WASHINGTON (MarketWatch) — Young millennials now outnumber aging boomers and America is more diverse than ever. So says a new report from government researchers at the U.S. Census who study shifting demographic trends. Here’s a few quick facts.

• Millennials have become the biggest generation in American history. Some 83.1 million Americans were born from 1982 to 2000, the birth years generally ascribed to millennials. They now outnumber a shrinking baby-boomer population (born from 1946 to 1964) that totals 75.4 million.

• The millennials are very diverse, but not the most diverse. Some 44.2% of millennials are classified as something other than “white,” but 50.2% of the generation of Americans five years old or less are part of a minority ethnic group. They make up the first majority-minority generation in U.S. history.

• Florida is home to the highest percentage of people 65 or older at 19.1%, but that’s no surprise. Warm weather and no income or inheritance tax makes Florida the top destination for out-of-state retirees.

But did you know the cold northern state of Maine has the second highest percentage of elderly at 18.3%? Many younger people have moved to other states in search of work or better climates, leaving behind an aging population of residents who can’t afford to move to Florida or Arizona.

• The youngest state in the U.S. is Utah, where the median age is 30.5. That means half the residents are under the age of 30.5 and half are above that age. The heavily Mormon state easily has the highest birth rate in the nation at 17.6% (2013)

• North Dakota one of five states that got younger. An oil boom has drawn thousands of young workers, mainly men, along with thousands of other to cater to their needs. North Dakota also has the second highest percentage of males, 51.3%, after Alaska.

• More women live in DC as a percentage of the population than any other state, at 52.6%. DC also has the highest percentage of blacks at 50.6%.

• As of July 1, 2014, the U.S. population by ethnicity was composed of 197.9 million whites (60%), 55.4 million Hispanics (17%), 45.7 million blacks (14%), 20.3 million Asians (6.5%) and 6.5 million native Americans (2%).
