Abstract:

Employment estimates combine microdata from the BLS Quarterly Census of Employment and Wages (QCEW) with IRS information on the universe of nonprofit organizations and Form 990 filed by 501(c)(3) charities, refining Salamon and Sokolowski (2005). Systematic errors in EINs correlate with number of employees and jurisdiction. Model-based weights for QCEW establishments matched to IRS records reduce undercount of employment. Undercount varies by NAICS three-digit. Matching also reveals nonreporting of employment on Form 990. Substitution of QCEW employment again reduces bias. State differences in employer obligation to participate in the Unemployment Compensation System exclude employment in many small organizations. The differences cause significant variation in extent of matching, implying additional nonprofit employment. Matched data reduce bias in employment estimates.
