Mums in the US are increasingly being branded “mums” by women’s rights campaigners, a sign of the country’s growing acceptance of the “motherhood” concept.

In an annual survey, the National Center for Women and Information Technology found that the average US mother in 2014 was earning more than $100,000 per year.

That figure was nearly double the median American mother’s salary in 2014, according to the Center for American Progress, a liberal think tank.

The report said that the vast majority of mothers in the United States are employed full-time, have children, and have a home and car.

It said that in the 1970s, more than 70% of US mothers worked full- or part-time.

The Center for the Study of Women and Gender, a conservative think tank, said the rise in “mother-friendly” businesses like massage parlours and private homes for women was a “welcome shift” that has allowed women to earn more money and live better lives.

“Women now enjoy the same economic opportunities as their male counterparts,” said Michelle Krebs, a senior researcher at the Center.

But the rise of “mothers” in the country has not gone unnoticed in the rest of the world.

The United Nations Population Fund reported last year that the number of “moms” in countries like the UK and US was on the rise, with more than 3.4 million mothers now in employment.

The UK’s National Institute for Health and Care Excellence (Nice) said the number was expected to climb to 3.6 million by 2020.

Moms in the Philippines are also becoming more common, with a growing number of Filipinas reporting they are working more hours to support their families.
