Irish Americans

Gearing up for March 2020, the Census released a short history lesson on St. Patrick's Day:

"Originally a religious holiday to honor St. Patrick, who introduced Christianity to Ireland in the fifth century, St. Patrick’s Day has evolved into a celebration of all things Irish.

"The world’s first St. Patrick’s Day parade occurred on March 17, 1762, in New York City, featuring Irish soldiers serving in the English military. This parade became an annual event, with President Truman attending in 1948."

They also shared these amazing facts about the Irish American community in the United States:

  • 32 million Americans claim Irish ancestry.
  • 9.9% of all of the Presidents of the United States have claimed Irish heritage.
  • 123,950 - The number of foreign-born U.S. residents who reported Ireland as their birthplace in 2018.

Irish American Heritage Month

Back in 1991, the United States Congress proclaimed that every March be celebrated as Irish American Heritage Month and every year the President of the United States issues a proclamation commemorating the occasion. 

In the 2019 proclamation, President Trump's proclamation stated: "During Irish-American Heritage Month, we celebrate the indispensable contributions Irish Americans have made to every chapter of our Nation’s history.  Generations of Irish immigrants have carried to our shores character, culture, and values that continue to play pivotal roles in the strength and success of America."

He added "Today, more than 31 million Americans look back with pride on their Irish heritage and the legacy of their ancestors.  The faith, perseverance, and spirit of Irish Americans across our country is indelibly woven into the tapestry of the American story.  As we spend this month honoring the incredible history of Irish Americans, especially on St. Patrick’s Day, we look forward to a bright future of continued friendship and cooperation between the United States and Ireland."
