The Decennial Transformation and Application Modernization (DTAM) project is a strategic initiative to transform the U.S. Census Bureau's Decennial Census Programs into a modern, data-centric, cloud-smart IT environment supporting the 2030 Census and the American Community Survey (ACS). This effort focuses on modernizing and integrating applications and data systems, reducing technical debt and lifecycle costs, and enabling secure, scalable, near–real-time data processing and analytics to improve the speed, quality, security, and efficiency of census operations.
