True cost of becoming a mum highlighted in new data on pay
Mothers in England lose an average of £65,618 in earnings five years after their first child due to reduced work hours and career progression barriers, Office for National Statistics data shows.
- New research by the Office for National Statistics found having children leads to a substantial and long-lasting earnings reduction for mothers, with 249,480 women in England earning 42% less five years after a first child.
- ONS analysts said earnings cuts reflect structural shifts such as moves to part-time work, with paid work probability dropping 15 percentage points at 18 months after a first child.
- Across five years the data reveal mothers lost an average of £65,618 after a first child, £26,317 after a second, and £32,456 after a third, totaling over £124,000 for a mother of three.
- Campaigners warned up to 74,000 new or expectant mums lose jobs annually due to discrimination, urging urgent reform of parental leave and childcare policies.
- The findings feed into concerns about pensions as the motherhood effect drives a 48% gender pensions gap, while new laws last year strengthened redundancy protections and 94% of nurseries expect fee rises this year.
