More than 550 organizations participated in last year’s Pride March, and it’s likely to be even bigger this year: According to the NYPD, an additional three to four million people are expected to head to the various Pride festivities happening over the weekend (and spilling over into next week, when the Fourth of July happens). This year’s NYC Pride March promises to be one of, if not the, biggest events of the year: For the first time, New York is playing host to WorldPride, the annual celebration of LGBTQ communities around the world.
