At the expiration of their prison term, most inmates return to society and try to resume their lives. Around 450,000 inmates are either released on parole or complete their term of parole each year. The total parole population each year is around 850,000

In a document report the changes you found from the E-textbook Figure 14.1 Parole Entries &
Exists 2000-2014 verse the attached 2020 Report.

An estimated 3,890.400 adults were under community supervision at yearend
2020, which was a 6.6% decline from
the 4,167,100 who were supervised in the community on January 1, 2020 (figure 1). 1
This decline was solely driven by a reduction in people on probation, who made up the majority (79%) of the community supervision population.
During 2020, the number of people on probation decreased from 3,330,200 to 3,053,700 (down 8.3%), the largest annual decline since the Bureau of Justice Statistics (BIS) began the probation collection in 1980 (not shown).
The number of adults on parole increased 1.3% during 2020, from 851,000 on January 1, 2020 to 862,100 at yearend. Among all adult U.S. residents, 1 in 66 were supervised in the community at yearend 2020.

From the E-textbook Figure 14.1, we can see that the total parole population in 2000 was around 450,000, which is significantly lower than the 862,100 adults on parole at yearend 2020. This indicates a substantial increase in the number of individuals under parole supervision over the past two decades.

Additionally, the E-textbook Figure 14.1 shows that the number of individuals released on parole or completing their term of parole each year was around 850,000. In contrast, the 2020 report states that there were 862,100 adults on parole at yearend 2020, which suggests that the number of individuals entering or exiting parole supervision each year may have decreased over time.

Overall, the comparison between the E-textbook Figure 14.1 and the 2020 report highlights a significant increase in the total parole population, as well as potential changes in the rates of entry and exit from parole supervision over the years.
