Institute for Fiscal Studies report: Wage Progression and the Gender Wage Gap – the Causal Impact of Hours of Work

The hourly wages of female employees are currently about 20% lower than men’s on average, having been 23% lower in 2003 and 28% lower in 1993.

This is from the February 2018 report (pdf) from the Institute for Fiscal Studies on the gender wage gap.

The report finds:

  • The gender wage gap widens gradually but significantly from the late 20s and early 30s
  • Gender differences in rates of part-time and full-time paid work account for approximately half of the widening of the gender wage gap over the 20 years after the first child in a family is born
  • There is, on average, a wage gap of around 10% even shortly before the arrival of the first child.
