The second-largest business district in terms of employment is La Défense, just west of the city, where many companies installed their offices in the 1990s. In 2010 it was the workplace of 144,600 employees, of whom 38 percent worked in finance and insurance, 16 percent in business support services. Two other important districts, Neuilly-sur-Seine and Levallois-Perret, are extensions of the Paris business district and of La Defense. Another district, including Boulogne-Billancourt, Issy-les-Moulineaux and the southern part of the 15th arrondissement, is a center of activity for the media and information technology.
