The average net worth of the lower half of the distribution, representing 62 million households, was $11,000 in 2013. About one-fourth of these families reported zero wealth or negative net worth, and a significant fraction of those said they were ‘‘underwater’ on their home mortgages, owing more than the value of the home. This $11,000 average is 50% lower than the average wealth of the lower half of families in 1989, adjusted for inflation.
