Research Methodology

Overview

World Adult Guide covers 90+ countries with detailed information on legal frameworks, pricing, safety, health, and cultural norms. This page explains, in concrete terms, how that information is gathered, verified, and kept current. We publish this methodology because we believe our readers have a right to understand exactly how we arrive at the claims we make.

For our broader editorial principles, see our Editorial Standards page. This page focuses specifically on research methods and data handling.

How Pricing Data Is Collected and Verified

Pricing is among the most frequently requested and most difficult-to-verify categories of data we handle. Our approach is multi-source and conservative:

• Published rate cards — In regulated markets (Germany, Netherlands, New Zealand, parts of Australia), many venues and licensed providers publish their rates openly. These are our most reliable pricing data points.
• Community surveys — We aggregate anonymized self-reported pricing data from our community contributors. Individual reports are not treated as authoritative, but patterns across multiple independent reports establish reliable ranges.
• Forum data — We monitor established online communities where pricing is discussed. This data is treated as secondary and used to corroborate, not establish, pricing ranges.
• Economic indexing — We track local economic indicators (average wages, cost of living indices, currency exchange rates) to sanity-check pricing data. If reported prices are wildly inconsistent with local economics, we flag them for additional verification.
• Provider feedback — In jurisdictions where it is legal and appropriate, we accept direct feedback from providers about prevailing market rates. Provider input is weighted alongside other sources, not treated as definitive on its own.

All pricing is presented as ranges, never exact figures. We include the currency, the date of last verification, and any caveats (tourist pricing vs. local rates, high-season vs. low-season variation, urban vs. rural differences).

Source Types and Reliability Hierarchy

We categorize sources into tiers based on reliability:

Tier 1 — Official and Institutional Sources

These are the highest-authority sources and form the foundation for legal and health claims:

• National criminal codes and statutory texts
• Government regulatory publications and official gazettes
• World Health Organization (WHO) guidelines and data
• U.S. Centers for Disease Control and Prevention (CDC) publications
• UNAIDS reports and data
• Peer-reviewed academic journals
• Court rulings and official legal interpretations

Tier 2 — Established Advocacy and Research Organizations

• Amnesty International policy research
• New Zealand Prostitutes' Collective (NZPC)
• Sex Workers Outreach Project (SWOP)
• Global Network of Sex Work Projects (NSWP)
• Human Rights Watch reports
• Government travel advisories (U.S. State Department, UK FCDO, Australian DFAT)

Tier 3 — Community and Observational Sources

• First-hand contributor observations
• Community-reported data (aggregated and cross-referenced)
• Forum discussions (corroborative use only)
• Provider self-reports
• News reporting from reputable outlets

Tier 3 sources are never used alone to establish a factual claim. They are used to identify potential updates, corroborate higher-tier sources, and add practical context that institutional sources may lack.

Data Freshness Policy

Different types of data have different staleness thresholds:

• Legal information — Considered stale if not verified within the past 6 months or if a legislative event has occurred in the jurisdiction since last review. Legal information is monitored continuously.
• Pricing data — Considered stale if not verified within the past 6 months. In jurisdictions with volatile currencies or rapid inflation, the threshold is reduced to 3 months.
• Health and safety information — Considered stale if not aligned with the most recent guidelines from WHO, CDC, or the relevant national health authority. Reviewed at minimum quarterly.
• Cultural and practical information — Considered stale if not verified within the past 12 months. This category includes venue descriptions, neighborhood information, and practical logistics.
• Emergency contacts and hotlines — Verified every 3 months. Non-functional numbers are removed or replaced immediately upon discovery.

When data exceeds its freshness threshold, the page is flagged for priority review. If the review cannot be completed quickly, a staleness notice is displayed to readers.

Geographic Coverage Approach

Not all 90+ countries we cover receive the same depth of coverage, and we want to be transparent about why:

• Depth correlates with data availability — Countries with legal, regulated industries (Germany, Netherlands, New Zealand) have more data available and therefore receive more detailed coverage.
• Reader demand influences priority — Countries that are more frequently searched and visited receive more frequent updates and deeper analysis.
• Contributor access matters — Countries where our contributors have first-hand experience receive richer practical detail than countries covered primarily through institutional sources.
• Safety considerations — In some jurisdictions, gathering on-the-ground information carries personal risk. We do not ask contributors to put themselves in danger, which means coverage of certain countries relies more heavily on institutional and community sources.
• Language access — Countries where our team can read local-language sources in the original receive more nuanced coverage than countries where we depend on translations.

We are actively working to expand coverage depth across all regions. If you can contribute reliable information about an underserved country, please contact us.

Provider Perspective Inclusion

We believe our content is more accurate and more ethical when it includes the perspectives of sex workers themselves. We actively seek provider input in several ways:

• We reference publications and statements from sex worker advocacy organizations (NZPC, SWOP, NSWP, and national-level organizations).
• We maintain a dedicated For Providers section with 28 resources written with provider input and reviewed by provider advocates.
• Our Provider Perspective guide and Provider Interviews present first-person accounts and insights.
• Provider feedback on our content is prioritized in our review process — if a provider says our description of their market is wrong, we investigate immediately.

Bias Awareness and Mitigation

We acknowledge that all research carries inherent biases, and we take active steps to identify and mitigate ours:

• Client-perspective bias — Much of our community data comes from clients rather than providers. We counterbalance this by actively seeking provider perspectives and weighting provider-advocacy sources highly in our editorial process.
• English-language bias — Our team's strongest language is English, which means English-language sources may be overrepresented. We mitigate this through multilingual team members and professional translation of key non-English sources.
• Western-perspective bias — Our editorial team's personal experience is weighted toward Western and Southeast Asian markets. We acknowledge this and actively seek contributors with expertise in underrepresented regions.
• Survivorship bias in community data — Community contributors who share positive experiences may be overrepresented compared to those who had negative experiences and prefer not to discuss them. We account for this by supplementing community data with safety reports and advocacy organization data.
• Confirmation bias — To guard against confirming our own assumptions, our fact-checking process requires actively seeking disconfirming evidence before a claim is published.
• Selection bias in coverage — Countries with more available data and more contributor access receive deeper coverage. We are transparent about this (see Geographic Coverage above) and actively work to reduce coverage gaps.

How We Handle Conflicting Information

Conflicting information is common in our subject area, and we have established protocols for handling it:

• Official vs. practical reality — When official law and enforcement practice diverge (for example, when sex work is technically illegal but openly tolerated), we present both the legal status and the enforcement reality, clearly distinguishing between the two.
• Competing sources — When two credible sources disagree on a factual claim, we investigate the discrepancy. If we cannot resolve it, we present both positions and explain the conflict to the reader.
• Pricing discrepancies — When reported prices vary significantly, we widen our stated range and note the variability. We investigate whether the discrepancy reflects genuine market variation (different neighborhoods, different service levels) or whether one source is outdated.
• Cultural interpretation differences — When cultural practices or norms are interpreted differently by different sources, we prioritize local perspectives over outside interpretations, and we acknowledge that cultural practices are not monolithic.

Quality Metrics

We track several internal metrics to measure and improve the quality of our research:

• Correction rate — We track how often reader-reported corrections are verified as valid. A high correction rate would indicate a systemic research failure. We aim for and maintain a low correction rate.
• Review timeliness — We track whether quarterly reviews are completed on schedule. Delayed reviews are flagged and the affected content carries a freshness warning.
• Source diversity — We monitor the diversity of sources cited across the site. Over-reliance on any single source or source type is flagged for attention.
• Coverage completeness — We track which countries and topics have the deepest coverage and where gaps exist, to prioritize expansion efforts.
• Reader feedback patterns — We analyze the types of corrections and feedback we receive to identify systemic weaknesses in our research process.

Limitations and Disclaimers

Intellectual honesty requires us to be clear about what we cannot guarantee:

• We are not omniscient — Conditions change rapidly. Despite our best efforts, some information may be outdated between review cycles. Always verify critical information (especially legal status and safety conditions) through local sources before acting on it.
• We cannot verify everything — Some claims, particularly about conditions in countries with limited press freedom or restricted information environments, cannot be fully verified through our standard process. We note these limitations transparently.
• Pricing is inherently approximate — Prices vary by location, time, provider, and circumstances. Our ranges are guides, not guarantees.
• Legal information is not legal advice — Our legal summaries are informational. Laws are complex, enforcement varies, and only a qualified attorney in the relevant jurisdiction can provide legal advice for your specific situation.
• Health information is not medical advice — We present health information from authoritative medical sources, but we are not healthcare providers. Consult a medical professional for personal health decisions.
• Individual experiences will vary — Our information describes general patterns and conditions. Your individual experience may differ based on factors we cannot predict or account for.
• Underground markets are inherently opaque — In jurisdictions where sex work is criminalized, gathering reliable information is significantly harder. Our coverage of these markets relies more heavily on advocacy organization reports and community data, and we are transparent about the resulting limitations.

We would rather admit what we do not know than present uncertain information as fact. Transparency about our limitations is itself a form of quality assurance — it helps readers calibrate the appropriate level of trust for each piece of information.
