m.tiger.region problems

Hello,

m.tiger.region gives me the following output when I feed it a TIGER type 1 file
that consists of county boundary lines (or similar output for the whole type 1
file):

Number of calculated zones is: 2

INFO FOR ZONE 1:
  zone number: 11
  percentage of data points
  in this zone: 0.748663
  regional spread of points
  within this zone:
    north: 3853573.837800
    south: 3755384.454505
    east: 439514.899932
    west: 330790.050964

INFO FOR ZONE 2:
  zone number: 0
  percentage of data points
  in this zone: 99.251335
  regional spread of points
  within this zone:
    north: 0.000000
    south: 0.000000
    east: 0.000000
    west: 0.000000

It seems a bit strange for 99% of the data points to be located nowhere,
doesn't it? Any suggestions?

Thanks
Eric Kostello
