Crime Statistics Act (P.L. 101–275), in order to develop a systematic approach for documenting and understanding hate crimes against LGBT people in the United States. The Federal Bureau of Investigation (FBI) has also implemented a data collection program and integrated the system under their Uniform Crime Reporting (UCR) program and National Incident-Based Reporting System (NIBRS). Federal hate crime statistics In 2014, the Federal Bureau of Investigation (FBI) reported that 20.8% of hate crimes reported to police in 2013 were founded on perceived sexual orientation. Sixty-one percent of those attacks were against gay men. Additionally, 0.5% of all hate crimes were based on perceived gender identity. In 2004, the FBI reported that 14% of hate crimes due to perceived sexual orientation were against lesbians, 2% against heterosexuals and 1% against bisexuals. The FBI reported that for 2006, hate crimes against gay people increased from 14% to 16% in 2005, as percentage of total documented hate crimes across the U.S. The 2006 annual report, released on November 19, 2007, also said that hate crimes based on sexual orientation are the third most common type, behind race and religion. In 2008, 17.6% of hate crimes were based on the victim's perceived sexual orientation. Of those crimes, 72.23% were violent in nature. 4,704 crimes were committed due to racial bias and 1,617 were committed due to sexual orientation. Of these, only one murder and one forcible rape were committed due to racial bias, whereas five murders and six rapes were committed based on sexual orientation. Santa Clara County Deputy District Attorney (DDA) Jay Boyarsky attributed a surge in anti-gay hate crimes, from 3 in 2007 to 14 in 2008, to controversy over Proposition 8. However, the DDA cautioned against reading too much from small statistical samples, pointing out that the vast majority of hate incidents do not get referred to the District Attorney's office. In 2011, the FBI reported 1,572 hate crime victims targeted based on a sexual orientation bias, making up 20.4% of the total hate crimes for that year. Of the total victims. 56.7% were targeted based on anti-male homosexual bias, 29.6% were targeted based on anti-homosexual bias, and 11.1% were targeted based on anti-female homosexual bias. The United States, however, does not make reporting on hate crimes mandatory, meaning the FBI data gathered over the years is not an accurate representation of the correct number of hate crimes against LGBT Americans.
