FAQ’s
There is a link that will open the Appendix A of the TIGER/Line Technical
Documentation PDF; this documents lists all the counties, by state, and the codes for
each. The PDF will open in the browser window. Scroll through the document until you find
the codes for your county and state.
Make a note of each county’s 5-digit number - this includes the state code. When finished,
click the Back button on the browser to get out of the PDF document. (If you close the
PDF, you will close the Internet.)
You will be back on the same page that had the Documentation section mentioned earlier.
Scroll down that site until you get to the section at the bottom that lists all the states. You
are now ready to download the data.
Begin by clicking on the state that the farm resides in. A list of all the counties will open.
Using the numbers you found in the State and County Codes and Names PDF, locate
the county you want to download. If your farm is part of multiple counties, you will need to
repeat this process for each county; each one as they will form a composite TIGER data
layer on the farm map.
For this example, we are downloading Illinois’ Rock Island county. We know
from the state and county code names that Illinois is 17 and Rock Island
county is 161. So we need to scroll through this list until we reach
TGR17161.ZIP.
