Steven Ruggles (Director. Institute for Social Research and Data Innovation, University of Minnesota, USA).- IPUMS and the Big Data Revolution.
IPUMS and the Big Data Revolution.- A data revolution is transforming scientific research. Just a few decades ago, investigators had to make do with snippets of information; now we are awash in data. Growth in the quantity and quality of data has opened new research opportunities and stimulated the development of new methods, resulting in a startling acceleration of the pace of discovery. The rapid expansion of data resources created new challenges. Data infrastructure did not keep pace with the explosion in the quantity of data Much data collected at great public expense was inaccessible to most researchers. Constantly changing standards and measures complicated comparisons over time and space. Metadata, where available, was often nonstandard, incomplete, and inadequate for automated processing. With insufficient attention to preservation, valuable data disappeared. IPUMS was established three decades ago to address these challenges. This paper outlines IPUMS strategies over that period to develop and recover large-scale demographic datasets, democratize access, improve interoperability, and ensure long-run preservation.
