PROJECT OVERVIEW | COORDINATION | HARMONIZATION | DISSEMINATION
IECM forms part of IPUMS international, a global collaboratory of
National Statistical Offices and Universities to:
1. Inventory the world’s census microdata
2. Preserve endangered microdata and documentation 3. Integrate census microdata
a. use standards of UNSD, EuroSTAT, ISCO, ISCED, etc.
b. facilitate comparative research in time and space
4. Anonymize census microdata to preserve statistical confidentiality, using highest standards
5. Disseminate restricted access, custom extracts to approved researchers at no cost

6. Browsing IECM data on the web: new tools for data analysis
PROJECT OVERVIEW | COORDINATION | HARMONIZATION | DISSEMINATION
Browsing IECM data on the web: new tools for data analysis
How are we currently disseminating the IECM census microdata?
- Through a state of the art extraction system where users can create custom tailored microdata samples
Why a data browser?
Fast and convenient tool to explore the contents of the database before making an extract
Secure form to access microdata
It opens census data to a wider audience
It prevents users to download microdata (if only basic figures are needed)
Some caveats
We are not providing official statistics
Frequencies are not based on 100% population counts. Sampling erros must be calculated
Compared to microdata, cross-tabulated data have less analyitical power
