i have information about the population in a city and the master plan of it, and want to make a new master plan for areas of expansion in this city through the coming years, that is by comparing the supposed population in each zone of the master plan and the existing population, if the supposed population is the larger then no need to change it but if the opposite then it should be considered as a place for expansion, after all the zones are filled i should choose new places for the expansion, but i don`t know how to use if statements in ArcGIS
