Fully 42 percent of American mothers were the sole or primary income earners in their families in 2015, the Center for American Progress reports, an all-time high.
By state, the share ranges from a low of 26.3 percent in Utah to a high of 53.5 percent in Mississippi. Florida ranks fifth-highest with a share of 46.8 percent.
The share of women as primary breadwinners has steadily increased over the past four decades, reflecting an increase in single-parent families and the decline of male-dominated jobs in manufacturing and construction.
