With more than 6,300 charitable organizations, Austin has Texas’s most crowded nonprofit field, a situation that could be creating inefficiency and duplication of effort, The Austin American-Statesman reports.

A study by Greenlights for Nonprofit Success found that the Austin area had 3.82 charitable nonprofit groups per 1,000 residents, more than any other large Texas city and tied with Oklahoma City for most in the Southwest.

Greenlights’ executive director, Matt Kouri, said there is “overpopulation” in some areas of the charitable field, and many local organizations “could benefit by merging, collaborating, or sharing services.”
