What share of total income in Germany is owned by the country's top income earners and how has this share developed over the past decade? Answers to these questions can be found both in representative survey data such as the longitudinal Socio-Economic Panel (SOEP) study and in administrative data on income taxation. After the statistics have been harmonized accordingly, it becomes clear there remain systematic differences for the top one percent's incomes - both in terms of the level of measured income concentration and in terms of changes over time. However, the two sets of data are very similar for the top ten percent excluding the top one percent as far as both level and trend of income shares are concerned.
