New data, released last week as part of the National Survey of Family Growth, finds that 6.4 percent of women ages 15-to-44 are currently relying on intrauterine devices (IUDs) as a method of contraception. While this lags behind those who are using the pill (16 percent) and even sterilization (15.5 percent), it shows a renewed interest and increased trust in a highly effective birth control method that had fallen out of favor. This is good news for public health advocates—many of whom believe that long-acting methods like the IUD are the key to preventing unintended pregnancy in this country.
