Upward mobility

In 1999, about 33% of households earned $52,000 (today’s equivalent of $100,000 when inflation adjusted). As of 2023, about 41% of US households earned $100,000 or more. So in a quarter century, we have seen roughly an 8 percentage point increase in upward mobility for these income earners. Almost all income groups have seen upward mobility. Searching online (US Census, Statista…) provides more such nuggets of information.
