We use the CrAO catalog of the magneto-morphological classes (MMC) of active regions (ARs) to study the hemispheric distribution of the number and magnetic fluxes of ARs that appeared on the disk from May 1996 to December 2021. 3047 ARs were distributed between classes of the regular (bipolar groups that obey empiric rules for sunspots) and irregular (all the rest, except for unipolar sunspots) ARs. The analysis of the results showed that all the trends are more pronounced in the flux data. For the irregular ARs, the strongest peaks in time profiles are observed in the second maximum of the cycle in the S-hemisphere. ARs of both MMC types demonstrate noticeable N-S asymmetry. The most abrupt changes are shown by the irregular ARs fluxes. For the compiled quadrupolar-like component of the flux, the evidence of oscillations with a period of about 15 years is found for all studied ARs and for the irregular groups. For the regular ARs, cross-correlation of ARs fluxes in different hemispheres in adjacent cycles showed no features. For the irregular groups, a high correspondence in flux dynamics in the N-hemisphere of cycle 23 and in the S-hemisphere of cycle 24 is found.
