As health departments modernize their data systems, an unexpected challenge has emerged: traditional public health job classifications no longer match the reality of today’s data landscape. In this episode, Ari Whiteman, ASTHO’s Senior Advisor for Public Health Data and Informatics Workforce, talks about why the field urgently needs new informatics-focused roles, and what it will take to build them. Whiteman explains how interoperability, electronic health records, and complex data pipelines have outpaced legacy classifications like epidemiologist or public health analyst. Leveraging the Public Health Infrastructure Grant (PHIG), state, local, and territorial health agencies can build classification systems that enhance recruitment and retention of an informatics-savvy workforce. Updating job classifications can help clarify new roles, alleviate pressure on existing roles, and enable health agencies to sustain workforce infrastructure that is flexible and forward-looking. He discusses the hesitancy and bureaucracy that make change difficult, the opportunity cost of doing nothing, and why modernizing job classifications is essential for faster outbreak response, stronger surveillance, and smarter public health decision-making.Data Modernization Primer and Tactical Guides | ASTHOHow to Modernize Data Infrastructure: A Toolkit for Public Health Leaders | ASTHOASTHO Announces Sixth Developing Executive Leaders in Public Health Cohort | ASTHO
