Overview
Every occupation has a geographic footprint. Some spread broadly across the country—think administrative assistants or retail salespeople—while others concentrate in specific regions due to industry presence, historical development, or natural resources.
This employment concentration tool reveals these patterns by calculating each state’s share of total national employment for any occupation. When California holds 12% of software developer jobs but only 11% of all jobs, you’re seeing industry clustering in action.
Why does this matter? Because:
- Recruiting in high-concentration states gives you access to more candidates but puts you in direct competition with more employers seeking the same skills.
- Expanding to lower-concentration states may offer less competition but requires building awareness and potentially relocating workers.
- Investment and site selection decisions benefit from understanding where proven talent pipelines already exist.
Understanding employment clusters
What creates concentration?
Industry clustering happens for several interconnected reasons:
Industry anchors. When major employers establish headquarters or operations in a state, they attract suppliers, partners, and talent—creating a reinforcing cycle. Detroit still concentrates automotive employment; Silicon Valley still anchors tech.
Education and training pipelines. States with strong university programs in specific fields develop local talent pools that employers tap.
Cost and regulatory environment. Business-friendly policies, lower costs, or specific incentives can shift employment over time—though these effects take years to materialize in occupation-level data.
Natural advantages. Resource extraction, agricultural conditions, or port access determine where certain industries locate.
Concentration vs. employment volume
A state can have high employment volume but low concentration if it’s a large state. California has the most software developers in raw numbers, but its share of national tech employment tells you whether the industry is especially clustered there relative to other occupations.
The tool shows both metrics: absolute employment counts and percentage share of national employment.
Strategic applications
Hiring strategy
In high-concentration states: Expect competitive recruiting. Candidates have options, so your employer brand, compensation, and growth opportunities need to stand out. You’ll find more specialized talent but pay premium wages.
In low-concentration states: You may find less competition for candidates, but the talent pool is smaller. Consider remote-friendly roles or building awareness campaigns to attract workers who want to stay local.
Expansion planning
If you’re opening a new office or manufacturing facility, employment concentration data shows where you’ll find trained workers ready to hire. A state with 5%+ of national employment in your target occupation has a proven workforce.
Competitive intelligence
Where are your competitors likely hiring? Industry concentration maps reveal the geographic battleground for talent. If 60% of your occupation’s workforce is in five states, those states see the most head-to-head recruiting competition.
How to use this data
Step 1 — Select your occupation and click to see concentration data.
Step 2 — Review the map grid. Darker colors indicate higher employment share. States with 5%+ share are major hubs.
Step 3 — Check the metrics. Note what share the top 5 and top 10 states hold combined. High concentration (50%+ in top 5) means clustered industry.
Step 4 — Examine the full table. Sort by employment or share to see rankings. Filter to compare specific states you’re considering.
Step 5 — Cross-reference with wages. High-concentration states may have higher wages due to competition. Use wage benchmarking tools for compensation context.
Step 6 — Apply to your decisions. For hiring, expansion, or market analysis, use concentration data alongside cost-of-living and business environment factors.
Methodology and limitations
Source: U.S. Bureau of Labor Statistics, Occupational Employment and Wage Statistics (OEWS).
Calculation: State employment ÷ national employment × 100 = percentage share of national employment.
Geography: All 50 states + District of Columbia. Metro-level variation exists within states.
What is included: Wage and salary workers in the occupation. Self-employed workers are excluded from OEWS.
What is not included: Part-time vs. full-time breakdown, contractor employment, or gig economy workers.
Timeliness: OEWS is released annually with a May reference period. The survey year is displayed in the tool.
FAQs
What does employment concentration mean?
Employment concentration measures what percentage of total national workers in an occupation are located in each state.
A state with 10% concentration holds 10% of all U.S. workers in that occupation.
Learn More...
Concentration is calculated by dividing state employment by national employment and multiplying by 100.
High concentration indicates industry clustering—where workers in specific occupations gather due to major employers, industry hubs, or regional specialization.
Why do some occupations cluster in certain states?
Industry anchors, education pipelines, historical development, and natural advantages create regional clusters.
Major employers attract talent and suppliers, creating self-reinforcing concentration over time.
Learn More...
Silicon Valley concentrates tech jobs because of early semiconductor and software company presence that attracted talent and investment.
Similarly, Houston concentrates energy sector jobs due to oil industry history and infrastructure.
These patterns persist because workers, companies, and training programs all benefit from proximity.
How should I interpret the color-coded map?
Darker blue states hold a larger share of national employment for the selected occupation.
States with over 5% share are major employment hubs for that occupation.
Learn More...
The legend shows five tiers: over 5% (darkest), 3-5%, 2-3%, 1-2%, and under 1% (lightest).
Compare your occupation's map to 'All Occupations' to see if your field is more or less concentrated than the general workforce.
What does it mean if the top 5 states hold over 50% of employment?
That occupation is highly concentrated—most workers cluster in a handful of states.
Recruiting and expansion for that occupation will focus on those key states.
Learn More...
High concentration (50%+ in top 5 states) is common for specialized industries like tech, finance, or energy.
Broad-based occupations like administrative assistants or retail workers typically show lower concentration because they're needed everywhere.
Concentration affects wage competition, talent availability, and employer strategy.
How can I use this data for hiring decisions?
High-concentration states offer larger talent pools but more competition for candidates.
Lower-concentration states may offer less recruiting competition but smaller candidate pipelines.
Learn More...
If you need to hire many workers in a specialized occupation, focus on high-concentration states where trained workers already live and work.
For remote roles, you can recruit from high-concentration states while the employee lives elsewhere.
Consider wage premiums in high-concentration areas versus potentially easier recruiting in lower-concentration markets.
Does high employment share mean higher wages?
Often, but not always. Concentration and wages are related but not perfectly correlated.
Competition for talent in concentrated markets can drive wages up.
Learn More...
States with high employment concentration often have multiple employers competing for workers, which can increase wages.
However, high concentration can also reflect lower-cost regions where industries relocated—in which case wages may be moderate despite high employment.
Use the wage data column in the tool to see the relationship for your specific occupation.
How often is the employment concentration data updated?
OEWS employment data is released annually with a May reference period.
The tool displays the current survey year in the footnotes.
Learn More...
BLS publishes new OEWS data each spring covering the previous May survey period.
Employment concentration patterns tend to be stable year-to-year, though gradual shifts occur as industries relocate or grow.
Can I compare concentration across different occupations?
Yes, run the tool for multiple occupations and compare which states dominate each field.
You'll see different geographic footprints for different industries.
Learn More...
Tech occupations concentrate on the coasts; healthcare is more evenly distributed; energy clusters in Texas and the Gulf.
Comparing occupations helps you understand regional specialization and plan multi-role hiring strategies.
In summary
Employment concentration reveals the hidden geography of industries. Some occupations cluster tightly in a few states; others spread broadly. Understanding these patterns helps you make smarter decisions about where to hire, where to expand, and where you’ll face the stiffest competition for talent.
Use this tool to map your occupation’s footprint, then combine insights with wage data and local business conditions for complete workforce planning.
