There is a large demand for household distributional information in line with national accounts totals, as it provides comprehensive, coherent and comparable results that are consistent with macroeconomic aggregates. For that reason, the OECD has launched two expert groups to develop distributional estimates. Both are mandated by the G20 Data Gaps Initiative to address the demand for distributional information for the household sector in the G20 and beyond.
On income, consumption and saving, the OECD together with Eurostat launched an expert group in 2011 to develop distributional results on income, consumption and saving in line with national accounts aggregates, i.e. the Expert Group on Disparities in a National Accounts framework (EG DNA). This expert group developed a methodology to compile distributional results in line with national accounts on the basis of available micro data sources, and engaged in a couple of exercises to compile experimental results. The most recent exercise was conducted in 2025 and these results have been made available in the public databases of the OECD and Eurostat as experimental statistics. In the meantime, several countries have also started to update these results on a regular basis. In view of the G20 Data Gaps Initiative , a new collection round will be conducted in 2026.
On wealth, the OECD launched the Expert Group on Distributional Household Wealth (EG DHW) in 2023. This group shares the same methodological framework as the EG DNA, and has started foundational work on mapping microdata to the National Accounts household balance sheets. Research and discussions are ongoing to finetune the methodology, improve micro-macro linkages and provide estimations for complex wealth items. The EG DHW recently conducted its first data collection round in 2025 to compile experimental results in view of the G20 Data Gaps Initiative. Some key results can be found in this working paper. A next data collection round is foreseen for 2026.
