Comparison of stellar populations between the AGN and inactive sample where the inactive sample is split by location on the BPT diagram into a star-forming (SF) sub-population and a non-star-forming (non-SF) sub-population. The stellar populations are split into the same four age bins as in the previous section: young (blue), young-intermediate (green), intermediate-old (yellow), and old (red), with boundaries at log(age/yr) = 7.5, 8.5, and 9.5. The AGN-hosting galaxies are sorted by increasing X-ray luminosity L_X, and the inactive control population is sorted by increasing equivalent width of Hα (EQW(Hα)).
