Birth Control Pill Statistics

GITNUXREPORT 2026

Birth Control Pill Statistics

Nearly half of pregnancies in the United States are unintended, and contraceptive nonuse or incorrect use accounts for 44% of unintended pregnancies from 2015 to 2019. This page connects that gap to real pill experience and safety data, including a 7% typical-use pregnancy rate and a 0.3% per year VTE incidence, while also tracking why telehealth starts jumped from 3% to 22% between 2019 and 2022 and how oral contraceptives still carry benefits like about a 10% colorectal cancer risk reduction.

Even with modern contraceptive options, the gap between use and real world outcomes is still striking, with 44% of unintended pregnancies in the United States linked to contraceptive nonuse or incorrect use from 2015 to 2019. At the same time, pill use can meaningfully shape health risks and cycle patterns, from about 10% lower colorectal cancer risk to predictable withdrawal bleeding for many users within three months. The statistics vary sharply by country and measure, and that tension helps explain why the “same pill” can look very different depending on who is using it and how.
