PHILADELPHIA (CBS) — Mother’s Day is rapidly approaching so it’s important to recognize that women make up nearly half of the U.S. workforce.

With that fact in mind, it is essential to consider which states are the best, or worst, for working moms. A new study finds that New Jersey and Delaware crack the top ten of the best states for working moms.

More than 70 percent of working women are moms with young children.

Studies find that women only earn 82 percent of what men made in 2017. In the workplace, women generally experience far less upward mobility than their male counterparts.

These gaps of inequality tend to spark debates about gender roles in the community.

According to Wallethub, these problems can lead to a strain on employment places and their employees when considerations for parental leave policies and other legal support systems are different from state-to-state.

It also begs the question whether women should be forced to choose between career and family.

To help answer this question, WalletHub compared state dynamics across 15 key metrics to identify the best and worst states for working moms.
