Corporations never increase

I have 46 corps- I keep building more and should have about 80 my unemployment goes down, my world standing goes up, my income goes up migration is steady, I am operating well in the black, but the number never changes is there a cap on corporations? or what might I be doing wrong any clues anyone?

If you could let me know what world you're on I can take a closer look at the information in your country and see if I can't help get to the root of the issue you're facing.
