<P> The lower middle class is the second most populous according to both Gilbert's as well as Thompson & Hickey's models, constituting roughly one third of the population, the same percentage as the working class . However, according to James M. Henslin, who also divides the middle class into two sub-groups, the lower middle class is the most populous, constituting 34% of the population . In all three class models the lower middle class is said to consist of "semi-professionals" and lower level white collar employees . An adaptation by sociologists Brian K. William, Stacy C. Sawyer, and Carl M. Wahlstrom of Dennis Gilbert's class model gave the following description of the lower middle class: </P> <P> The lower middle class...these are people in technical and lower - level management positions who work for those in the upper middle class as lower managers, craftspeople, and the like . They enjoy a reasonably comfortable standard of living, although it is constantly threatened by taxes and inflation . Generally, they have a Bachelor's and sometimes Master's college degree . </P> <P> Taking into account the percentages provided in the six - class model by Gilbert, as well as the model of Thompson and Hickey, one can apply U.S. Census Bureau statistics regarding income . According to these class models the lower middle class is located roughly between the 52nd and 84th percentile of society . In terms of personal income distribution in 2005, that would mean gross annual personal incomes from about $32,500 to $60,000 . </P> <P> As 42% of all households, and the majority of those in the top 40%, had two income earners, household income figures would be significantly higher, ranging from roughly $50,000 to $100,000 in 2005 . In terms of educational attainment, 27% of persons had a Bachelor's degree or higher . </P>
