T HE I NTERNATIONAL I NCOME D ISTRIBUTION D ATA S ET (I2D2) June 2013

The I2D2 is a global harmonized household survey database. A basic set of harmonized variables that are comparable across country/time. 1 Stata data file per survey, at the individual member level. The I2D2 started with 2006 WDR on Equity. It has since grown, and been used in subsequent WDRs and other flagships. Not intended to replace original data sets for research focused on national (or even regional, in some cases) cases. What?

The I2D2 database includes 5 “categories” of variables: HH level: basic attributes, consumption/income aggregate.  Consumption/income aggregates are taken as provided. Individual level (HH members): demographics, education, labor force (subject to age coverage of the survey).  The labor force variables were expanded for the WDR2013 on Jobs. The I2D2 database currently includes 600 surveys for 120 countries. Content and Coverage

We get raw/original and, when available, standardized files from the regional survey data teams. In some cases, we go to country economists or NSO websites/teams to get the data.  The I2D2 is not a WB facility for storing unit-record Household Survey data from NSOs (despite collecting such data for harmonization). How?

Currently, available in the WB. Soon to be posted on the DECDG micro data library. But what about people outside the WB and those in the WB who don’t have/know Stata? 2 possible avenues: 1.Tableau dashboard for basic statistics 2. ODAT (see CLSP under for regression analysis Access

Pincer strategy: advance on several fronts simultaneously: Identify, collect, and add surveys Clean the database Get in the micro data library (thanks Olivier!) Get online (that is going slowly) Secure funding! Forward
