Given that the mapping tools were only recently updated with the official population data, any maps submitted using the estimated population data may not be population balanced according to the official population data, even if they appeared to be so according to the estimated population data.
If you submitted a CSV file or paper map, you can send an email seeking confirmation that it is indeed balanced.
If you submitted through DistrictR or MOR ID, you can open the Plan Summary Table to see if your map is actually balanced. If the far right column says “Yes,” then you do not need to modify your original submission to make it balanced; it already is. If that column gives a percentage value, then that means your map is not balanced, because that value needs to be less than 10%.
