Abortion...very interesting

This is actually one of my crosstabs for my project but i found it very interesting that the r squared value was very weak. I thought for sure that abortions per 1000 woman would have some kind of connection with birth to teen mothers. The reason i felt this way is because some teens bodies arent fully developed enough to give birth to a baby and also most teens arent financially stable enough to take care of a child so the abort the pregnacy.
