Buffalo, which was the eighth-largest city in America slightly more than a century ago, now ranks 70th, based on new figures released Tuesday by the U.S. Census Bureau.
Buffalo's population was 270,240 on July 1, 2009, according to the bureau's latest round of estimates. That's down from 292,648 in 2000, when the previous decennial census was conducted. Buffalo was then the 59th-largest city in the country.
Results of the 2010 census, which was conducted in April, will not be released until early next year.
The new estimates cover 19,510 incorporated places across America, including all 618 cities and villages in New York. The Census Bureau does not consider New York's towns, including such populous communities as Amherst and Cheektowaga, to be incorporated places.

New York City, with an estimated 2009 population of 8.39 million, easily remains the largest city in America. It's followed by Los Angeles (3.83 million), Chicago (2.85 million) and Houston (2.26 million). All hold the same ranks now as in 2000.
The only newcomer in the top 10 is San Jose, which was 11th in 2000. It now occupies 10th place on the list of America's largest cities, supplanting Detroit, which has slipped to 11th place.
New York City registered the largest raw gain of any city between 2000 and 2009, increasing its population by 383,195 in nine years. The four runners-up are all in the Southwest: Houston (up 284,199 since 2000), Phoenix (up 279,149), San Antonio (up 213,752) and Fort Worth (up 184,237).
All figures in the new Census Bureau report are solely for cities, villages, and other incorporated places -- and are not for metropolitan areas as a whole.
