Thousands of people will take to the streets of New York Sunday for the city's annual Hispanic Day Parade up Fifth Avenue. The popular parade is in its 51st year of celebrating solidarity among the city's diverse Hispanic populations, numbering more than 2.4 million, according to AM New York.

While thousands of spectators are expected to attend this year, up to 1 million marched in the 2014 parade to mark its 50th year. The parade falls toward the end of Hispanic Heritage Month, which runs from Sept. 15 to Oct. 15. 

Marchers will represent Spanish-speaking countries in Central and South America, as well as Cuba, the Dominican Republic, Puerto Rico and Spain. The groups at the parade will include Hispanic associations, as well city departments, such as the New York City Police Department and the New York City Fire Department.

"I always look forward to representing my nationality," Joe Maldonado, who is of Puerto Rican descent and has marched in the parade for 45 years, told AM New York. "It's a very colorful parade. Every country, they all come in their native clothes." Maldonado is president of the Department of Sanitation's Hispanic Society, which will feature dozens of members in the parade. 

This year's parade will also highlight marshals representing each country. Miss Universe Paulina Vega, from Colombia, will be a special guest.
