Once a center of poor and working-class Irish Americans, over the last three decades of the 20th century and into the new millennium, Hell's Kitchen has undergone change as a result of its location at Midtown. The 1969 edition of the "Plan for New York City" book, authored by the City Planning Commission, stated that people of modest means were being driven from the area by development pressures due to the Midtown location. Today, many actors live in the neighborhood due to its closeness to the Broadway theaters and Actors Studio training school.
