The natural amenities scale is a measure of the physical characteristics of a county area that enhance the location as a place to live. The scale was constructed by combining six measures of climate, topography, and water area that reflect environmental qualities most people prefer. These measures are warm winter, winter sun, temperate summer, low summer humidity, topographic variation, and water area. The data are available for counties in the lower 48 States. The file contains the original measures and standardized scores for each county as well as the amenities scale.

Migration data for the United States are based on year-to-year address changes reported on individual income tax returns filed with the IRS. The data present migration patterns by state or by county for the entire United States and are available for inflows (the number of new residents who moved to a county or state and where they migrated from), and outflows (the number of residents leaving a county or state and where they went). The data are available for returns filed in 2004 through 2010 and include: • Number of returns (which approximates the number of households that migrated) • Number of personal exemptions (which approximates the number of individuals who migrated) • Total adjusted gross income of the migrants It is important to note that the data used to produce migration data products come from individual income tax returns filed prior to late September of each calendar year and represent between 95 and 98 percent of total annual filings. However, since returns filed after September are not included, totals shown in migration data tables will not match analogous totals reported in other IRS statistical data products.

Geographic migration statistics, based on alternate data sources, are also produced by the Census Bureau.
