The average prison population during 1992, including the average of 1,100 in police cells, was 45,800, a decline of 100 from 1991. The seasonally adjusted population at the end of the year was 42,300, nearly 5,000 lower than the previous year and the lowest monthly figure since September 1984. The remand population remained steady at approximately 10,600, while the sentenced population rose from 36,300 at the end of 1991 to 36,700 at the end of April 1992; at that point, it decreased to 32,800 by December 1992. These reductions in the sentenced and remand populations were due to the advancement of releases on parole and the introduction of the Criminal Justice Act 1991. 6 tables, 7 figures, and 14 notes
