The department's annual report said the number of prisoners increased by more than 96,000, or nearly 5 percent, from July 1, 1996, to June 30, 1997. On June 30,there were nearly 1.1 million state prisoners, more than 560,000 local-jail inmates and more than 99,000 federal prisoners. The report said the steepest increase took place in local jails, which held about 9,100 juveniles. The number of jail inmates jumped 9.4 percent, almost double its average annual increase since 1990 of 4.9 percent, while the number of state and federal prisoners rose only 4.7 percent, less than its annual average since 1990 of 7.7 percent. The largest jail populationwas in Los Angeles County, with 21,900 inmates.New York City had 17,500 inmates. Since 1990,the number of people in custody has risen by more than 577,000 inmates. The report found that one of every 155 U.S. residents was behind bars in mid-1997 The trend of more incarcerated criminals dates back to 1980. The report gave no reason for the increase in the prison population, but experts have cited a number of factors, including tough new sentencing laws and more drug arrests.
