Complementary means of disseminationServe different constituencies
Census Hub
open access, counts, descriptive statistics
IPUMS Microdata
research or policy access, multivariate analysis
Census Hub and IPUMS Microdata
Census Hub
Census Hub: Summary Data
Census Hub: Cross-National
Relation to head
Marital status Education Occupation
Microdata
Microdata vs. Hub Data
Both: harmonize data internationally; pooled output; provide metadata
Microdata samples = flexibility (IPUMS/IECM)
•Download data for analysis
•Multivariate modelling
•Denominator
•Household-level samples: individual behavior in context
Household Microdata Example:Foreign-born persons in union with native-born (ca. 2000)
Coherence Hub and IPUMS/IECM sample data Between sources Across census years
Method: cohort analysis By birth year Proportion completed secondary education
Expected Results: Results should match for each year of birth
Between sources from the Hub and IPUMS/IECM Across censuses from different years Net of some effect of migration and mortality
Statistical CoherenceComparison of Hub and IPUMS Data

High degree of correspondence with official totals
Census microdata dissemination benefits• High quality documentation• Persistent data quality assessment• Large research and policy impact• Excellent user support
Results and ReflectionsIPUMS/IECM census microdata
Researchers and the IPUMS goals
•Preservation NSO: Current and future Res: Change over time – empirically •Harmonization NSO: Standards in National Context Res: Cross-country and cross-temporal
•Dissemination NSO: Specific format Res: Single format across all data sources
•Serves small specialty audience
