National Center for Charitable Statistics Data Archive
The data produced by NCCS are intended for use by researchers and policy-makers in their
quantitative analyses, and as a springboard for more in-depth survey or case study research.
While NCCS employs a range of data checking procedures, our limited resources do not permit
systematic in-depth verification of every record. If your focus is on individual organizations or on categories where a few large organizations account for the majority of financial activity or resources, we strongly advise that you include inspecting financial data for dominant individual organizations as part of your analysis plan.
