of the Minderoo Foundation, his family's philanthropic entity funded primarily by proceeds from Fortescue Metals Group.
Walk Free's flagship contribution is the (GSI), a data-driven report series launched in 2013 that estimates modern prevalence across over 160 countries using household surveys, NGO reports, and survivor testimonies; the 2023 edition, drawing on 2021 data, calculated 49.6 million people living in modern globally—an increase of 10 million from 2016 estimates—predominantly in forms such as forced labor and , with highest concentrations in nations like , , and .
The GSI has influenced international policy, including collaborations with the , by highlighting vulnerabilities in supply chains and conflict zones, yet it has faced substantive methodological critiques from experts for relying on inconsistent data inputs, expansive definitions that bundle disparate exploitations under "modern ," and potential overestimations that may dilute focus on severe cases like state-imposed forced labor.

Founding and History

Establishment and Early Years

Walk Free was established in 2010 as an initiative of the Minderoo Foundation by Australian mining magnate and his daughter Grace Forrest, with the aim of addressing modern slavery through global advocacy and data-driven strategies. The organization's creation stemmed from Grace Forrest's firsthand exposure to human exploitation during her time working at a children's rescue home in , where she observed the pervasive impacts of trafficking and forced labor on vulnerable populations. This experience underscored the need for systemic interventions beyond immediate rescue efforts, prompting the Forrests to channel philanthropic resources toward eradicating slavery's root causes. In its formative phase, Walk Free operated as a division of the Hope for Children Organization Ltd., focusing on building partnerships and compiling evidence to quantify the scale of modern worldwide. By 2012, the foundation had formalized its launch, emphasizing collaboration with governments, businesses, and to foster policy reforms and corporate accountability. Early efforts prioritized awareness-raising, including public campaigns that highlighted 's estimated prevalence—later formalized in reports—and advocated for legislative measures, such as 's Modern Slavery Act, which drew on Walk Free's foundational research. The organization's initial milestone came in 2013 with the release of the inaugural , which estimated 29.8 million people living in conditions of modern across 162 countries, providing a benchmark for subsequent advocacy and revealing data gaps in underreported regions. This publication marked Walk Free's shift from inception to operational impact, leveraging empirical methodologies to challenge underestimations in international estimates and drive targeted interventions in high-prevalence areas like and .

Expansion and Affiliations

Walk Free has expanded its scope since its early years by broadening research coverage and forging international collaborations to enhance data accuracy and global advocacy. The organization's flagship (GSI), initially launched in 2013 with data from 162 countries, evolved through partnerships, including with Gallup for prevalence surveys, leading to expanded country studies reaching nearly 50 nations by 2018. By the 2023 GSI edition, estimates encompassed 160 countries, incorporating refined methodologies for vulnerability assessments and government responses. This growth reflects a shift from Australia-based origins to worldwide operations, including direct support for frontline liberation efforts and policy influence in regions like and . A pivotal expansion occurred through joint ventures with multilateral bodies; in 2017, Walk Free partnered with the (ILO) to research modern slavery scales, formalizing a tripartite collaboration with the ILO and (IOM) since 2016 for biennial Global Estimates reports. These alliances have enabled comprehensive prevalence modeling, estimating 50 million people in modern slavery globally as of 2021, up from prior figures, while addressing methodological critiques by integrating labor and migration data. Additional growth involved sector-specific initiatives, such as the 2022-2023 Faith For Freedom App training with church networks in and , amplifying grassroots anti-slavery efforts. Walk Free maintains affiliations with diverse entities to leverage expertise in eradication efforts, including NGOs like the Freedom Fund and , with whom it co-launched a 2014 Worldwide Directory of Modern Slavery Organizations to connect service providers and policymakers. Faith-based partnerships under the Global Freedom Network include Ghana, utilizing over 400 church partners for trafficking prevention training, and the Inter-Religious Council of Kenya for advocacy workshops and faith leader federations targeting eradication by 2024. Other key collaborators encompass Survivor Alliance for lived-experience expert groups in regions like , alongside platforms such as WikiRate for corporate accountability and Freedom United for campaigns; these ties span governments, businesses, and academia to promote legislation and supply chain transparency.

Funding and Operations

Walk Free is primarily funded by the Minderoo Foundation, a philanthropic entity established by Australian mining magnate and his wife Nicola Forrest, who co-founded the organization alongside their daughter Grace Forrest in 2010. The Minderoo Foundation serves as Walk Free's principal backer, describing it as the organization's flagship program and providing independent, privately sourced financial support without reliance on public grants or funding as primary mechanisms. This structure enables operational autonomy, though specific annual budgets or detailed financial disclosures are not publicly available, consistent with privately funded nonprofits. Operationally, Walk Free functions as an international organization headquartered in , , with a multidisciplinary team comprising statisticians, criminologists, lawyers, and development specialists. Its activities center on research-driven initiatives, such as producing the through and estimation methodologies, alongside advocacy to influence and corporate practices. The group engages stakeholders including governments, businesses, faith-based networks (via the Global Freedom Network), and civil society organizations, often through partnerships like the co-founding of the Freedom Fund in 2013 to support anti-slavery programs in high-prevalence regions. Direct investments target frontline interventions, transparency, and survivor-led efforts, emphasizing systemic change over isolated projects. As of recent assessments, the organization maintains a lean structure focused on evidence-based agitation for policy reforms and global data dissemination, without disclosed expansion into multiple international offices.

Mission and Conceptual Framework

Core Objectives

Walk Free's primary objective is the eradication of modern slavery in all its forms within a single generation. This encompasses , , , and , with an emphasis on addressing root causes through systemic reforms rather than isolated interventions. The organization pursues this by generating empirical data via tools like the , which estimates prevalence across 160 countries, informing targeted actions to reduce the estimated 50 million people affected globally as of 2021. Central to its framework are three interconnected pillars: strengthening governmental and international systems, rendering modern slavery socially unacceptable, and eliminating it from global s. Under systems strengthening, Walk Free advocates for legislative accountability, pushing governments to enact and enforce anti-slavery laws while protecting vulnerable populations through policy influence and partnerships with entities like the . The social unacceptability pillar targets cultural norms and discrimination—such as and ethnic biases—that perpetuate , employing to shift public and institutional attitudes. Finally, supply chain eradication focuses on corporate responsibility, promoting and to uncover and remediate hidden abuses in industries from to . These objectives integrate , , and direct engagement, mobilizing businesses, faith leaders, and to amplify impact. Walk Free emphasizes evidence-based strategies, critiquing superficial responses in favor of multifaceted approaches that address both and factors, such as and weak . While self-reported as comprehensive, the organization's metrics prioritize estimates over causal verification, relying on surveys and administrative data to guide global efforts.

Definition of Modern Slavery

Walk Free defines modern slavery as situations of exploitation that a person cannot refuse or leave because of threats, , , , and/or . This conceptualization serves as an umbrella term encompassing multiple forms of severe , drawing on legal frameworks such as the , the 1956 Supplementary Convention on the Abolition of Slavery, the UN Protocol to Prevent, Suppress and Punish Trafficking in Persons (Palermo Protocol), and (ILO) conventions including No. 29 (, 1930), No. 105 (Abolition of , 1957), and No. 182 (Worst Forms of , 1999). Key categories under this definition include , defined as work exacted under the menace of any penalty and not offered voluntarily; , involving the recruitment, transportation, or harboring of persons for through coercion or deception; , where labor is pledged as security for a that cannot be fairly repaid; , entered without full consent often under duress; and slavery-like practices, entailing exercise of powers attaching to ownership or control over a person; and the worst forms of , such as child trafficking, sexual , or hazardous work akin to . State-imposed is also included when it violates ILO standards, though Walk Free emphasizes private-sector in global supply chains, industries like and manufacturing, and domestic settings. Unlike historical slavery, which involved formal legal of individuals as , modern lacks explicit but achieves similar outcomes through psychological and physical control mechanisms, rendering unable to without significant risk. This definition prioritizes the of over strict legal , aligning with efforts to estimate in reports like the , where modern is operationalized primarily through indicators of (including trafficking and ) and , estimated at 49.6 million people globally as of 2021 data analyzed in collaboration with the ILO and .

Major Initiatives

Global Slavery Index

The (GSI) is Walk Free's primary tool for quantifying modern slavery worldwide, first published in 2013 as an inaugural report ranking 162 countries by estimated prevalence rates per 1,000 population. The index combines data from household surveys, survivor testimonies, and statistical modeling to estimate the number of people in forced labor or , aiming to highlight hotspots, track trends, and pressure governments for action. Subsequent editions followed in 2014 and 2016, with the most recent in 2023 covering prevalence estimates for 160 countries and government response evaluations for 176. The GSI's core metric is prevalence, disaggregating modern slavery into forced labor (including private and state-imposed forms) and , with country-level figures derived from direct surveys where available and extrapolated models elsewhere. It also features a model identifying risk factors such as conflict, governance failures, , and discrimination, which ranked as the most vulnerable nation in the 2023 edition. A government response index, introduced in later editions, scores nations on prevention, prosecution, and protection efforts, revealing stalled progress globally since 2018, with only three countries enacting mandatory laws by 2021. The 2023 GSI estimated 49.6 million people living in modern on any given day in 2021, equivalent to one in 150 individuals worldwide and a 10 million increase from 2016 estimates, attributed to rising conflict, climate impacts, and exploitation. Country rankings placed highest in at 104.6 per 1,000, followed by and , while aggregating data underscored and the Pacific as hosting over half of cases, with (11 million) and (5.8 million) topping absolute numbers. nations imported $468 billion in goods at risk of modern in 2021, linking consumption to . These figures, while influential in , rely on modeled extrapolations from patchy primary data sources like Walk Free's surveys in select countries.

Other Reports and Campaigns

Walk Free has developed the Modern Slavery Benchmarking Tool, an online resource enabling organizations to anonymously evaluate their management of modern slavery risks across operations and supply chains, offering performance scores and tailored improvement recommendations aligned with statutory requirements such as the and Modern Slavery Acts. The Promising Practices initiative, established in 2015, curates a global database of programmatic evaluations and impact assessments for anti-slavery interventions, synthesizing evidence on effective approaches including survivor inclusion, cash transfers, and counter-trafficking measures to inform policy and practice. In collaboration with the Initiative, Walk Free released the "Eradicating Modern Slavery" report on July 30, 2020, evaluating progress by 49 governments toward UN Sustainable Development Goal Target 8.7, which aims to end modern slavery by 2030; it documented insufficient coordinated action, weak survivor support, and gaps in , urging enhanced cross-border accountability mechanisms. Additional reports target sector-specific and investor-focused challenges. "Modern Slavery & Remediation: An Investor’s Guide," co-produced with the First Sentier Sustainable Investment Institute, outlines strategies for financial actors to support victim remediation in portfolios. "Beyond Compliance in the Sector," developed with Wikirate, analyzed disclosures from 108 electronics firms under modern slavery laws, identifying persistent gaps in risk mitigation and . " and Modern Slavery," jointly authored with , examines how environmental disruptions exacerbate slavery vulnerabilities, providing guidance for to integrate these risks into decision-making. Walk Free's campaigns emphasize accountability and norm-shifting, including drives to render modern slavery socially unacceptable through activist mobilization and business toolkit dissemination, such as the Modern Slavery Business & Investor Toolkit promoting benchmarking and .

Methodological Approach

Data Collection and Estimation Techniques

Walk Free primarily relies on nationally representative household surveys conducted in collaboration with the (ILO) and the (IOM) to collect data on modern slavery prevalence. These include 68 surveys focused on and 75 on , administered through the Gallup World Poll from 2017 to 2021, covering over 77,914 direct respondents across dozens of countries and incorporating network sampling to reach an estimated 628,598 individuals for capturing hidden . Surveys employ standardized questionnaires to identify experiences of (e.g., economy ) and , with responses adjusted for underreporting common in clandestine activities. Administrative data supplements survey findings, particularly from the Counter Trafficking Data Collaborative (CTDC), an anonymized dataset aggregating case records from IOM and partner organizations on trafficking victims receiving protection services, which informs estimates of . Secondary sources, such as ILO Committee of Experts reports on state-imposed , provide validated inputs for specific forms of not fully captured by surveys. United Nations population estimates are then applied to derive per-capita prevalence rates. For countries with direct survey data, estimates calculate as a stock measure by combining reported flows of with average duration, yielding point-in-time figures. In the absence of surveys—covering most of the 160 countries in the —imputation models generate predictions using weighted linear regressions incorporating geographic variables, statistics, and subregional averages to fill gaps. Advanced risk modeling employs Bayesian hierarchical multi-level models to assess vulnerability, integrating individual-level factors (e.g., , , ) with country-level indicators to predict exploitation probabilities and apportion regional totals to unsurveyed nations. Multiple imputation techniques address missing respondent data within surveys, ensuring robustness, though the approach acknowledges limitations in detecting covert due to reliance on self-reporting and modeled extrapolations.

Vulnerability Assessments

Walk Free's vulnerability assessments form a component of the (GSI), evaluating the risk factors that heighten susceptibility to modern across 160 countries. The model, updated iteratively with input from expert working groups, draws on and theories to quantify structural and systemic drivers of . It produces a composite score ranging from 1 to 100, where higher values indicate greater , derived from secondary data sources such as UNHCR, indicators, and UN datasets as of December 31, 2021. This assessment complements prevalence estimates by identifying predictive risk factors rather than directly measuring incidents. The model organizes 23 variables into five primary dimensions: issues (e.g., political instability, levels, and absence of political ); lack of (e.g., undernourishment rates and access to ); (e.g., for income disparity and indices); disenfranchised groups (e.g., prevalence of minorities, migrants, and against specific ethnic or social groups); and effects of (e.g., internal and to ). Each variable is normalized to a 1-100 , with inverted to reflect heightened (e.g., low access scores higher for vulnerability). Dimension scores are computed as eigenvalue-weighted averages of their constituent variables, then aggregated into an overall country-level vulnerability score via simple averaging. Missing data, which affects coverage in data-scarce regions, is imputed using subregional averages, with thresholds ensuring reliability (e.g., at least 50% data completeness for most dimensions). For the 2023 GSI, six variables were substituted from the 2018 model due to discontinued datasets, such as replacing certain metrics with updated and indicators, improving data availability but reducing direct comparability with prior editions. The model's aims include informing prevalence adjustments, prioritizing targets (e.g., conflict zones like scoring 86 on vulnerability), and flagging research gaps in under-surveyed areas. Empirical validation through statistical testing links these factors to observed prevalence, though reliance on aggregated limits for subnational risks.

Criticisms and Controversies

Methodological Flaws

Critics have identified several flaws in the Global Slavery Index's (GSI) data collection methods, primarily its dependence on small-scale, non-representative surveys conducted in only a handful of countries, which are then extrapolated to estimate prevalence across 148 nations. For instance, the GSI drew from surveys in seven countries and from nine others, yet applied these findings broadly without robust sampling to account for cultural, economic, or legal variations, resulting in unstable estimates such as Brazil's ranging from 45,006 to over 1 million before settling on 155,300. Estimation techniques in the GSI involve crude clustering of countries into six groups based on factors like and , leading to illogical equivalences, such as assigning identical prevalence rates to and despite stark differences in , , and patterns. Similarly, South Africa's figures were derived by weighting 70% toward patterns and 30% toward ones due to perceived cultural similarities, a method lacking empirical validation and introducing arbitrary assumptions. The GSI's modeling remains opaque, with limited on how survey responses—often from fragile samples—are adjusted for underreporting or combined with secondary sources of varying quality, contributing to inflated global estimates like the 2016 figure of 45.8 million, which exceeds the Labour Organization's contemporaneous forced labor estimate of 20.9 million by more than double. Country-specific critiques highlight this, such as India's 14.3 million estimate, questioned for relying on poor-quality without , and Mauritania's 4% prevalence rate, presented as high without corroborating beyond modeling. Methodological inconsistencies persist across GSI editions, including annual changes to the "modern slavery" definition without clear justification, undermining comparability; for example, early versions rejected certain national data (e.g., from the , , and ) after external challenges, yet retained unverified extrapolations for large nations like by proxying it against , , and . These issues collectively compromise the index's reliability, as noted by experts who argue the approach prioritizes headline figures over rigorous, verifiable quantification.

Conceptual and Definitional Issues

Walk Free employs a broad definition of modern slavery, describing it as "situations of exploitation that a person cannot refuse or leave because of threats, , , deception, or abuse of power or position," encompassing , , , , and other slavery-like practices. This framework draws from international legal standards such as those in the and the 1930 but extends them into an umbrella concept without a singular binding legal definition in global law. Critics contend that this expansiveness conflates historically distinct phenomena, such as with contemporary issues like or hazardous child labor, thereby diluting analytical precision and equating varying degrees of and agency loss. A primary definitional challenge arises from the inclusion of , which Walk Free estimates contributes substantially to global prevalence figures—often comprising over half of calculated cases in certain regions—yet lacks uniform evidence of the severe control akin to traditional . Scholars argue this risks framing cultural or familial arrangements as equivalent to exploitative enslavement without sufficient differentiation, potentially inflating estimates and complicating targeted interventions. For instance, the definition's reliance on subjective inability to "refuse or leave" may capture social pressures or economic dependencies not rooted in direct , blurring lines between and poverty-driven choices. Further issues stem from the definition's evolution across Global Slavery Index editions, with alterations in scope—such as varying emphases on deception or child soldiering—undermining consistency and comparability over time. This self-constructed approach, while intended to highlight hidden abuses, has been faulted for selective application, omitting structurally coerced labor in contexts like or penal systems in high-income nations, which exhibit parallels in restricted freedom yet evade classification as "." Such exclusions raise questions of conceptual equity, as the framework prioritizes individual perpetrator-victim dynamics over broader systemic vulnerabilities like state policies or economic inequalities.

Responses and Defenses

Walk Free Foundation representatives have addressed criticisms of the (GSI) by highlighting the inherent difficulties in quantifying a concealed and underreported phenomenon, while committing to iterative enhancements in and analysis. In a January response published in , Fiona David, then Executive Director of Global Research at Walk Free, affirmed that GSI estimates, such as the 29.8 million people in modern slavery worldwide from the 2013 edition, rely on secondary sources, limited surveys, and expert inputs due to the absence of comprehensive primary . She concurred with critics like Neil Howard on the risks of overdependence on secondary , advocating for expanded primary to better capture both scale and drivers, such as agricultural subsidies and trade policies. To counter methodological concerns, Walk Free has emphasized and ongoing refinements, including the of random sample surveys, rigorous controls for secondary sources, and strengthened evaluations of responses. Subsequent GSI iterations reflect these adjustments; for instance, the 2016 edition introduced detailed methodological appendices outlining modeling via Bayesian hierarchical approaches to account for data scarcity and variability across countries. By the 2023 GSI, the incorporated data from over 50 national household surveys covering approximately 55,000 respondents, supplemented by administrative records and expert consultations, to generate country-level estimates with confidence intervals acknowledging . Regarding conceptual and definitional critiques, Walk Free defends its broad framing of modern slavery—encompassing , , , and trafficking—as aligned with international instruments like the , the 1930 , and the 2000 Palermo Protocol, arguing that a unified metric facilitates cross-national comparisons and policy focus despite definitional ambiguities in law. The organization maintains that vulnerability assessments, derived from factors like conflict, , and weak legal frameworks, empirically correlate with higher prevalence rates, as validated through analyses in GSI reports showing statistical associations (e.g., a 10% increase in vulnerability scores linked to elevated slavery estimates). Collaborations, such as with the for the 2017 global estimates of 40.3 million in modern slavery, further bolster claims of robustness by harmonizing GSI data with ILO's forced labor surveys. Walk Free positions the GSI not as definitive but as a catalytic for , urging critics to contribute for refinement rather than dismissal, with public release of datasets and models to enable independent verification. Supporters, including statisticians like Bernard Silverman, have praised the vulnerability modeling for identifying causal correlates of , such as failures, though they note persistent challenges in from . Despite these defenses, Walk Free acknowledges that estimates remain approximations, with no claim to in absolute numbers, prioritizing directional insights for intervention over exactitude.

Impact and Evaluation

Policy and Legislative Influence

Walk Free has actively lobbied globally to enact laws targeting modern slavery, emphasizing , victim support, and criminal justice reforms. Their advocacy often leverages data from the to highlight prevalence and governmental shortcomings, urging adoption of national action plans aligned with UN Goal Target 8.7. In , Walk Free contributed to the passage of the Modern Slavery Act 2018, which mandates large businesses to report on slavery risks in supply chains, by publishing a 2017 policy paper titled "The Case for an Australian Modern Slavery Act" that outlined regulatory gaps and international benchmarks. The submitted recommendations during the Act's statutory review in 2022, advocating for stronger enforcement mechanisms like mandatory . Walk Free has also engaged with UK policymakers on the Modern Slavery Act 2015, providing evidence to parliamentary inquiries in 2024 on improving victim protections and addressing non-compliance in corporate statements, while collaborating on tools to assess under the law. Their research, including analyses of over 1,000 statements, has informed calls for mandatory due diligence. Internationally, Walk Free's efforts supported the European Union's Corporate Sustainability Due Diligence Directive (adopted in 2024), which requires companies to identify and mitigate forced labor risks in operations and supply chains, through joint advocacy with partners. The organization claims the has driven such reforms by providing empirical benchmarks, though independent verification of causal impact remains limited to self-reported engagements and policy citations.

Empirical Outcomes and Challenges

The (GSI), Walk Free's flagship publication, has documented a rise in estimated modern slavery prevalence since its inception, with figures increasing from approximately 40 million people in 2016 to 50 million in 2021, equating to roughly one in 150 individuals worldwide. This upward trend persists despite heightened global awareness and Walk Free's advocacy, as corroborated by joint estimates from the , Walk Free, and the , which attribute the growth to factors like , , and economic shocks rather than successful interventions. No independent empirical studies directly attribute reductions in slavery prevalence to the GSI or Walk Free's efforts, and the organization's own data indicate stagnation or deterioration in high-risk regions such as and the Arab States. Walk Free's work has correlated with policy advancements, including the enactment of modern slavery legislation in countries like the (2015) and (2018), which mandate corporate reporting on risks, as well as criminalization of in 50 governments and forced labor in 87 countries by 2023. These measures, influenced by GSI rankings and , have prompted actions such as Uzbekistan's eradication of state-imposed forced labor in 2021, leading to lifted international boycotts, and kafala system reforms in like and to enhance migrant worker mobility. However, evaluations of these laws reveal limited empirical effectiveness; for instance, analyses of UK and modern slavery statements show superficial corporate compliance, with few verifiable reductions in at-risk imports— nations imported $468 billion in goods linked to modern slavery risks in 2021, including electronics and garments—suggesting that transparency requirements have not substantially disrupted exploitative s. Key challenges include the inherent difficulties in empirically verifying modern slavery due to its clandestine nature, reliance on small-scale surveys and indirect estimates in the GSI , which critics argue conflates distinct phenomena like forced labor and without robust causal linkages or longitudinal tracking of interventions. response scores in the 2023 GSI average below 50% globally, with persistent state-imposed forced labor in 17 countries (e.g., , ) and inadequate survivor support in 15 nations, compounded by corruption and weak enforcement that undermine policy gains. External pressures, such as the and conflicts in and , have exacerbated vulnerabilities without corresponding scalable countermeasures, highlighting gaps in Walk Free's model for translating data into measurable declines. Only four countries have implemented mandatory laws by 2023, limiting broader .
