Rockingham County, Virginia (not including the City of Harrisonburg) is comprised of (approximately) 46,600 parcels of real estate.  Some of these lots or tracts are very small, in towns such as Grottoes, Dayton or Elkton.  Others are quite expansive and are in the far flung corners of the County.  Below is a visual representation of the distribution of lot sizes of those 46,600 properties --- you might need to click on this link to view the full size document for easier reading.


Here's the summary:

• 20,108 parcels less than a half acre
  
• 6,889 parcels of 0.5 - 1 acre
  
• 9,801 parcels of 1 - 5 acres
  
• 5,513 parcels of 5 - 20 acres
  
• 2,355 parcels of 20 - 50 acres
  
• 1,933 parcels of 50+ acres

There is quite a bit more to break down from this data set, but here are a few interesting surface level observations:

• Almost half (43%) of the parcels in Rockingham County are less than a half acre
  
• 79% of the parcels in Rockingham County are less than 5 acres
  
• There are a lot (1,933) of large tracts of land (50+ acres) left in Rockingham County

And the most interesting facts I've gleaned from this data thus far revolve around the largest parcels in Rockingham County:

• The largest parcel in Rockingham County is owned by the (and is the) U.S. National Forest, with a size of 140,001 acres.
• The second largest tract is 37,980 acres, and owned by the U.S.Department of the Interior --- I'm guessing this is also National Park land...
  
• These two largest parcels combined encompass one-third (33%) of the total acreage of Rockingham County.
• The combined value of these two parcels (though I doubt they pay property taxes!?) is roughly $186 million!
