(NEWSER) – The US birthrate last year was the lowest since records began in 1920, dropping to 63.2 per 1,000 women, Pew data shows. Between 2007 and 2010, the rate fell 8% among all women aged 15 to 44. It fell 14% among foreign-born women, compared to 6% among women born in the US. And among Mexican immigrant women, it dropped 23%. The recession appears to have played a major role: Foreign-born women were deeply affected by the downturn, and Hispanic women born in the US and abroad have seen household wealth drop more than any other group since 2007.
