Big data, that is, data that are byproducts of our lives
rather than designed for research purposes, are the
newest of the information highway innovations. One of
the important challenges to social and behavioral sci-
ence data collection, curation, and dissemination for
the foreseeable future is to link diverse forms of data in
a way that is cumulative, representative, meaningful,
and accessible to a broad range of researchers. It is
critical to explore the new questions these data can
address and to develop new methods to address them,
including linking persons and information about them
and their environments across different data platforms
while maintaining confidentiality and privacy. Linking a
broad array of information-from administrative data
(local and state and regional), to social media (Twitter,
Facebook), to census and other surveys, to ethno-
graphic data, and data from experiments such as rand-
omized controlled trials-to address how humans and
their communities make decisions is challenging. This
issue was addressed by papers presented at a confer-
ence on New Data Linkages convened by the Social
Observatories Coordinating Network in 2016; those
articles are brought together in this volume.
