Our Work

CWORPH is the home of the nation's first HRSA/CDC Public Health Workforce Research Center and the site of numerous other innovative research projects related to public health workforce.

Our research

HRSA/CDC Public Health Workforce Research Center

The Public Health Health Workforce Research Center (PHWRC) is a joint initiative between the U.S. Centers for Disease Control and Prevention (CDC) and Health Services Research Administration (HRSA).  This cooperative agreement provides funding over 5 years (2022-2027) for research focused on:

  1. Evaluating the role(s) of public health occupations in delivering programs, including essential or foundational public health services, across populations.
  2. Investigating public health workforce composition, data, needs, sufficiency, and distribution including both governmental (i.e., federal, state, local, tribal, territorial) and non-governmental entities.
  3. Assessing public health workforce development methods including but not limited to recruitment and training models and the outlook and analytics for workforce needs.
  4. Conducting and evaluating public health workforce implementation scientific research, including identifying evidence-informed strategies and interventions. CWORPH Principal Investigators collaborate with partners to conduct 8-10 studies per year, with guidance and direction from both CDC and HRSA.

Enumeration of the Public Health Workforce

For decades, public health practitioners, policy-makers, and, at times, the public, have asked how many people work in public health. These numbers are important to set a baseline to inform and evaluate workforce infrastructure-building efforts. Yet, the federal government has never systematically answered this question; enumerations of the governmental public health workforce have long been left to non-profits, academics, and others in the field. The reasons for this are many but ultimately reduce to:

  1. Lack of licensure data for public health officials.
  2. Disagreement over how to define the taxonomies of public health workers. Public health has attempted to resolve these two issues since 1908, when the first “limited enumeration” of the field was undertaken.

 

The latest effort, Enumeration 2024, is a collaboration with the Public Health Accreditation Board (PHAB) that aims to build upon recommendations for addressing data challenges while moving forward the methods for enumerating local, state, and federal governmental health employees. The purpose of this project is to expand on previous enumerations by providing three distinct enumeration efforts: 

  1. Total counts enumeration of the full governmental public health workforce
  2. Occupation-specific enumeration. 
  3. Analyses and enumeration of public health nurses using novel data.

CDC National Partners Cooperative Agreement

CWORPH is funded through the Centers for Disease Control and Prevention (CDC) National Partners Cooperative Agreement, which supports analysis and evaluation related to local governmental public health issues, particularly workforce recruitment and retention. Current projects include a focus on Capacity and Cost Assessments, Community Health Workers, and Burnout.

Enumeration 2024: What We Know and What We Wish We Knew About the Governmental Public Health Workforce in a COVID-19 Recovery Landscape

Workforce estimates show that while state and local public health staffing rebounded to around 239,000 employees in 2022, this growth hasn't kept pace with population increases, and many hires were temporary. Regional disparities, underrepresentation of public health nurses, and looming workforce departures highlight the urgent need for sustained investment, strategic planning, and stronger data collection across all levels of government, including Tribal and territorial agencies.

Enumerating the State and Local Public Health Workforce During the COVID-19 Response

A 2023–2024 enumeration found 239,000 staff employed in state and local health departments, revealing a 2% increase since 2012 but significant workforce losses in several states, especially in the Southeast. The findings highlight chronic underinvestment in public health and call for stronger, sustained federal funding and improved enumeration methods across all government levels.

Enumerating the US Governmental Public Health Workforce

Enumerating the US governmental public health workforce is crucial for strengthening infrastructure, guiding workforce planning, and addressing staffing needs at federal, state, and local levels. Enumeration 2024 builds on this effort by using a multi-pronged approach to assess the size, key occupations, and changes in the public health workforce since 2012.

Issue Brief: Public Health Occupations and the Standard Occupational Code System

The Standard Occupational Classification (SOC) system is the federal standard for categorizing occupation data, used by the Bureau of Labor Statistics (BLS) to collect and analyze workforce information. However, the current SOC and North American Industry Classification System (NAICS) codes lack the granularity needed to accurately enumerate the governmental public health workforce in state, local, Tribal, and territorial health departments.

The Demoraphics, Training, and Job Functions of the United States Public Health Service Commissioned Corps Nursing Workforce

This research examines the demographics, training, and job functions of nurse officers in the U.S. Public Health Service (USPHS) to improve measurement of the public health nursing (PHN) workforce. The findings underscore the value of job function questions in workforce assessments and suggest USPHS nurses could provide insights for strengthening diversity in the nursing profession.

Distribution and Specialties of Broadly Versus Narrowly Defined Public Health Nurses Working in Government Settings in the United States, 2022

Using 2022 data from the National Council of State Boards of Nursing, researchers found that PHNs make up 3.7% of registered nurses (RNs) in government settings under a broad definition and 1.8% under a more restrictive definition. The study highlights that PHNs often identify as generalists and work in diverse settings like public health, school health, and correctional health.
