Key changes in the new definition include: i) the inclusion of the value of goods produced by households for their own consumption, as an element of self-employed income, and ii) the deduction of current transfers paid by households to non-profit institutions and other households (e.g. alimonies). The new income definition implies a break in OECD historical series that makes it impossible to use for analyzing long term trends. For this reason, we used data available for at least one common year (typically either 2011 or 2012) based on both definitions to correct the most recent data so that they match the data series obtained with the old definition.
