The number of working hours of Dutch mothers rose 50 percent over the past decade to an average of 16.4 hours a week, Dutch paper De Volkskrant reported, quoting Dutch central statistics office CBS.
Meanwhile, the percentage of mothers who do not work fell to 28 percent from 50 percent 10 years ago, the paper said.
For those mothers who work, they spend nearly 23 hours a week on the job, compared to the average 26 hours for all Dutch workingwomen.
The Dutch government has made getting more mothers to work one of its central strategies to boost employment rates. Since 2007, all Dutch primary schools have to provide after-school supervision.
Demand for formal childcare has led to an overspend of one billion euros in the education ministry budget, the paper said. Parents pay on average 19 percent of the cost themselves, compared with 37 percent in 2005.
