Description

The decennial census provides all sorts of interesting morsels that can be passed on to readers, viewers, or listeners. But there is one item the census does not cover: where the people in your community are coming from and where are they moving to. With the IRS migration data, you can track movement in and out of counties. Moreover, financial information in the data allows you to gauge whether your community is gaining or losing wealth. This data – which is processed through a cooperative agreement between the IRS and the Census Bureau – makes a perfect complement to other census data. The Census Bureau compiles the dataset by matching the Social Security number of the primary taxpayer from one year to the next. If the address for that taxpayer changes, they are considered migrants.

  • Boom on the beach
    This USA Today series analyzes the economic growth and development along East and Gulf Coasts and draws the conclusion that “41 million people – more than one in seven Americans – live in a county on the Atlantic Ocean or the Gulf of Mexico.” The analysis of population and demographic trends, and building permits, finds that “coastal counties are growing significantly faster than the rest of the country in population, employment and gross domestic product.” The boom among 100 coastal counties is illustrated with maps, graphics and tables. The series reveals that in spite of multiple natural threats – like long-term hurricane risk, rising sea level, fragile sands and erosion – “growth pressure keeps building” and “all levels of government foster this amenity-driven, middle-class lifestyle…”
