Just over half of parents in families with a mom and a dad both worked full time last year, setting a record high, according to a new Pew Research Center analysis out Tuesday.

The big picture: It comes as college-educated women are flocking to the workforce — and as cost-of-living concerns strain families.

---

By the numbers: Fifty-two percent of different-sex couples with minor children are made up of two parents who work full time, up six percentage points from a decade ago and 21 points since 1975, according to Pew’s analysis of U.S. Census data.

• The share of families where the dad works full time and the mom is not employed fell from 42% in 1975 to just 23% last year.
• The analysis focused on different-sex couples because there weren’t enough same-sex couples in the sample.

Between the lines: Family work arrangements differ based on factors like race and ethnicity.

• The share of white and Asian mothers in families with two full-time working parents have increased throughout the 2000s, to 54% and 52%, respectively.
• Most Black mothers work full-time along with their male partners (60%), but this was already the case back in 2000, when 64% of Black moms also had full-time gigs.
• Meanwhile, the family work dynamic for Hispanic moms has stayed relatively stable since 2000, with 32% not working while their partner works full time.

Degrees also impact family work dynamics: Nearly 7 in 10 moms (69%) with a postgraduate degree married to or living with their partner are found in families with two full-time working parents.

• That’s up from 59% in 2000. A smaller majority of moms with bachelor’s degrees (56%) are in families with this work arrangement, up from half at the start of the century.
• However, the same is true for less than half (43%) of moms with some college experience or less.

Worth noting: Couples’ sentiments about their finances and children vary by their work arrangements, per Pew research from March.

• More than 80% of working parents in dual-income, full-time families say their arrangement is a financial boost, far more than those in families with just a working dad.
• But families with where the mom isn’t employed overwhelmingly say that dynamic is good for their kids’ wellbeing.

The bottom line: The modern family norm is two full-time gigs, two W-2s and a lot of teamwork.
