Immigrants tend to concentrate and have a disproportionate impact on some metropolitan areas,
most often identified as "gateway cities." Yet many other metropolitan areas are facing a major
influx of immigrants, both legal and illegal.
Below is a listing of metropolitan areas for which immigration data is available, listed by state (although, sometimes the metro areas cross state boundaries). Those metro areas that are in bold are
ones which include INS data on recent immigrant settlement. The other metro areas
include only data on sources of population change since 1990 (through 1997), to show the
relative importance of net international migration.
Note: The boundaries of the metro areas in this section are those established by the US Office of Management and Budget for 58 primary statistical areas (PMSA's) or smaller metropolitan statistical areas (MSA's).
