The Smithsonian Institution’s federal appropriation will increase $14.5 million to $819.5 million for the fiscal year that started Oct. 1, officials said.

Most of the money — more than $675 million — will cover salaries and expenses at the institution, including a federal pay raise of 1 percent and increases in employee benefits and other costs.

The appropriation — a small piece of the omnibus package Congress passed earlier this month — includes $6.5 million for staffing, programming and collections care for the National Museum of African American History and Culture and the final $24 million of the federal government’s commitment for its construction.
