We assume a similar definition would apply, making the agricultural season March 2008 to April 2009.

Datasets Tabulated from IPUMS International Microdata

IPUMS International microdata consist of individual- and household-level records for a sample of the enumerated population. In other words, each record consists of one person's responses to all the questions in the census. IPUMS International disseminates a sample of such records, typically between 1 and 10%, for each census. Microdata samples can be tabulated to generate aggregate data tables by counting the number of records with certain characteristics and accouting for weighting within the sample. Because the data are derived from samples, rather than the complete enumeration, the values may differ from published tables.

We defined a standard set of tables to tabulate from IPUMS International samples, provided the variables required for the tabulation were present in the sample. For example, we would be unable to tabulate the percentage of households with internet access for a particular census if it did not ask about internet access.

Aggregate data tables tabulated from IPUMS International microdata were originally created for IPUMS Terra and are preserved in IHGIS as part of the legacy of the Terra project.

The data imported from IPUMS Terra correspond to IPUMS International data as they were in September 2018, prior to the expiration of IPUMS Terra funding. As such, they do not include all samples currently available in IPUMS International. Data may also differ slightly from current IPUMS International data due to more recent corrections and improvements in IPUMS International.
