A Migrating Population - Using IRS Data to Track Movement Patterns

Understanding the ebb and flow of where people move across the country is crucial to making critical site location decisions. That is why we utilized the latest available IRS data to determine where and from people are moving. We are also able to determine average household income from aggregate income data to understand where higher incomes are moving. The need for past migration trends is more important now more than ever, and something we have commonly been asked about in regards to the COVID-19 pandemic.
