1. The name of the current state, table name, and data item being displayed.

2. Control panel allows users to change the data item and state being displayed as an SVG map.

3. By placing the cursor over a state or county, the name and published data for that area is displayed on the right side of the map.

4. Displays the name of the area and total for a selected data item that is being moused-over on the map.

5. The range controls allow users to change the map color and the number of displayed comparisons. Users may also change the data range to reflect a national or state level.

Due to the way the data ranges are calculated, in certain cases, the state and national range will be the same.

6. The legend displays both the data range, and the color range, allowing users to make state by state or county by county visual comparisons on the SVG map.

Published data is not always available for each state or county. In some instances, the total for an area is zero.
The following is a list of definitions and symbols used when published data is not available:
(D) Withheld to avoid disclosing data for individual farms
(NA) Not available or not published. Some historic data are not published because they are not comparable, electronic files are unavailable, or resummarizing could compromise respondent confidentiality
(X) Not applicable
(Z) Less than half of the unit shown.
7. The download buttons allow users to either view and print PDF tables of the available data for each state, or download XML or CSV files to be used in spreadsheets or other user applications.
