Industry Density & Geographic Rollups | NAICS & SIC Counts by Geography

Updated: 2026

Category: Applied Data Services & Use Cases

Industry Density & Geographic Rollups provide pre-aggregated counts and rollups by geography and industry level (NAICS and/or SIC). These files are built for heatmaps, whitespace modeling, territory planning, site selection, and portfolio analytics.

What industry density files include

Density files summarize the number of establishments in an industry within a defined geographic unit. They are designed for fast analysis without requiring every establishment-level record.

  • Industry key: NAICS (2–6 digit) and/or SIC (2–4 digit), plus industry title.
  • Geographic key: state, county, metro/CBSA, ZIP (scope-based).
  • Counts: establishment counts per industry/geography combination.
  • Rollups: optional rollups from detailed codes to higher-level categories (sector/subsector).
  • Documentation: data dictionary and delivery notes for consistent interpretation.

Supported geographies

Geographic layers can be provided at different resolutions depending on your mapping needs and analysis workflow.

Common geographic layers

  • State: fast macro comparisons and regional reporting
  • County: density maps and market sizing
  • CBSA/Metro: comparable markets and metro rollups
  • ZIP: local planning and target overlays (scope-based)

How teams use these layers

  • GIS heatmaps: map density by county/ZIP
  • Site selection: compare trade areas with standardized categories
  • Territory planning: align sales regions to market density
  • Portfolio segmentation: benchmark exposure by metro/region

Industry rollup levels (NAICS/SIC)

Rollups allow your analytics and mapping tools to display industry density at multiple levels, from high-level sectors to detailed industries.

System Levels commonly delivered Why it matters
NAICS 2, 3, 4, 5, 6 digit (scope-based) Sector-level views plus drill-down to detailed segments
SIC 2, 3, 4 digit (scope-based) Legacy reporting continuity and historical comparisons
Crosswalk (optional) NAICS ↔ SIC mapping references Bridge datasets across legacy systems and modern analytics

File formats (built for GIS & analytics)

Analyst-friendly formats

Useful for BI tools, spreadsheets, and quick internal analysis.

  • CSV
  • Excel
  • Documentation notes + data dictionary

Pipeline-friendly outputs

Useful for ingestion into warehouses, GIS stacks, and scheduled refresh processes.

  • Structured files suitable for ETL
  • Consistent keys and field naming
  • Version labeling for governance

Common enterprise use cases

  • GIS heatmaps: show industry concentration by county/metro/ZIP.
  • Whitespace models: identify under-served areas by category density and region.
  • Site selection: benchmark candidate locations against comparable markets.
  • Territory planning: align sales regions to industry presence and segment concentration.
  • Portfolio exposure: quantify the industry makeup of a geographic footprint.
  • Market sizing: estimate addressable market using standard code buckets.

Example schemas (representative)

Your final schema is defined during scoping. Below are representative examples used by GIS and analytics teams.

Example: County density (NAICS)

state_fips
county_fips
county_name
naics_2 / naics_3 / naics_4 / naics_5 / naics_6
industry_title
establishment_count
report_year
dataset_version

Example: Metro/CBSA density (rollups)

cbsa_code
cbsa_name
naics_level (2–6)
naics_code
industry_title
establishment_count
rollup_path (sector → subsector → group → industry)
report_year
dataset_version

QA & governance alignment

Density files are most useful when they are consistent, well-documented, and easy to reconcile across refresh cycles.

  • Consistent keys: stable geography keys and industry codes for repeatable joins.
  • Hierarchy-aware rollups: sector/subsector rollups reduce ambiguity in dashboards.
  • Documentation included: data dictionary + version notes to support governance.

FAQ

  • What’s the difference between density files and establishment-level files?
    Density files provide aggregated counts by geography and industry. Establishment-level files provide record-level locations. Density is best for mapping and market sizing; establishment-level is best for enrichment and detailed record workflows.
  • Can we get rollups at multiple NAICS levels?
    Yes. Many teams request NAICS 2–6 level rollups so dashboards can switch between sector views and detailed industries.
  • Which geography level should we use for heatmaps?
    County and CBSA are common for market sizing and comparable regions; ZIP is common for local planning. The best choice depends on your use case and performance requirements.
  • Do you support SIC rollups too?
    Yes. SIC rollups can be included for legacy continuity and comparative reporting.
  • Do you provide a data dictionary?
    Yes. Enterprise deliveries include field definitions and documentation notes.
  • Is this the same as a marketing list?
    No. Density files are aggregated analytics outputs. If you need outreach lists, see Business Lists.
