The number of Asians in the United States has grown by nearly half over the past decade as the country looks increasingly diverse, the U.S. Census Bureau says in its study on race.

Asians in the U.S. totalled 14,674,252 as of 2010, or a 43 percent increase from 10 years earlier, according to the study released last week.

It also shows Asians who identify with only one race now make up 4.8 percent of the U.S. population.

The only other group rising at the same pace was Hispanics, whose ranks also jumped 43 percent over the past 10 years.

Growth has been much more tepid among non-Hispanic white people, whose numbers rose by just one percent in the past decade.

They now make up 69 percent of the U.S. population.

New York City’s population jumped to 8,175,100 over the past decade, according to the latest Census — but the 2.1 percent bump was still far smaller than officials had anticipated.

Mayor Michael Bloomberg and other elected officials disputed the count.

A 2009 federal survey of New York and the rest of the nation predicted the Census would reflect a 4.8 percent jump in the city’s population.

Queens, in particular, was a sore point for officials.

The Census tally there showed the borough added a paltry 1,300 people.

The borough is home to a large Filipino population.

“The Census says that we have added 166,000-odd people since the 2000 count, but we are concerned that there’s been a significant undercount,” the mayor said.

“When three boroughs go up dramatically, and the two most populous boroughs don’t, something is wrong.”

Gov. Andrew Cuomo’s office said he is still reviewing the numbers.

Asian and Hispanic populations in the Big Apple spiked between 2000 and 2010, transforming the city’s racial landscape.

But the number of black New Yorkers dropped 5 percent, the first dip in that group since 1860.

There were fewer whites, as well.

The Asian population enjoyed the biggest gain in New York, adding 247,900, a climb of 31.8 percent.

Hispanics also had strong growth and increased their numbers by 175,500, or 8.1 percent.

The non-Hispanic white population fell by 78,300, a decline of 2.8 percent.

The Census put the city’s population at 33.3 percent non-Hispanic white, 28.6 percent Hispanic, 22.8 percent non-Hispanic black and 12.6 percent Asian.

Overall, Brooklyn remained the city’s most populous borough, growing by 39,300 people, a 1.6 percent increase.

The Bronx led the city in growth with 52,400 new residents, a jump of 3.9 percent.

Manhattan’s population grew by 48,700, a 3.2 percent increase, and Staten Island added 25,000, a 5.6 percent jump.

The numbers have real-life consequences:

Funding for several federal and state programs is determined by population counts.

Astoria, a longtime Greek enclave that has begun to attract young professionals, lost the most people of any neighborhood in the city — more than 10,000, according to a city analysis of Census figures.

Population growth was mixed in New York’s suburbs.

Suffolk County’s population rose by 74,000, a 5.2 percent jump.

Nassau County saw much weaker growth and added only 5,000 new residents, a less than 1 percent increase.

Westchester added 25,700 people, or 2.8 percent.
