6NSI entrusts census metadata and anonymized
microdata to MPC
MPC integrates metadata and confidentializes
microdata samples
.
IPUMS-International manages access and entrusts
researchers with custom-tailored ltddigt , SAS,
STATA, and SPSS metadata and microdata extracts
for any combination of countries, censuses,
sub-populations, and variables
.
IPUMS-International microdata extract
system Trusted researcher downloads customized
extracts
7How IPUMS-International adds value to census
microdata
- Conditions of access to census microdata are the
same for all countries and users (registration
required, free of cost). - Statistical confidentiality and security
disclosure controls, access restricted to
researchers - Integration/harmonization census microdata and
metadata - E.g. migration since birth, last 1/5/10 years,
previous residence - Dissemination custom tailored extracts
country(ies), census(es), sub-populations,
variables, sample density, metadata all are
customizable by the researcher - Sharing -
- Microdata with national statistical office
partners - Research results with other researchers, NSOs,
etc.
