Governor Lamont Commemorates International Open Data Day and Open Data in Connecticut

(HARTFORD, CT) - Governor Ned Lamont today is marking International Open Data Day - which is celebrated this year on Thursday, March 5, 2026 - by highlighting how Connecticut is supporting transparency and providing public access to state data through the Connecticut Open Data Portal at data.ct.gov and the Geodata Portal at geodata.ct.gov.

The portal was launched to make data collected by the state government more open and easily accessible to its owners, the residents and taxpayers of Connecticut. The state's open data efforts aim to make data easily accessible to individuals, researchers, entrepreneurs, academics, policymakers, and other state agencies to spur innovation and collaboration in the state.

"Connecticut's open data resources, including data.ct.gov and geodata.ct.gov, give residents, researchers, and organizations access to a powerful range of information that supports informed decision making," Governor Lamont said. "These platforms make state data instantly available, customizable, and useful for understanding spending, tracking recovery efforts, supporting workforce and economic planning, improving public health, advancing sustainability, and addressing long standing inequities. The state's commitment to open data has earned national recognition and continues to expand in reach and impact."

Twelve years since its establishment, the Connecticut Open Data Portal continues to make data collected by state agencies accessible to the public to promote government transparency. The portal hosts more than 600 datasets published by state agencies and over 35 data stories that highlight trends in the data hosted on the portal, serving more than 185,000 users in the last year.

The portal provides transparency on critical topics that impact Connecticut and inform policymakers, employers, and residents. In the past year, additions to the portal have included:

• Making data more accessible through the development of new data stories including:
  • Small Business Certification Program
  • Workforce Pathways: Workforce and Education
  • Medical Marijuana Program
  • Environmental Justice Public Participation Plans and Reports
  • Disconnected Youth in Connecticut

• Updated guidelines and resources, such as Geodata Portal Publishing Guidelines to complement the Open Data Handbook.

Open Data Day is an annual celebration of open data - data that can be accessed and used by anyone for any purpose - all over the world. Groups from around the world create local events on the day where they will use open data in their communities. It is an opportunity to show the benefits of open data and encourage the adoption of open data policies in government, business, and civil society.
