1. The USA
Number of teen pregnancies: 614,000
If you have already been familiar with the matter, then you definitely saw the US coming to the top of 13 countries with the highest teenage pregnancy rates in developed world. While Vox and other media are full of praise for teen birth rates plummeting, we deem it best to wait for a full report on pregnancies. A drop in births can mean there were simply more abortions, and not guarantee that fewer teen girls are becoming pregnant.
