Find population of buffered area (over a census tract layer)

Is there a tool that can measure the population based on the area covered by only the buffered portion over a census tract layer (see pic)?

On the pic, you'll see that the buffered areas covers some portions of each tract. So, if a particular tract has 100 people in it, but the buffered portion of the tract covers 60% of that tract, then of course, the mean population is 60 people.

But I would have to do the math for every tract/buffer (I have a lot of them). Is there a tool that can first figure out how much area my buffer covers with each tract, and then figure out the resulting population covered by each buffer?

Or, was using the Buffer tool the right choice to begin with (assuming there is a smarter tool)?
Thanks
Mark
