> In 2008, women reported that more than half of all pregnancies (51%) were unintended. By 2011, the percentage of unintended pregnancies declined to 45%. That is an improvement, but some groups still tend to have higher rates of unintended pregnancy. For example, 75% of pregnancies were unintended among teens aged 15 to 19 years.
I imagine this has continued to trend downwards since 2011, especially amongst women who had the option of remote work (more educated, more lucrative careers, higher degree of financial freedom, less religious, etc).
