Poor women find it hardest to afford birth control, says columnist Froma Harrop, and so are most likely to go without it, leading to higher rates of unplanned pregnancies and abortion. Harrop argues that not requiring employers to provide contraception without co-pay limits the options of those who need it most, and pennlive.com’s Rebecca Rutenberg describes the shock of discovering a month of birth control pills costs $49.99.  Mother Jones goes a step further and calculates the lifetime cost of a variety of birth control methods.—Ryan Scott
