Agricultural, Geographic and Population data for Counties in the Contiguous United States

Annual crop data from 1972 to 1998 are now available on
EOS-WEBSTER. These data are county-based acreage, production, and
yield estimates published by the National Agricultural Statistics
Service. We also provide county level livestock, geography,
agricultural management, and soil properties derived from datasets
from the early 1990s.

The National Agricultural Statistics Service (NASS), the statistical
arm of the U.S. Department of Agriculture, publishes U.S., state, and
county level agricultural statistics for many commodities and data
series. In response to our users requests, EOS-WEBSTER now provides 27
years of crop statistics, which can be subset temporally and/or
spatially. All data are at the county scale, and are only for the
conterminous US (48 states + DC). There are 3111 counties in the
database. The list includes 43 cities that are classified as
counties: Baltimore City, MD; St. Louis City, MO; and 41 cities in
Virginia.

In addition, a collection of livestock, geography, agricultural
practices, and soil properties variables for 1992 is available through
EOS-WEBSTER. These datasets were assembled during the mid-1990's to
provide driving variables for an assessment of greenhouse gas
production from US agriculture using the DNDC agro-ecosystem model
[see, for example, Li et al. (1992), J. Geophys. Res., 97:9759-9776;
Li et al. (1996) Global Biogeochem. Cycles, 10:297-306]. The data
(except nitrogen fertilizer use) were all derived from publicly
available, national databases. Each dataset has a separate DIF.

The US County data has been divided into seven datasets.

US County Data Datasets:

1) Agricultural Management
2) Crop Data (NASS Crop data)
3) Crop Summary (NASS Crop data)
4) Geography and Population
5) Land Use
6) Livestock Populations
7) Soil Properties
