Big Brothers Big Sisters Lone Star
Overview
Big Brothers Big Sisters Lone Star matches children facing adversity with screened volunteer mentors who meet them regularly, in community-based, school-based and Amachi (children of incarcerated parents) programs. It is a Texas agency based in Dallas whose core markets include Greater Houston, where the program has run since the 1950s; it served 5,110 children in 2024. This in-depth review prices the organization’s whole cost per match against long-run earnings from a tax-record follow-up of Big Brothers Big Sisters’ randomized trial, in which Houston was one of eight sites.
Cost-effectiveness
We estimate $60K per DALY.[1] Nonprofit yearly budget is $13.3M.[2]
Why investigate
The 1991–93 randomized trial of about 1,100 youth found behavior improvements while matched; linked tax records show treatment youth were significantly more likely to attend college.
Main reservation
Our working estimate is about $61K per DALY; all of it is income, and the randomized trial’s own earnings estimate is imprecise.
