Official figures show that there are now 300,000 fewer mothers at home that previously estimated.
Experts said that those who decide to sacrifice their career in order to look after their children at home are now considered in the minority.
According to returns in the 2011 census, there are almost 1.6 million women who do not work because they are looking after their home and family.
This is about 298,000 fewer than estimates previously, the Office for National Statistics said.
