Discrimination against transgender people is costing New York millions, according to a new report. The study, released yesterday by the UCLA’s Williams Institute, says that housing and employment discrimination cost the state millions of dollars as people lean on public assistance instead. According to the study, workplace discrimination could cost the state about $7 million each year. The report estimates about 58,000 New Yorkers are transgender, and said 59 percent are covered under local anti-discrimination statutes. But that leaves about 23,800 people unprotected, according to the study.
