The study's authors make a few references to age: "While wealth is getting older on aggregate, in the top 0.1% of the distribution wealth is getting younger: the share of top 0.1% wealth held by elderly households is lower in 2012 (39%) than in 1962 (46%). In 1962, top wealth was significantly older than average, while today it is about as old as average. This finding is consistent with the results of Edlund and Kopczuk (2009) showing that there were relatively more widowed women in top wealth groups in the 1960s than in the 1990s."
