The Massachusetts Senate Committee on the Census held a significant meeting on September 22, 2025, highlighting the critical role of the Massachusetts Address Database (MAD) in supporting the upcoming 2030 Census. The MAD, a vital resource for various state agencies, has proven invaluable in enhancing the accuracy of census data, which directly impacts representation and resource allocation for residents.

During the meeting, officials emphasized the successful collaboration between the Massachusetts Joint Information Services (Mass JIS), the UMass Donahue Institute, and the Census Bureau. This partnership has led to a remarkable increase in the accuracy of census counts, with the 2020 Census recording 136,000 more residents than initially estimated. This achievement not only bolstered Massachusetts' population figures but also alleviated concerns about potentially losing a congressional seat.

The MAD serves as a foundational tool for numerous state initiatives, including the validation of voter addresses and the mapping of essential services. The data from MAD has been instrumental in various projects, such as the Massachusetts GIS initiative, which aids in associating census geography with voter precincts. This ensures that electoral boundaries reflect the most accurate population data, fostering fair representation.

As the state prepares for the 2030 Census, the importance of maintaining and improving the MAD cannot be overstated. With a dedicated team of 12 full-time staff, Mass JIS is committed to sustaining this resource, which supports a wide range of services from health and human services to public safety and housing initiatives. The ongoing efforts to enhance the MAD will ensure that Massachusetts is well-prepared for the next census, ultimately benefiting all residents through improved data accuracy and resource distribution.

In conclusion, the discussions at the Senate Committee meeting underscore the vital connection between accurate census data and community well-being, reinforcing the state's commitment to effective governance and representation for its residents.
