Lab Four - Pre-processing Census Data

In this lab we prepared tabular data about county-level population data of US census from 1900 to 2000. I choose the state of Montana (MT). I've never been there, but I really liked some movies that played there, like Open Range (although that one was completely filmed in Canada...). Well, you can find your own favourite Montana Film here, but anyways: the Rockies are there!

But because the data is not really interesting yet (I just created a shape file with the state's counties and calculated the population changes as attributes), nothing to see here but the flag of Montana and a screenshot of my Montana shape file.
