<p>your hypothesis is incorrect: the Mean Number of Earners per Household is increasing in income for each Quintile. </p>

<p>I am surprised by the average number of earners in the highest quintile, but I think it is not very surprising that the poorest people are poor because they have trouble finding stable employment. </p>

<p>I have a hypothesis that single-income families greatly increase as you get into the mid to upper middle class bracket. And that 2+ income sources are common in lower classes and also the extremely rich.</p>

<p>I can't verify this though because I can't find any research that looks into how many single income households there are by class. Instead, I see mostly gender connections. </p>

<p>Does anyone know of any research that could be helpful here?</p>
