Visualizing the U.S. Federal Prison Population by Types of Offenses (April 2009)

(Click on image for dynamic chart.)

This chart shows the types of offenses under which the U.S. federal prison population (205,096) was sentenced.

The big fat light-blue bubble is Drug Offenses, 350% larger than the next highest category (Weapons, Explosives and Arson).

Data came from the Federal Bureau of Prisons, and the data visualization was made using Many Eyes.

Internet Usage in Europe

Thanks to an excellent eMarketer newsletter article, Russian Online Population Explosion, I had important data to import into Many-Eyes.com.

Europe's 2007 Internet usage by % of population is 37%.

Russia's % of population is only 12%, but is expected to increase to 43% by 2012.

Visualizing Overcrowded Prisons

The data for this visualization is from the
Department of Corrections and Rehabilitation, State of California.

California's 2008 data is due out in July 2008. Prison overcrowding is expected to increase even more.

Prisons and the Need for Prison Reform

To better represent statistics available through the PEW Charitable Trusts or government organizations such as the U.S. Census Bureau and Bureau of Justice Statistics, I use Many-Eyes. Many-Eyes is a powerful visualization tool for all on the Internet. Prison data is under my topic hub called, Prisons and Prison Reform.

A few significant facts among the charts and graphs:

• From 2000 to 2005, felony arrests in California increased 17%.
• More than half the California prison institutions/camps are occupied at over 200% of the capacity for which they were designed, and all are over 100%.
• In French Guiana, prison occupancy is at 469% of prisons' designed capacities.
• Prison incarceration rate in the state of Louisianna is 835 per 100,000 population. It's the highest in the U.S. and higher than any country in the world.

And here is a U.S. map showing States' ratios of blacks (%) in prison to blacks (%) by population.
