"In the [2010 National Association of Child Care Resource & Referral Agencies] study, Massachusetts, with an average cost of $16,500 per year for full-time care, was the most expensive [state for child care costs] overall and least affordable for single-mother families and two-parent families with infants, the NACCRRA study shows. Using the median income for a single mother in Massachusetts ($28,510), that's 58.7 percent of her income for child care.
In Louisiana, the average single mother income is $18,435, the study shows. The average $5,900 a year cost for child care eats up 32 percent of a single mom's annual income."
