 This study found that modern contraceptive usage and unintended pregnancy rates vary significantly across different regions of the world. In particular, the rate of unintended pregnancy was highest in South Asia, followed by Southeast Asia, West Central Africa, and Eastern Southern Africa. The study also found that socioeconomic factors such as educational attainment, employment status, media exposure, and decision-making autonomy were all associated with unintended pregnancy rates. Additionally, the study found that poverty was associated with unintended pregnancy in South Asia and East Africa, but not in Southeast Asia or West Central Africa. These results suggest that there may be regional differences in the effectiveness of modern contraceptive methods, and that socioeconomic factors play a role in determining whether or not individuals use modern contraceptives.
