Unlike the yearend 2001 prevalence rate of 2.7%, which represents the

cumulative result of the past incarceration experiences of the living

adult population, the lifetime likelihood is a hypothetical projection

of the future if a birth cohort were to experience a fixed set of rates

of first incarceration and mortality over a lifetime.

Between 1974 and 2001, the lifetime chances of going to State or

Federal prison for U.S. residents overall in- creased from 1.9% to

6.6%. Each estimate summarized the effects of first incarceration and

mortality during a 12-month period in 1974, 1986, 1991, and 2001. The

estimates do not take into account changes in rates of first

incarceration or mortality that occur after the "birth" of the

hypothetical cohort. As a result of steadily rising rates of first

incarceration from 1974 to 2001, the lifetime chances of going to

prison for persons born in 1974 will be higher than 1.9%. Based on

rates of first incarceration through 2001, an estimated 2.6% of persons

born in 1975 had already been incarcerated by age 25.

+6 times higher lifetime chance of going to prison in 2001 for men than

for women+

Based on rates of first incarceration in 2001, the lifetime chances for

men of going to prison are 6 times greater than those for women (table

9). A male has a 11.3% (or 1 in 9) chance in his life-time of going to

prison, while a female has a 1.8% (or 1 in 56) chance. An estimated

9.6% of men and 1.5% of women are expected to go to prison by age 40,

as first incarceration rates riserapidly, then decline with advancing

age (figures 4 and 5).

Estimates were obtained by applying age-specific first incarceration

and mortality rates for each group to a hypothetical population of

100,000 births. See _Methodology_.
