Counties That Make Up the Tulsa Metro Area

The Tulsa metro area is defined by a specific set of Oklahoma counties that function together as a regional economic, governmental, and planning unit. Understanding which counties are included — and why — matters for everything from federal funding allocation to regional transportation planning and census-based demographic reporting. This page identifies each constituent county, explains how inclusion boundaries are determined, and contrasts the two primary frameworks used to define the metro's geographic scope.

Definition and scope

The Tulsa metropolitan area is officially delineated through two overlapping but distinct federal frameworks. The first is the Metropolitan Statistical Area (MSA), defined by the U.S. Office of Management and Budget (OMB) using commuting-pattern data and core urban population thresholds (OMB Bulletin No. 23-01). The second is the Combined Statistical Area (CSA), which links adjacent MSAs and micropolitan areas sharing measurable economic ties.

Under the OMB's 2023 delineation, the Tulsa, OK Metropolitan Statistical Area consists of 6 counties:

  1. Tulsa County — the core county, containing the city of Tulsa and the majority of the metro's population
  2. Creek County — located west of Tulsa, anchored by Sapulpa
  3. Osage County — north of Tulsa, largely rural with the city of Pawhuska as county seat
  4. Rogers County — northeast of Tulsa, containing Claremore and growing residential communities
  5. Wagoner County — east of Tulsa, including Wagoner and Coweta
  6. Okmulgee County — south of Tulsa, centered on Okmulgee city

Each of these counties qualifies under OMB criteria because a statistically significant share of their working residents commute to or from the Tulsa urban core, creating a functionally unified labor market. Detailed population figures for each county are available through the Tulsa Metro Population and Demographics reference.

How it works

County inclusion in the MSA is not determined by municipal boundary lines, regional preferences, or state legislative action. The OMB applies a standardized commuting-flow methodology drawing on U.S. Census Bureau American Community Survey data. A county qualifies for MSA inclusion when at least 25 percent of its resident workers commute to the core urban area, or when at least 25 percent of the core area's workers commute outward into that county (U.S. Census Bureau, Metropolitan and Micropolitan Statistical Area Standards).

Tulsa County anchors the entire MSA designation because it contains the principal city (Tulsa) and holds a population exceeding the 50,000-resident threshold required to qualify as a metropolitan statistical area. The remaining 5 counties are termed outlying counties in federal terminology — included based on commuting ties rather than population density alone.

OMB revisits MSA boundaries after each decennial census and may adjust county composition when commuting patterns shift. The 2023 bulletin, for example, reflects commuting data drawn from the 2020 Census and subsequent American Community Survey waves.

For regional planning purposes, the Indian Nations Council of Governments (INCOG) — the metropolitan planning organization for the Tulsa area — operates across a planning boundary that largely mirrors but is not identical to the OMB MSA. INCOG's transportation planning area incorporates parts of counties based on anticipated urbanization corridors, not solely current commuting flows (INCOG, Regional Transportation Plan).

Common scenarios

Three practical situations illustrate why the county composition of the Tulsa MSA matters beyond academic geography.

Federal grant eligibility — U.S. Department of Housing and Urban Development (HUD) programs, including Community Development Block Grants and HOME Investment Partnerships, calculate eligibility thresholds and per-capita allocations using MSA county boundaries. A municipality in Rogers County or Wagoner County qualifies for different funding pools than an equivalent-sized city outside the MSA entirely.

Economic and workforce reporting — The Bureau of Labor Statistics (BLS) reports unemployment rates, wage data, and employment-by-industry figures at the MSA level. Businesses and policymakers comparing the Tulsa labor market to peer metros are implicitly comparing all 6 MSA counties together, not Tulsa County alone. This aggregation can mask significant variation: Okmulgee County, for instance, has a substantially different employment base than Rogers County.

Real estate and housing market analysis — Lenders, appraisers, and housing agencies use MSA boundaries to determine conforming loan limits set annually by the Federal Housing Finance Agency (FHFA). A home in Creek County falls under Tulsa MSA limits rather than the lower limits that would apply in a non-metro Oklahoma county. The Tulsa Metro Housing Market page covers how these limits function in practice.

Decision boundaries

Two contrast points clarify where the Tulsa MSA ends and adjacent designations begin.

MSA vs. CSA — The Tulsa MSA (6 counties) is a subset of the larger Tulsa-Muskogee-Bartlesville, OK Combined Statistical Area, which adds the Bartlesville MSA (Washington County) and the Muskogee MSA (Muskogee and McIntosh counties). The CSA is used for broader regional economic analysis but does not determine HUD or BLS metro-level reporting. Washington County and Muskogee County are therefore sometimes described as part of the "greater Tulsa region" in colloquial usage, but they fall outside the 6-county MSA for federal program purposes.

MSA vs. City Limits — Tulsa city limits do not extend across all of Tulsa County, much less across all 6 MSA counties. The incorporated city of Tulsa occupies approximately 201 square miles within Tulsa County (City of Tulsa GIS data). The full MSA spans thousands of square miles, encompassing dozens of independent municipalities. The Tulsa Metro Cities and Municipalities reference lists those incorporated places by county.
