# Market Research Source Guide

## Purpose

This recipe produces a prioritized map of data sources matched to your specific industry and data needs, with quality scores, cost estimates, and step-by-step access instructions. The output eliminates the most common market sizing bottleneck: knowing where to look. A startup founder should be able to go from "I need market data" to "I have 5 usable data points" in under 2 hours using this guide.

## Prerequisites

- [ ] **Target industry or market segment** identified
- [ ] **Specific data needs** listed (market size, growth rate, customer count, pricing, etc.)
- [ ] **Budget determined** (free, modest, or professional)
- [ ] **Web browser access** for accessing databases and platforms

## Constraints

- Free government data (Census, BLS, SEC) is authoritative but lagged 6-18 months behind current conditions. Use for structural data (market size, customer counts), not for trend analysis. [src2]
- No single source covers all industries. Budget for 3-5 sources minimum to cross-reference and validate. [src1]
- Report summaries and press release excerpts are not substitutes for full methodology sections. Key assumptions and definitions are often behind paywalls. [src4]
- International market data quality varies dramatically by country. US and EU data is most reliable; emerging market data often has wide confidence intervals. [src5]
- AI-generated market reports (increasingly common) may recycle outdated data or hallucinate numbers. Always verify the primary data source behind any statistic. [src3]

## Tool Selection Decision

```
Which path?
├── Need US market data
│   └── PATH A: Government First — Census, BLS, SEC, SBA, FRED
├── Need global/international market data
│   └── PATH B: International — World Bank, OECD, UN, Eurostat
├── Need technology/SaaS market data
│   └── PATH C: Tech-Focused — Gartner, IDC, Statista, CB Insights
└── Need consumer/retail market data
    └── PATH D: Consumer — Nielsen, Euromonitor, Census Retail
```

| Path | Tools | Cost | Speed | Output Quality |
|------|-------|------|-------|---------------|
| A: US Government | Census, BLS, SEC, FRED | $0 | 1-2 hours | High (authoritative but lagged) |
| B: International | World Bank, OECD, Eurostat | $0 | 1-2 hours | Medium-high (varies by country) |
| C: Tech-Focused | Gartner, Statista, CB Insights | $0-500/mo | 1-3 hours | High (current but expensive) |
| D: Consumer | Nielsen, Euromonitor, Census | $0-1000/mo | 1-3 hours | High |

## Execution Flow

### Step 1: Identify Required Data Points

**Duration**: 15 minutes
**Tool**: Text editor

Define exactly what data you need before searching:

```json
{
  "data_requirements": [
    {"data_point": "Total market revenue", "priority": "critical", "found": false, "source": null},
    {"data_point": "Market growth rate (CAGR)", "priority": "critical", "found": false, "source": null},
    {"data_point": "Number of potential customers", "priority": "critical", "found": false, "source": null},
    {"data_point": "Average revenue per customer", "priority": "high", "found": false, "source": null},
    {"data_point": "Market segmentation breakdown", "priority": "high", "found": false, "source": null},
    {"data_point": "Geographic distribution", "priority": "medium", "found": false, "source": null},
    {"data_point": "Competitor market share", "priority": "medium", "found": false, "source": null},
    {"data_point": "Customer demographics/firmographics", "priority": "medium", "found": false, "source": null}
  ]
}
```

**Verify**: At least 3 "critical" data points identified
**If failed**: If you cannot define what you need, revisit market boundary definition in the market sizing recipe.

### Step 2: Search Free Government Sources

**Duration**: 30 minutes
**Tool**: Web browser

Start with free, authoritative sources before spending money:

**US Census Bureau** (https://data.census.gov)
- Best for: Business counts by industry (NAICS), employee size, geography
- Search: County Business Patterns (CBP), Statistics of US Businesses (SUSB)
- Quality: Authoritative, lag 12-18 months
- Use: Bottom-up customer count estimates

**Bureau of Labor Statistics** (https://www.bls.gov)
- Best for: Employment data, wage data, industry output, price indices
- Search: Quarterly Census of Employment and Wages (QCEW), CPI
- Quality: Authoritative, lag 6-12 months
- Use: Labor market sizing, salary benchmarks, inflation adjustment

**SEC EDGAR** (https://www.sec.gov/cgi-bin/browse-edgar)
- Best for: Public company financials, industry segments, revenue breakdowns
- Search: 10-K filings (annual) and 10-Q filings (quarterly) by SIC code
- Quality: Authoritative, current to last filing
- Use: Competitor revenue, market share estimation, industry trends from MD&A sections

**Federal Reserve (FRED)** (https://fred.stlouisfed.org)
- Best for: Economic indicators, GDP by sector, interest rates, monetary data
- Quality: Authoritative, frequently updated
- Use: Macro context for market sizing

**SBA / Trade.gov** (https://www.sba.gov/business-guide/plan-your-business/market-research-competitive-analysis)
- Best for: Small business statistics, export data, industry overviews
- Quality: Authoritative, curated for entrepreneurs
- Use: SMB market sizing, industry overviews

**Verify**: At least 2 critical data points found from government sources
**If failed**: Move to paid sources. Some industries (especially emerging tech) have limited government coverage.

### Step 3: Search Free Non-Government Sources

**Duration**: 20 minutes
**Tool**: Web browser

**Google Trends** (https://trends.google.com)
- Best for: Search interest trends, seasonal patterns, geographic distribution
- Quality: Relative (not absolute numbers), good for directional trends
- Use: Demand trend validation, geographic opportunity

**Crunchbase Free** (https://www.crunchbase.com)
- Best for: Startup funding data, company counts, investor activity
- Quality: High for VC-backed companies, incomplete for bootstrapped
- Use: Competitor funding, industry investment trends

**App Annie / Sensor Tower Free Reports**
- Best for: Mobile app market data, download estimates
- Quality: Estimates (not exact), good for mobile markets
- Use: App market sizing, download benchmarks

**Industry Associations**
- Search: "{industry} association report" or "{industry} trade group statistics"
- Best for: Industry-specific metrics, member surveys, annual reports
- Quality: Varies; often the most specific data available for niche markets
- Use: Industry benchmarks, market size from trade group perspective

**Academic Papers** (Google Scholar: https://scholar.google.com)
- Search: "{industry} market size" OR "{industry} market analysis"
- Best for: Rigorous methodology, detailed data in appendices
- Quality: High (peer-reviewed) but often 1-3 years behind
- Use: Cross-validation of market size estimates

**Verify**: Source tracker updated with all found data points and their sources
**If failed**: If free sources are insufficient, proceed to paid sources.

### Step 4: Evaluate and Access Paid Sources (If Needed)

**Duration**: 20 minutes
**Tool**: Web browser

**Tier 1: Budget ($39-100/month)**

| Source | URL | Best For | Cost | Quality |
|--------|-----|----------|------|---------|
| Statista | statista.com | Cross-industry statistics, infographics | $39-79/mo | High (aggregates from 22,000+ sources) |
| SimilarWeb Free/Basic | similarweb.com | Website traffic, digital market share | Free-$149/mo | Medium-high (estimates) |
| Google Market Finder | marketfinder.thinkwithgoogle.com | International market opportunity | Free | Medium |

**Tier 2: Professional ($200-500/month)**

| Source | URL | Best For | Cost | Quality |
|--------|-----|----------|------|---------|
| IBISWorld | ibisworld.com | Industry reports by NAICS code | $300-500/mo | Very high (human-verified) |
| CB Insights | cbinsights.com | Tech/startup market intelligence | $288/mo+ | High (tech-focused) |
| Crunchbase Pro | crunchbase.com/pro | Startup data, funding, company search | $49/mo | High (VC-backed companies) |

**Tier 3: Enterprise ($1,000+/month)**

| Source | URL | Best For | Cost | Quality |
|--------|-----|----------|------|---------|
| Gartner | gartner.com | Technology market forecasts | $30K+/yr | Very high (authoritative) |
| IDC | idc.com | IT market sizing and forecasts | Custom pricing | Very high |
| Euromonitor | euromonitor.com | Consumer goods, retail | $1,500+/mo | Very high |
| PitchBook | pitchbook.com | PE/VC, M&A, company valuations | Custom pricing | Very high |

**Verify**: At least one paid source identified that fills gaps from free sources
**If failed**: If budget is zero, focus on government sources + creative proxy approaches (see error handling).

### Step 5: Quality-Score and Cross-Reference

**Duration**: 15 minutes
**Tool**: Spreadsheet

Rate each data point on a 1-5 quality scale:

```json
{
  "quality_criteria": [
    {"criterion": "Source authority", "description": "Government/academic = 5, major research firm = 4, trade publication = 3, blog/estimate = 2, unknown = 1"},
    {"criterion": "Recency", "description": "2026 = 5, 2025 = 4, 2024 = 3, 2023 = 2, older = 1"},
    {"criterion": "Methodology transparency", "description": "Full methodology disclosed = 5, summary = 3, none = 1"},
    {"criterion": "Specificity", "description": "Exact match to your market = 5, close proxy = 3, broad industry = 1"},
    {"criterion": "Corroboration", "description": "Confirmed by 3+ sources = 5, 2 sources = 3, single source = 1"}
  ]
}
```

Average quality score per data point. Prioritize data scoring >= 3.0. Flag anything below 2.5 as unreliable.

**Output files**:
- `research_source_map.json` — All sources with quality scores and access details
- `data_collection_plan.md` — Step-by-step plan for gathering each required data point

## Output Schema

```json
{
  "output_type": "research_source_map",
  "format": "JSON",
  "columns": [
    {"name": "data_point", "type": "string", "description": "What data is needed", "required": true},
    {"name": "source_name", "type": "string", "description": "Data source name", "required": true},
    {"name": "source_url", "type": "string", "description": "Direct URL to data", "required": true},
    {"name": "cost", "type": "string", "description": "Cost to access", "required": true},
    {"name": "quality_score", "type": "number", "description": "Quality rating 1-5", "required": true},
    {"name": "value_found", "type": "string", "description": "Actual data value extracted", "required": false},
    {"name": "date_of_data", "type": "string", "description": "When data was published/collected", "required": true}
  ],
  "expected_row_count": "8-20",
  "sort_order": "quality_score descending",
  "deduplication_key": "data_point + source_name"
}
```

## Quality Benchmarks

| Quality Metric | Minimum Acceptable | Good | Excellent |
|---------------|-------------------|------|-----------|
| Critical data points found | >= 2/3 | 3/3 | 3/3 with cross-validation |
| Average source quality score | >= 2.5 | >= 3.5 | >= 4.0 |
| Sources per data point | >= 1 | >= 2 | >= 3 (triangulated) |
| Data recency | 2023+ | 2024+ | 2025-2026 |

**If below minimum**: For niche markets, use proxy approaches: adjacent industry data + adjustment factors, LinkedIn company count as proxy for customer base, public company revenue as market share baseline.

## Error Handling

| Error | Likely Cause | Recovery Action |
|-------|-------------|----------------|
| No market size report exists | Market too new or niche | Use bottom-up proxy: count companies on LinkedIn/Crunchbase, multiply by estimated spend |
| Data behind paywall | Research firm monetization | Check if your local library offers database access (many universities provide IBISWorld, Statista) |
| Conflicting data from different sources | Different market definitions | Check each source's definition of the market boundary; align to yours |
| Data is 3+ years old | Slow-moving industry or niche | Apply industry growth rate to bring forward; note the extrapolation and confidence decrease |
| Government data uses different categories | NAICS codes don't match your segment | Use the closest NAICS code and apply a percentage estimate for your sub-segment |

## Cost Breakdown

| Component | Free Tier | Paid Tier | At Scale |
|-----------|-----------|-----------|----------|
| Government databases | $0 | $0 | $0 |
| Google Trends/Scholar | $0 | $0 | $0 |
| Statista | $0 (limited) | $39-79/mo | $79/mo |
| IBISWorld | $0 (library access) | $300-500/mo | $500/mo |
| Crunchbase | $0 (limited) | $49/mo | $49/mo |
| **Total monthly** | **$0** | **$39-528** | **$49-629** |

## Anti-Patterns

### Wrong: Citing a single market report as the definitive market size
Every research firm uses different methodologies and definitions. Citing one report without cross-validation is building on a single point of failure. If that report's methodology doesn't match your market definition, your entire sizing is off. [src1]

### Correct: Triangulate from 3+ sources
Use government data as a structural baseline, industry reports for growth context, and your own bottom-up count for specificity. Report the range, not a single number.

### Wrong: Using AI-generated market size estimates without verifying primary sources
AI tools increasingly generate market size numbers that may be outdated, hallucinated, or recycled from unreliable sources. If you cannot trace a number back to a named source with a publication date, do not use it. [src3]

### Correct: Always trace to primary source
For every market size number, record: source name, publication date, URL, and methodology summary. If you cannot provide these four elements, the number is not usable.

## When This Matters

Use at the start of any market sizing project or competitive analysis. This recipe saves 3-5 hours of trial-and-error searching by mapping the right sources to the right data needs upfront. Particularly valuable for first-time founders who may not know that Census Bureau SUSB data exists or that university libraries provide free access to IBISWorld.
