Background information Edit
It is not explicitly stated how these designations were assigned, though it is generally assumed that they were simply incremental, each newly encountered species getting a number one higher than the previous. This mostly holds up when comparing numbers to probable first contact dates or vicinity to Borg space, though some anomalies exist, most notably the Alpha Quadrant species Ferengi having an unusually low number of 180; this may suggest that at least one Ferengi ship had visited the Delta Quadrant and encountered the Borg early on in the Borg's expansion. The species-designation numbers all appear to have been assigned at first contact, and appear not to have been reused even after the whole species was assimilated.
Not enough is known about this practice to identify "Species 1" or "Species 0." Nor is the Borg's species-designation number for themselves, or even whether they have actually assigned themselves any such numbers, known.
