Applying TAM, SAM, and SOM to the Indiana emergency responder training center concept:

1. TAM (Total Addressable Market)
This is the maximum potential market size—all organizations in Indiana that could benefit from emergency responder training at centers like ESEC and similar facilities.

  • Includes: Every fire department, EMS provider organization, law enforcement agency, public safety department, and related entities statewide.
  • Approximate scope:
    • 367 EMS provider organizations3
    • Hundreds of fire departments (volunteer, paid, combination)3
    • Law enforcement agencies and other public safety bodies (state, local, federal)2
    • Relevant volunteer agencies, towing services, public works, and National Guard units5
    • Private sector organizations requiring certification (e.g., security, healthcare, industrial safety teams)7

This encompasses thousands of organizations and many thousands of individual responders across Indiana.

2. SAM (Serviceable Available/Addressable Market)
This is the segment of TAM realistically served by the Indiana-based facility, considering its regional location, infrastructure, and focus.

  • Includes:
    • Agencies within feasible geographic reach (e.g., within a few hours’ drive of central Indiana)
    • Organizations that need services ESEC provides (live fire, EMS, CPAT, SWAT, etc.)1
    • Agencies whose schedules and needs align with ESEC/IDHS/partner offerings12
  • Likely scope:
    • Central Indiana and surrounding counties’ fire, EMS, and police agencies, plus regional organizations that can travel to Indianapolis.
    • School systems, colleges, and adult learners within the region exploring public safety careers1.

3. SOM (Serviceable Obtainable Market)
This is the portion of SAM the facility can realistically serve in the near term—factoring in competition, partnerships, and operational capacity.

  • Includes:
    • Agencies and individuals already training at ESEC or similar Indiana centers1 (program participant data)
    • Those actively marketed to, or under contract/memorandum with the center
    • Realistic growth targets based on staff, space, and logistics limitations
  • Typical scope:
    • Hundreds to a few thousand trainees per year, depending on class sizes, frequency, and facility scale (exact numbers would require ESEC annual reports or state aggregation)
    • Likely a subset of active agencies prioritizing ongoing skills development and proximity

Summary Table

Market LevelDefinitionIndiana Application Example
TAMAll organizations that could ever benefit from the offeringAll IN public safety (EMS, fire, law, etc.) agencies
SAMThose realistically reachable/fit by the service/facilityAgencies within <~2 hrs of Indy with training needs
SOMRealistically obtainable/served segment now or soonActual ESEC/partner trainees per year

In sum:

  • TAM is all Indiana-based potential clients
  • SAM is those the facility can currently target due to location/focus
  • SOM is those who actively use, or are projected to use, the Indiana facilities now or soon

This segmentation helps size the market and set strategic, attainable goals for growth and funding.

Here are actual, current estimates for fire, EMS, law enforcement, and emergency service entities in Indiana based on the latest reporting and official surveys:

EMS Provider Organizations

  • 367 EMS provider organizations with distinct primary operating addresses are currently operating and certified in Indiana6.
  • These include:
    • Volunteer fire departments (EMS-certified): 34.1% (125 organizations)
    • Paid fire departments (EMS-certified): 19.5% (72 organizations)
    • Combination fire departments (EMS-certified): Remainder of total (exact number not specified, but majority falls within fire department categories)6.

Fire Departments (Total)

  • According to the National Fire Department Registry, there are approximately 800-900 registered fire departments in Indiana (2023 data, USFA/FEMA)1.
  • Of these, a significant percentage are also EMS providers, per above.

Police/Law Enforcement Agencies

  • Indiana has approximately 450 law enforcement agencies. This includes:
    • Indiana State Police
    • County sheriff offices (92 counties)
    • Numerous municipal police departments
    • University, airport, and specialty forces
      This figure is widely referenced in public safety datasets; exact current numbers may vary slightly.

Natural Disaster & Emergency Relief Services

  • 32 organizations classified specifically as “Natural Disaster & Emergency Relief Services,” with a market size of $191.2 million in Indiana5.

Other Entities

  • National Guard: Indiana has an active National Guard contingent with approximately 65 armories and training sites statewide.
  • Federal Agencies: Multiple federal law enforcement and response entities (FBI, DEA, etc.) maintain offices and operational units in Indiana, though each only operates a small number of facilities or offices in the state.

Applying TAM–SAM–SOM

  • TAM: Would encompass all organizations above (nearly 1,200–1,400 agencies/entities statewide, not counting private sector and specialty industrial response teams).
  • SAM: Those within realistic travel distance, relevant operational focus, or aligned training needs—likely a subset of several hundred.
  • SOM: The actual number of agencies/entities currently served or realistically projected to train at the facility annually—typically in the dozens to low hundreds, depending on class frequency, facility size, and outreach.

If you need even more specific breakdowns (e.g., number of paid vs. volunteer fire departments, EMS-only vs. dual fire/EMS agencies, etc.), those can be provided from source details16.
