The following is a list of the twenty largest metropolitan areas in 2003 as defined by one source. As population figures are interpreted and presented differently according to different methods of data collection, definitions and sources, these numbers should be viewed as approximate. Data from other sources may be equally valid but differ due to being measured according to different criteria or taken from different census years.
|Rank||Metropolitan area||Country||Population||Area (km2)||Population Density (People/km2)|
|4||New York City||USA||19,750,000||17,884||1,104|
