Improving Measurements for Loneliness and Isolation Act of 2025

This bill tells the Department of Health and Human Services to set up a national working group to create clear, standard ways to measure loneliness and social isolation, and to define these terms in plain language for the public . The goal is to make research and health care more consistent and useful, and to help people better understand these issues. The group must share its recommendations with Congress and post them online within one year, and it will end after 2027 .

The bill also spells out simple definitions: “loneliness” is the feeling of being isolated, while “isolation” means actually having few or no social connections.

• Who is affected: Researchers, health care providers, federal health agencies, selected state representatives, and the general public who will see clearer information and tools.
• What changes: Standard measurement tools and definitions across studies and health care; a review to line up older methods; at least three group meetings; a public report within a year .
• When: Work begins after the bill becomes law; the report is due within one year; the group sunsets on December 31, 2027 .
