Looking at the occupancy stats, it shows that US prison are also overcrowded, with an occupancy percentage 107.6%.
This is not as bad as some countries, but any overcrowding is bad - it points to one of two reasons:
1) There are not enough prisons
2) Crime rate has increased above predicted levels (for whatever reason).
It seems clear in this case that more offenses are considered worthy of jail time - i.e. crime rate has increased.
Some more Dept of Justice stats:
# In 2005, over 7 million people were on probation, in jail or prison, or on parole at yearend 2005 -- 3.2% of all U.S. adult residents or 1 in
every 32 adults.
# State and Federal prison authorities had in custody 1,446,269 inmates at yearend 2005: 1,259,905 in State custody and 179,220 in Federal custody.
# Local jails held 747,529 persons awaiting trial or serving a sentence at midyear 2005. An additional 71,905 persons under jail supervision were
serving their sentence in the community.

Between yearend 1995 and yearend 2005, the incarcerated population grew an average 3.3% annually. Population growth during the 12-month period
ending December 31, 2005 was lower in State prisons (up 1.3%) than in Federal prison (up 5.1%) and local jails (up 4.7%).

Now, if I'm right in saying that federal prison is (in general) for more serious crimes, then this would seem to indicate an increase in crimes
viewed as being more serious.
These tables are also quite telling:

These figures would suggest that re-offending is a major problem, in which case (according to liberal suggestions) there is little in the way of
rehabilitation, and that incarceration is seen only as a punishment, rather than an opportunity to re educate prisoners not to re offend.
I think this shows that just locking people up with no effort to rehabilitate causes more problems than it solves.
One of the reasons for the very high prison levels is the rate at which people re-offend, some of which can be blamed on lack of rehab.
Of course there are still career criminals who will choose no other path, but perhaps the prison levels could be lowered using a programme of rehab
and education.
