About the Data: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. Thus 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.

• Story No. 18993: The Census 2000 Supplementary Survey shows trends in migration by immigrants and domestic migrants (newcomers from other parts of the US). Regions not attracting either group have often experienced a prolonged economic decline or lack natural or cultural amenities that many migrants seek. California has the largest number of foreign-born residents, while Western and Southeastern states tend to attract many domestic migrants. States in the Midwest, Northeast and parts of the South have few migrants and tend to have older, less diverse populations.
• Story No. 21437: This article uses mapping software and census data to show new patterns in the movement of minority groups. A county by county analysis shows what motivates certain groups to move to certain places.
• Story No. 16677: The Syracuse Newspapers devoted five years to this eight-part series examining the migration trend out of Syracuse to other parts of the country in search of better employment opportunities. The series takes an in-depth look at the impact of the economic recovery of the early 1990's and the resulting population shift across the country.
• Story No. 17357: 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..."
