Taylor Nagle

Program Coordinator at I2D2
Iowa State University


In 2015, Heather Rouse and Cassandra Dorius came together to leverage their combined three decades of experience in education, human services, public health, and integrated data systems to establish I2D2 as the state of Iowa’s first integrated data system for decision-making.

I2D2 brings together administrative data from across health, education, and social service programs; generates anonymized files for analysis to explore patterns and identify strengths and needs; and uses analytic findings in cross-agency discussions about Iowa’s pressing problems. Reports from the U.S. Commission of Evidence-Based Policymaking have increased attention on the potential of integrated data systems to address gaps in service coordination, population-level surveillance, and service responses. With actionable intelligence derived from I2D2, state and program leaders can make powerful, targeted decisions to improve the lives of all Iowans – with a special emphasis on children and families.
