What underlying factor is most likely contributing to the high rates of poverty among single mothers in America?

One major factor contributing to the high rates of poverty among single mothers in America is the lack of sufficient income. Many single mothers work jobs that pay low wages or have unstable hours, making it hard to cover basic needs like housing, food, and childcare. For example, a single mother working part-time at a minimum wage job may struggle to afford daycare for her children, which limits her ability to work more hours or pursue better-paying opportunities. Additionally, single mothers often face high costs for childcare and may lack access to affordable housing, which can push them deeper into poverty. Overall, the combination of low income and high expenses creates a challenging situation for many single mothers.
