Thanks all. I should have been more specific about the data. I'm testing a subset if my panel which actually has 49 counties overall. I realize that testing a subset this small may just be put if the question unless I have more years to test. Thanks to all for the suggestions.

I have tried running the panel regression using the xtreg, re command as well as regress with the vce (cluster county) command. The problem is that neither command is producing standard errors (there's just a . in the standard error column). Essentially the model is useless. For some reason when I run either type of model (regress of xtreg), STATA assumes I only have 5 observations when in reality I have 25 (5 years for 5 counties). How can I get STATA to recognize the panel nature of my data? I have also tried adding year dummies to the model to no avail. Does anyone have suggestions?
