The percentage of immigrants in New York City’s population is the highest it’s been in a century.

That’s according to a city report issued Wednesday.

The report says there were just over 3 million foreign-born residents in 2011, out of a population of 8.2 million.

That makes immigrants 37.2 percent of city dwellers.

The last time the city had a higher share of immigrants was in 1910, when 41 percent of residents were foreign-born.

The lowest was in 1970, when 18 percent of residents were immigrants.

The largest groups of foreign-born residents are from the Dominican Republic, followed by China and Mexico.

Experts from the Department of City Planning analyzed US Census data. The last edition of the report was released in 2005.
