<p>Map of estimated subnational contraceptive supply shares in Rwanda over time.</p>

The mean estimates of private sector supply shares of the five contraceptive methods across the five provinces of Nigeria. The colour captures the mean supply shares where light blue colours capture supply shares near 0 while the deep red colour captures supply shares approaching 100%. Five years of estimates are given at 10-yearly intervals from 1990 to 2020 and then the present year, 2025. The A label shows the supply of female sterilization. The B label shows the supply of implants. Label C shows the supply of injectables. Label D shows the supply of intra-uterine devices (IUDs). Label E shows the supply of oral contraceptive pills.
