As nonprofit leaders, we have a responsibility to show the country what’s working and what’s at stake on the frontlines of America’s most vulnerable communities. But social-sector hard data is sparse at best, and real-time data is even rarer. The longer our sector remains an outlier in a data-driven world, the greater the opportunity cost—and the greater the risk that others will inappropriately use what numbers there are to justify budget cuts and other misguided decisions.
