Child poverty jumps one month after tax credit expires, study says. The number of children living in poverty in the United States increased by 41% just one month after the expanded child tax credit payments stopped. According to the Center on Poverty and Social Policy at Columbia University, when the monthly payments of $250 to $300 per child ended in December 2021, the child poverty rate rose from 12% to 17% by the end of January 2022, representing an additional 3.7 million children living in poverty. Black and Latino children saw the biggest jump in poverty rates. The Biden administration intended to make the tax credit permanent, but it ended with the failure of the Build Back Better Act.
