The extent to which the State Children's Health Insurance Program (SCHIP) crowds our private insurance is poorly understood.
To assess the incidence of crowd‐out and enrollee characteristics associated with crowd‐out.
Parent telephone survey for 2,644 children after enrollment in NY SCHIP.
Crowd‐out is measured based on enrollee reports of coverage (and loss of coverage) before SCHIP. Multivariate logistic regression is used to relate crowd‐out to enrollee characteristics.
Only 7.1 percent of SCHIP enrollees dropped private coverage ≤6 months before SCHIP, suggesting relatively modest crowd‐out. Crowd‐out was associated with some enrollee traits including income, but not with health status.
Most movement from private to public insurance in NY was not crowd‐out. Under current program structure in NY, crowd‐out concerns should not dampen enthusiasm for SCHIP.
