costs, most notably seen in the 10% average increase in state prison budgets from 2005 to 2006. The SLC expects the percentage of elderly prisoners relative to the overall prison population to continue to rise. Ronald Aday, a professor of aging studies at Middle Tennessee State University and author of Aging Prisoners: Crisis in American Corrections, concurs. One out of six prisoners in California is serving a life sentence. Aday predicts that by 2020 16% percent of those serving life sentences will be elderly. State governments pay all of their inmates' housing costs which significantly increase as prisoners age. Inmates are unable to apply for Medicare and Medicaid. Most Departments of Correction report spending more than 10 percent of the annual budget on elderly care. The American Civil Liberties Union published a report in 2012 which asserts that the elderly prison population has climbed 1300% since the 1980s, with 125,000 inmates aged 55 or older now incarcerated. LGBT people LGBT (lesbian, gay, bisexual, or transgender) youth are disproportionately more likely than the general population to come into contact with the criminal justice system. According to the National Center for Transgender Equality, 16 percent of transgender adults have been in prison and/or jail, compared to 2.7 percent of all adults. It has also been found that 13–15 percent of youth in detention identify as LGBT, whereas an estimated 4–8 percent of the general youth population identify as such. The reasons behind these disproportionate numbers are multi-faceted and complex. Poverty, homelessness, profiling by law enforcement, and imprisonment are disproportionately experienced by transgender and gender non-conforming people. LGBT youth not only experience these same challenges, but many also live in homes unwelcoming to their identities. This often results in LGBT youth running away and/or engaging in criminal activities, such as the drug trade, sex work, and/or theft, which places them at higher risk for arrest. Because of discriminatory practices and limited access to resources, transgender adults are also more likely to engage in criminal activities to be able to pay for housing, health care, and other basic needs. LGBT people in jail and prison are particularly vulnerable to mistreatment by other inmates and staff. This mistreatment includes solitary confinement (which may be described as "protective custody"), physical and sexual violence, verbal abuse, and denial of medical care and other services. According to the National Inmate Survey, in 2011–12, 40 percent of transgender inmates
