Presentation by Dr. Miriam King.
IDHS is a new NICHD-funded data integration project that lowers the barriers to cross-temporal and cross-country research using the Demographic and Health Surveys, focusing initially on Africa and India. IDHS recodes data consistently across samples without losing detail, displays variable availability at a glance, offers variable-specific documentation (including question universes and wording and discussion of comparability issues), and merges files on the fly to create customized data extracts. This presentation will summarize MPC’s approach to integrating microdata, with examples from IDHS, describe the value-added features of IDHS, and summarize future plans for IDHS. At the time of the presentation, IDHS will include data on women of childbearing age, their households, and children under 5, from 18 countries and 77 samples.
