Do the new common core standards for math actually lead to better outcomes long term?

I keep hearing about common core and how math is being taught now, and I am not really looking for opinions with this Q, but hard data.

Has this method demonstrated long term (post high school graduation) the now adults are more competent in math and more likely to pursue careers and college degrees that require more advanced math?

I do also wonder if kids while learning these methods in elementary school show a greater competence and even inclination for math than previous generations, but long term affects would be the biggest concern.

This is basically about the US, but if the same methods have been done in other countries and there is data that does interest me. Possibly, other countries have been using these methods for a long time and have significantly more data.
