At the 2011 census, there were 1,729,040 people with 906,782 households living in Budapest. Some 1.6 million persons from the metropolitan area may be within Budapests boundaries during work hours, and during special events. This fluctuation of people is caused by hundreds of thousands of suburban residents who travel to the city for work, education, health care, and special events. By ethnicity there were 1,397,851 (80.8%) Hungarians, 19,530 (1.1%) Romani people, 18,278 (1.0%) Germans, 6,189 (0.4%) Romanians, 4,692 (0.3%) Han Chinese and 2,581 (0.1%) Slovaks. 301,943 people (17.5%) did not declare their ethnicity. In Hungary people can declare more than one ethnicity, so the sum of ethnicities is higher than the total population. The city is home to one of the largest Jewish communities in Europe.
