Well-informed decisions increasingly depend on multiple data sources.

NORC has the deep and wide-ranging skill set necessary to integrate data from different sources, creating new data products that can be more useful than the sum of their parts. We integrate data through record linkage and data fusion, including statistical matching, and develop improved methods for supplementing our probability samples with records from other sources. We use small area modeling to improve estimation within small geographic areas or demographic domains by using additional data sources in conjunction with probability samples.
