2010 Apportionment Projections by Experts
If you do not want to fiddle with the apportionment calculator, take a look at some apportionment projections. Notice that sometimes the experts have more than one prediction. They also do not always agree with each other. You will have to make a choice.
Population Estimates - Census Bureau and ESRI
These estimates or some modification of them are a good starting point for input to the apportionment calculator. The ESRI estimates are included in this table, because this is the source for the latest projections by Election Data Services. For simplicity, Washington, DC - Taxation Without Representation - has been excluded.
*The winners are defined on the basis of the counts that the Census Bureau sends to Congress. There are likely to be challenges to these, but the litigation can take years.
