WASHINGTON — US President Barack Obama urged Americans Saturday to keep fighting for women's equality, despite progress made in this area over recent decades.

"Women are still more likely to live in poverty in this country," the president said in his weekly radio address.

He said that there were areas like mathematics and engineering where women were vastly outnumbered by their male counterparts.

"This is especially troubling, for we know that to compete with nations around the world, these are the fields in which we need to harness the talents of all our people," Obama said. "That?s how we?ll win the future."

The president's comments were timed to Women?s History Month that is celebrated in the United States in March.

Obama reminded that one of my first acts as president was to sign a law allowing women who believe that they have been discriminated against in their salaries to have their day in court.

He also said he was disappointed that a bill aimed at giving women more power to stop pay disparities -- the Paycheck Fairness Act -- had been blocked by just two votes in the Senate and promised to keep up the fight to enact reforms that were contained in that bill.

"Achieving equality and opportunity for women isn't just important to me as president," Obama said. "It's something I care about deeply as the father of two daughters who wants to see his girls grow up in a world where there are no limits to what they can achieve."
