Key Findings

In Pictures

Five figures summarize the paper’s central descriptive findings: 30-year completion-volume trajectories across eleven professional programs; pooled long-run volume change; cross-program shifts in gender and race/ethnicity composition; and chiropractic institution-level variation in both overall demographic change and Black/Hispanic representation. Five-year pooled endpoint comparisons are used where annual values would overstate short-term volatility.

Figure 1. Annual practice-oriented completion volume across eleven U.S. health-profession degree programs, 1994–95 through 2024–25. Lines show annual IPEDS completions under the program-specific CIP6 and award-level definitions described in Methods and Appendix A; the legend is sorted by 2025 volume, with chiropractic highlighted in purple and physical therapy in orange. Chiropractic remained a comparatively small pipeline and, unlike most comparator programs, did not show sustained long-run expansion: annual completions rose in the late 1990s, declined through the 2000s and early 2010s, and subsequently recovered. Visualization was human generated.

Percent change is calculated from pooled completion counts for each professional program using the program-specific CIP6 and award-level definitions described in Methods and Appendix A. Chiropractic declined 20.4% and podiatry declined 8.2%; all nine other comparator programs increased, from 32.3% for MD medicine to 343.2% for physician assistant programs. Chiropractic is highlighted in purple and physical therapy in orange; other programs are shown in gray. Pooling five-year periods reduces sensitivity to single-year variation but does not eliminate differences in program structure or historical credential transitions.

The distribution shows broad movement toward higher female and non-White representation, with substantial institutional heterogeneity. Race/ethnicity results should be interpreted with institution-specific reporting coverage in mind. Visualization was human generated.

Dashed lines summarize the common-institution cohort: 2.8% Hispanic and 2.0% Black in 1995–99 versus 12.1% Hispanic and 5.8% Black in 2021–25; Panel B retains the earlier references in muted form. Institutions moved along different demographic pathways, with especially wide recent dispersion in Hispanic share. This denominator differs from the known-domestic race measure used elsewhere and should be interpreted alongside reporting completeness. Visualization was human generated.

Abstract

Background and objective. Demographic change in the practicing healthcare workforce reflects, in part, earlier changes in professional education. This study describes 30 years of U.S. health-profession completions and examines whether chiropractic’s changing demographic profile occurred within an expanding, stable, or contracting educational pipeline.

Methods. NCES Integrated Postsecondary Education Data System (IPEDS) Completions files were harmonized from academic year 1994–95 through 2024–25. Eleven practice-oriented health-profession program series were identified at the six-digit Classification of Instructional Programs level, with historical CIP and award-level crosswalks applied where credentials changed. Five-year pooled 1995–99 and 2021–25 periods were used for long-run comparisons. Race/ethnicity was harmonized across legacy, transition, and modern IPEDS reporting structures; long-run analyses compare White non-Hispanic with reported non-White among known domestic completers. Chiropractic institution-level analyses used historical IPEDS directory files to assess reporting-unit continuity.

Results. Chiropractic completions declined from 17,375 in 1995–99 to 13,825 in 2021–25 (−20.4%). Podiatric medicine was the only other comparator with a pooled decline (−8.2%); the other nine programs expanded 32.3% to 343.2%. At the same time, chiropractic female share increased from 27.9% to 46.0%, and reported non-White share among known domestic completers increased from 12.2% to 32.4%. All eleven programs became less White by the harmonized long-run measure. In chiropractic, Hispanic representation increased 8.6 percentage points from 2011–15 to 2021–25, the largest Hispanic increase among the eleven programs. All fourteen longstanding chiropractic institutions with endpoint data became more female and more non-White, but the magnitude and composition of change varied.

Conclusion. U.S. health-profession educational pipelines have broadly diversified, but their volume trajectories differ markedly. Chiropractic is notable not because demographic transition is unique to the profession, but because substantial demographic change occurred within a pipeline whose recent five-year completion volume remains materially below its late-1990s baseline. A shorter window beginning in the mid-2010s correctly identifies a recent rebound but does not characterize the full 30-year trajectory.

1. Background and Objective

A Workforce in Transition described the demographic structure of the current clinical workforce across fifteen healthcare professions and specialties, using CMS-enrolled clinician data and years since graduation to distinguish earlier- and later-career cohorts. That analysis showed broad movement toward greater female and racial/ethnic representation, including within chiropractic. The present study examines the upstream educational pipeline that precedes those workforce patterns.

Completions and workforce counts answer different questions. Workforce data describe the stock of clinicians currently participating in practice; education data describe awards emerging from professional programs. The latter can identify whether demographic transition is occurring broadly across educational pathways, whether completion volumes are expanding or contracting, and—within chiropractic—whether national change reflects broad movement across longstanding institutions or is concentrated in a small subset of schools.

The study is intentionally descriptive. It does not test why students select one profession over another, whether admissions standards or financing policies affect those choices, or whether demographic change is associated with professional economic returns. Those questions require additional data on applicants, admissions, tuition, debt, earnings, labor-market outcomes, and geography. The purpose here is to establish a reproducible longitudinal description of what changed.

A second objective is to place recent chiropractic completion trends in historical context. Analyses beginning around 2015 observe a modest increase in chiropractic completions. The longer IPEDS series makes it possible to determine whether that recent direction represents long-run expansion or a rebound from a lower point in a substantially different historical trajectory.

2. Methods

2.1 Data Source and Study Period

The analysis uses annual NCES Integrated Postsecondary Education Data System (IPEDS) Completions data files for academic years 1994–95 through 2024–25, together with selected IPEDS institutional directory files for chiropractic reporting-unit lineage. The 31 annual completion cohorts span 30 years. The series begins with 1994–95 because the immediately preceding file structure does not support the same six-digit CIP-level race/ethnicity analysis required for this study.

Where both original and revised Completions files were available in the source archive, the revised file was used. The 2024–25 file was treated as provisional. All source archives, member filenames, release choices, and schema classifications are retained in the reproducibility workbook.

2.2 Program Identification and Primary-Major Rule

Programs were identified using six-digit Classification of Instructional Programs (CIP) codes. The analytic set comprises chiropractic, physical therapy, physician assistant, occupational therapy, optometry, podiatric medicine, dentistry, medicine (MD), osteopathic medicine (DO), pharmacy, and veterinary medicine. Chiropractic and physical therapy are the focal programs; the remaining programs provide professional-education context rather than a claim of clinical equivalence.

The analysis uses the first or primary major where IPEDS reports multiple-major fields (MAJORNUM=1). For earlier file structures in which second majors were stored separately, the A-file series was used as the primary-major source.

2.3 CIP and Award-Level Harmonization

The six-digit CIP codes for chiropractic, physical therapy, occupational therapy, optometry, dentistry, medicine, and pharmacy are stable across most or all of the period. Explicit crosswalks were applied for physician assistant programs (51.0807 to 51.0912), podiatric medicine (51.2101 to 51.1203), osteopathic medicine (51.1901 to 51.1202), and veterinary medicine (51.2401 to 01.8001).

Professional award classifications also changed. For chiropractic and other clean professional-practice series, legacy first-professional degree code 10 is used through 2006–07, codes 10 and 18 are included during the 2007–08/2008–09 transition, and doctor’s degree—professional practice code 18 is used from 2009–10 onward. Physical therapy and occupational therapy require broader practice-oriented proxies that follow historical bachelor-to-master-to-doctoral transitions. Physician assistant and pharmacy series likewise use explicit historical award-level rules. These proxy definitions are disclosed in Appendix A and should not be interpreted as perfectly invariant credentials over three decades.

2.4 Race/Ethnicity Harmonization

IPEDS race/ethnicity reporting changed during the study period. For 1994–95 through 2006–07, the analysis uses the legacy five-category structure plus race/ethnicity unknown and nonresident. For 2007–08 through 2009–10, NCES selected-category bridge variables are used to support comparability while institutions transitioned between reporting systems. From 2010–11 through 2024–25, the modern IPEDS categories are used. Asian and Native Hawaiian/Other Pacific Islander are additionally combined into a harmonized Asian/Pacific Islander category for the long series; the modern-period analysis preserves them separately.

The primary long-run race/ethnicity measure is reported non-White share among known domestic completers. The denominator is total completions minus nonresident completions and race/ethnicity-unknown completions. This avoids classifying unknown or international students as members of a U.S. racial/ethnic group and avoids artificially back-casting the modern Two or More Races category into years when it was not separately reported.

2.5 Gender Measure

Female share is calculated from the IPEDS counts reported as women and men. Historical IPEDS files do not provide a longitudinal nonbinary gender category; accordingly, this measure reflects the binary reporting structure in the source data and should not be interpreted as a complete measure of gender identity.

2.6 Chiropractic Institution Lineage

Institution-level analysis uses UNITID as the reporting identifier and incorporates directory snapshots from 1995–96, 2003, 2010, 2011, 2015, 2020, and 2025. Twenty-two UNITIDs reported positive chiropractic professional-entry completions at some point in the series. Most longstanding programs retain stable UNITIDs despite name changes. Four historical reporting units required special treatment, including the former Palmer West/San Jose UNITID, which disappears after 2010 even though the campus did not close at that time. The study therefore treats UNITID disappearance as a reporting-unit event unless independently supported as an institutional closure.

The principal chiropractic institution comparison is restricted to fourteen institutions with positive professional-entry completions in both pooled endpoint periods, 1995–99 and 2021–25. Five-year pooling reduces annual volatility. Race/ethnicity reporting coverage is calculated as known-race domestic completers divided by domestic completers, and institution-level interpretations are flagged where recent coverage is below 90%.

2.7 Descriptive Analysis

Annual completion counts describe the full 1994–95 to 2024–25 trajectory. Five-year pooled 1995–99 and 2021–25 periods provide the primary long-run comparisons for completion volume, female share, and harmonized reported non-White share. Modern-category race/ethnicity changes compare pooled 2011–15 with 2021–25. Results are descriptive; no causal models or inferential significance tests are used.

3. Results

3.1 Chiropractic Completion Volume: Recent Recovery Within a Lower Long-Run Baseline

The chiropractic completion series follows a pronounced long-run cycle rather than a simple growth trend. Annual professional-entry completions were 2,968 in 1994–95, increased through the late 1990s, and peaked at 3,809 in 1999–2000. Volume then declined substantially, reaching a low of 2,219 in 2012–13. Completions subsequently recovered to 3,022 in 2024–25 (Figure 1).

The choice of time window therefore changes the apparent direction of the trend. From 2014–15 to 2024–25, chiropractic completions increased from 2,544 to 3,022, an 18.8% increase. A recent-period analysis beginning around 2015 would correctly characterize the direction as modest expansion. In contrast, the five-year pooled comparison shows 17,375 completions in 1995–99 versus 13,825 in 2021–25, a 20.4% decline. Both findings are true: the recent period is a recovery from a lower-volume decade, while the contemporary pipeline remains smaller than the late-1990s pipeline when measured using pooled endpoints.

3.2 Completion-Volume Change Across Professional Programs

Completion-volume trajectories differed markedly across the eleven programs (Figure 2). Chiropractic (−20.4%) and podiatric medicine (−8.2%) were the only programs with fewer pooled practice-oriented completions in 2021–25 than in 1995–99. The other nine programs expanded: medicine (MD) +32.3%, optometry +36.7%, veterinary medicine +62.8%, pharmacy +65.1%, physical therapy +67.0%, dentistry +73.9%, occupational therapy +102.4%, osteopathic medicine +301.6%, and physician assistant +343.2%.

The comparison should be interpreted as a program-level descriptive contrast, not as a direct estimate of workforce supply. Award definitions differ across professions and historical credential transitions are especially important for physical therapy, occupational therapy, physician assistant, and pharmacy. Nonetheless, the magnitude and direction of change distinguish chiropractic’s long-run completion trajectory from most of the comparator set.

3.3 Gender Composition

Female representation increased in ten of eleven professional pipelines between 1995–99 and 2021–25 (Figure 3A). Chiropractic increased by 18.1 percentage points, from 27.9% to 46.0%. The largest increases were observed for physician assistant (+20.9 points), chiropractic (+18.1), dentistry (+17.8), veterinary medicine (+16.3), podiatric medicine (+16.1), and optometry (+15.9).

Physical therapy was the single exception: female share declined from 67.9% to 62.8% (−5.1 points), while remaining majority female. In the recent pooled period, female share ranged from 46.0% in chiropractic and 46.3% in podiatric medicine to 90.6% in occupational therapy. The data therefore show broad feminization across historically male-dominated professional programs, but no convergence to a common gender composition.

3.4 Race/Ethnicity Composition

All eleven professional pipelines became less White among known domestic completers using the harmonized long-run measure (Figure 3B). Chiropractic reported non-White share increased by 20.2 percentage points, from 12.2% in 1995–99 to 32.4% in 2021–25. The change was comparable to physical therapy (+19.5), optometry (+20.0), pharmacy (+21.6), and osteopathic medicine (+21.8), and smaller than podiatric medicine (+27.0).

This result is important for interpretation: demographic diversification is not a chiropractic-specific phenomenon. It is visible across every professional education pipeline examined. Chiropractic becomes distinctive when the demographic transition is considered together with completion volume: substantial diversification occurred while pooled completions remained below the late-1990s baseline.

3.5 Modern Race/Ethnicity Detail

The modern IPEDS reporting era allows more granular group-specific comparisons. From 2011–15 to 2021–25, chiropractic White share among known domestic completers decreased 12.9 percentage points, from 80.4% to 67.6%. Hispanic share increased 8.6 points, from 5.6% to 14.2%; Black share increased 1.8 points, from 4.9% to 6.6%; Two or More Races increased 1.9 points; Asian share increased 0.5 points. Native Hawaiian/Pacific Islander and American Indian/Alaska Native shares changed little.

The racial/ethnic pathways differ across professions. Chiropractic had the largest Hispanic-share increase in the comparator set over this modern-period comparison. Podiatric medicine had the largest Asian-share increase (+11.4 points), while pharmacy had the largest Black-share increase (+2.8 points). These differences reinforce the value of examining the component groups rather than treating all demographic change as a single non-White category.

3.6 Chiropractic Institutional Change Was Broad but Heterogeneous

Fourteen chiropractic institutions reported professional-entry completions in both pooled endpoint periods. All fourteen became more female and more non-White among known domestic completers (Figures 4A–B). Female-share increases ranged from 12.7 to 23.3 percentage points. Reported non-White-share increases ranged from 6.3 to 32.1 points. The common direction across longstanding institutions indicates that national demographic change was not produced solely by the entry of a small number of newer programs.

The composition of that change varied considerably (Figures 5A–B). Life University had the largest increase in Black share (+11.4 points) and also a large increase in Hispanic share (+17.9). Sherman College of Chiropractic had the largest Hispanic increase (+20.6), followed by Southern California University of Health Sciences (+19.8); Parker University increased 7.7 points in Black share and 13.1 points in Hispanic share. Texas Chiropractic College increased 5.7 points in Hispanic share and 2.9 points in Black share, but its recent race-reporting coverage was approximately 85%, warranting caution about the magnitude.

Reporting completeness is a substantive limitation for institutional comparisons. Northwestern Health Sciences University had only 47.7% recent race/ethnicity coverage among domestic completers in the pooled period, and several other institutions were below 90%. The manuscript therefore avoids rank-order claims about absolute diversity levels and emphasizes within-institution directional change, together with explicit coverage flags.

4. Discussion

4.1 Diversification Is Broad; Volume Change Is Not

The central cross-profession finding is a combination of common demographic direction and very different pipeline growth. Every program became less White among known domestic completers, and ten of eleven became more female. Demographic transition therefore appears to be a broad feature of U.S. professional education rather than a phenomenon unique to chiropractic.

Completion volume is different. Most comparator programs expanded substantially, with especially large growth in physician assistant and osteopathic medicine programs. Chiropractic and podiatric medicine were the only two series below their 1995–99 pooled completion volume in 2021–25. Chiropractic’s distinctive feature in this analysis is therefore the coexistence of broad demographic change with a smaller long-run completion pipeline.

4.2 Recent Growth and Long-Run Contraction Are Both True

The 30-year series changes the interpretation of recent chiropractic completion growth. From 2014–15 to 2024–25, annual completions increased 18.8%, a real recovery that is visible in Figure 1. Yet 2021–25 pooled completions remain 20.4% below 1995–99. The apparent tension is a function of the comparison window: the mid-2010s followed a prolonged decline and include the series trough.

This finding warrants reconciliation with Arete’s recent Educational ROI analysis, which used a more recent completion window and therefore observed modest expansion. A shorter window can be appropriate for describing current direction, but it should not be generalized to the historical trajectory. For future revisions of the ROI paper, the 1994–95 to 2024–25 completion series can provide a longer baseline, while enrollment data can supply a more leading indicator of whether current pipeline volume is expanding or contracting.

4.3 Chiropractic Institutional Change Is Not Monolithic

The institution-level analysis adds a second layer to the national trend. Every longstanding chiropractic institution with comparable endpoint data became more female and more non-White, suggesting broad change across the educational system. However, institutions followed different racial/ethnic pathways. Some experienced especially large Hispanic growth; others showed stronger Black or Asian/Pacific Islander growth. This heterogeneity argues against describing chiropractic’s demographic transition as a single uniform process.

Institution-level findings also illustrate why federal reporting-unit lineage matters. Stable UNITIDs permit longitudinal analysis through institutional name changes, but the Palmer West reporting discontinuity shows that UNITID disappearance cannot automatically be interpreted as campus closure. Future institution-level work should continue to distinguish educational-market events from changes in IPEDS reporting structure.

4.4 Relationship to the Practicing Workforce

This study complements, rather than duplicates, A Workforce in Transition. IPEDS completions describe awards leaving educational institutions; CMS-based workforce data describe clinicians who later appear in active healthcare practice. The two populations differ in time, eligibility, measurement, and race/ethnicity methodology. The educational pipeline can therefore move more rapidly than the stock of practicing clinicians without creating a contradiction.

For chiropractic, the recent education pipeline is more female and less White than the overall practicing workforce described in the earlier paper. That directional consistency is compatible with continued workforce transition, but no direct conversion rate can be inferred from these analyses. Linking education, licensure, practice entry, retention, and geography would require additional longitudinal data.

4.5 Questions for Future Research

The descriptive findings raise questions that are outside the present study: whether differences in program economics, tuition, debt, admissions selectivity, geographic catchment areas, institutional recruitment, or labor-market expectations are associated with changes in who enters specific professions. Those hypotheses should be tested with independent economic and admissions data rather than inferred from demographic patterns alone.

5. Key Limitations

• Completions are awards, not workforce entrants. IPEDS does not establish whether a completer becomes licensed, enters clinical practice, remains in the profession, or practices in the United States.

• Practice-oriented proxies are not equally clean across programs. Chiropractic, optometry, dentistry, medicine, osteopathic medicine, podiatric medicine, and veterinary medicine have relatively clear professional-practice series; PT, OT, PA, and pharmacy require broader historical award-level rules.

• CIP and award taxonomies changed. Explicit crosswalks reduce discontinuity but cannot guarantee that every historical program and award is conceptually identical across three decades.

• Race/ethnicity reporting changed materially. The long-run White/non-White measure is intentionally conservative and is not equivalent to applying the modern seven-category system retrospectively.

• Unknown race/ethnicity and nonresident counts are excluded from the known-domestic denominator. Institution-level unknown reporting varies substantially and can affect apparent composition.

• IPEDS reports men and women across the historical series. The analysis does not measure gender identities outside that binary structure.

• UNITID is a reporting identifier, not necessarily a permanent campus identity. Mergers, reporting consolidations, closures, and name changes require historical directory review; Palmer West is a material example.

• Five-year pooling improves stability but can conceal shorter-period shocks and year-to-year variation.

• The 2024–25 Completions file is provisional and may be revised by NCES.

• The analysis is descriptive. It does not establish causal relationships among demographics, admissions, financing, educational economics, professional earnings, or student choice.
