Urban ethnographers study underground street economies and informal housing markets primarily through long-term, immersive fieldwork. Rather than relying only on surveys or official records—which often miss informal or illegal activities—they spend months or years building relationships, observing daily life, and combining multiple sources of evidence to understand how these systems actually function.
Here are the main approaches they use:
Participant observation
The hallmark of ethnography is living in or regularly spending time in the community. Researchers might:
- Rent a room in or near an informal settlement.
- Spend time in markets, transit hubs, community centers, or public gathering places.
- Observe how people negotiate work, housing, and disputes.
- Accompany residents through their daily routines, when appropriate and with consent.
This allows them to see practices that people might not mention in interviews.
In-depth interviews
Researchers conduct open-ended conversations with a wide range of people, including:
- Residents
- Informal landlords
- Tenants
- Street vendors
- Waste pickers
- Transport workers
- Community leaders
- NGO staff
- Local government officials
- Police (when relevant)
Instead of asking only "What do you do?", they often ask about life histories, migration, housing decisions, income strategies, and social networks.
Mapping informal systems
Because many transactions leave no official record, ethnographers create their own maps documenting:
- Rental arrangements
- Housing subdivisions
- Vendor locations
- Transportation routes
- Water and electricity access
- Social and economic relationships
Today this may involve GPS, participatory mapping with residents, or GIS alongside hand-drawn maps.
Social network analysis
Many underground economies depend on trust rather than formal contracts. Ethnographers therefore document:
- Who introduces newcomers to jobs
- How credit is extended
- How disputes are resolved
- Kinship and migration networks
- Patron-client relationships
The emphasis is often on relationships rather than individual actors.
Following transactions
Researchers sometimes "follow the money" or "follow the commodity." For example, they may trace:
- How a market stall is obtained
- How informal rent is collected
- Where recycled materials are sold
- How goods move through informal supply chains
This reveals economic structures that are largely invisible in official statistics.
Triangulation
Because information about informal or illicit activities can be incomplete or strategically presented, ethnographers compare multiple sources:
- Interviews
- Direct observations
- Government records
- Satellite imagery
- NGO reports
- Historical documents
- Census data (where available)
Agreement across different kinds of evidence strengthens confidence in findings.
Studying underground street economies
Researchers recognize that "underground" can encompass a broad range of activities—from unlicensed but tolerated commerce to clearly illegal markets. They typically distinguish among these rather than treating them as a single category.
They may investigate:
- Street vending
- Informal transportation
- Day labor markets
- Recycling and scrap collection
- Home-based manufacturing
- Informal childcare
- Unlicensed repair services
When studying illegal markets, ethnographers generally avoid encouraging or participating in crimes. Instead, they focus on:
- Economic organization
- Governance structures
- Risk management
- Relationships with state authorities
- Residents' perspectives
Many rely on observations, interviews, and publicly observable interactions rather than direct involvement.
Studying informal housing markets
Informal housing markets are often sophisticated despite lacking formal legal recognition.
Researchers examine questions such as:
- How are plots allocated?
- Who is recognized locally as having authority?
- How is rent determined?
- What counts as proof of ownership?
- How are evictions carried out?
- How are homes inherited or transferred?
They often discover that informal settlements have their own rules, contracts, dispute resolution systems, and property norms, even when these are not recognized by the state.
Ethical considerations
Studying vulnerable populations and informal or illegal activities requires careful ethical practice. Researchers typically:
- Obtain informed consent appropriate to the context.
- Protect participants' identities through anonymization or pseudonyms.
- Avoid collecting unnecessary identifying information.
- Consider whether publishing certain details could increase risks for participants.
- Avoid actions that could expose residents to eviction, arrest, or retaliation.
Institutional ethics review boards often require detailed protocols for managing these risks.
Common challenges
Urban ethnographers face several methodological challenges:
- Building trust can take many months.
- People may conceal sensitive activities.
- Researchers' presence can influence behavior.
- Findings from one neighborhood may not generalize to another.
- Political conditions, policing, or redevelopment can rapidly change the setting.
For these reasons, many studies combine ethnography with surveys, spatial analysis, archival research, or economic data.
Strengths and limitations
Strengths
- Reveals everyday practices invisible in official data.
- Explains why informal institutions emerge and persist.
- Captures the perspectives of residents.
- Provides rich context for policy and theory.
Limitations
- Time-intensive and expensive.
- Usually involves relatively small samples.
- Findings may not be statistically representative.
- Access to hidden or dangerous settings may be limited.
Overall, ethnography is particularly valuable for understanding how informal economies and housing markets function in practice: how trust is established, how disputes are resolved, how resources circulate, and how residents navigate life in environments where formal legal and economic institutions may be incomplete, inaccessible, or only one part of the governing landscape.
