One of the key components for estimating migration impacts on population are IRS records. As people move and relocate, IRS records are used to track their entry into, or exit from, communities. The graph below shows the net gains and losses for Herkimer County based on these records.One thing to note: the 2012 data was tabulated in a manner considerably different than that of previous years.
In prior years the filer's ID was track and population migration was attributed based on previous household information. In 2012, as an effort to get more accurate data, not only is the filer's ID tracked, but also their dependents, thereby providing a more precise picture of how many people in a household may have relocated from one community to another.
