Absolute dumbest question so be gentle

Hi, I'm doing some research analysing legal statutes of incorporation. The total population of corporations is 2,454 in 8 jurisdictions. If I do the online sample size calculator set at 99% confidence with 2% margin of error I get a required sample size of 1,544 BUT if I apply the same to each jurisdiction and then total the required sample size becomes 2175. Can someone explain and which way should I go?
