How many births were there in the United States in 1980?

The United States has dozens of major cities, including 11 of the 55 global cities of all types—with three "alpha" global cities: New York City, Los Angeles, and Chicago. The figures expressed below are for populations within city limits. A different ranking is evident when considering U.S. metro area populations, although the top three would be unchanged. The 10 largest cities, based on the United States Census Bureau's 2005 estimates, are as follows. In historic areas that were settled very early, e.g., Boston, New Haven, etc., the boundaries were set in the 1700s and therefore the populations appear small even though, in actuality, the cities are very large.
