I believe Stephen is thinking of initial allocation policy - because a
subsequent allocation policy in the ARIN region exists: (and it's been
modified atleast once in the last few years)
Justification to obtain another netblock is .94 HD-Ratio in the
current allocation
Endusers (minimum allocation is a /48)
For a /48 that's about 72% utilization or 184 /56's assigned/used
ISP's (minimum allocation is a /32)
For a /32 that's about 37% utilization or 6,183,533 /56's assigned
ARIN provides a handy chart:
