Yet more microtrends

And here's one last batch of Microtrends.

- Soft drinks are the leading source of calories in the average American diet, accounting for almost 1 in every 10 calories consumed.

- A 12-ounce can of Coke has 34 milligrams of caffeine. Red Bull has 80. A child who drinks one can of caffeinated soda experiences the same effects as an adult who drinks four cups of coffee. Restaurants are now producing caffeinated donuts and bagels.

- In 2005, the bestselling books were on average more than 100 pages longer than they were in 1995, when they averaged 385 pages.

- One million households now employ nannies, and nannies with a college degree have an average annual salary of $43,000, well over the $22,000 that the average 18-24-year-old female makes coming out of school with a bachelor's degree.

- More Americans went bankrupt in 2005 than graduated from college. Bankruptcies have more than quintupled in the last two decades.

- Employment in the nonprofit sector has grown more than business and government. 12.5 million work at nonprofits, more than double what it was thirty years ago.

- More than 30 million Americans have tattoos - nearly 1 in 4 adults.

- Messy desks are linked to wisdom, experience and higher salaries.

- In the last decade, there has been a 444% increase in the number of cosmetic surgeries performed in the U.S. But the number of people having them has risen at a slower rate, meaning that more people are getting multiple procedures.

- Heavy technology users are more likely to be extroverts (nearly 60 percent) than introverts.

- Girls are more likely than boys to use cell phones (88 to 83 percent), digital cameras (54 to 50 percent) and satellite radios (24 to 18 percent). They use TVs, VCRs, DVD players and PCs about the same. Boys outpace girls on MP3 players and videogame consoles.

- Women are now the majority of college students, law school students, voters and car buyers.

- One in 4 videogame players is over age 50. The average player is 33 and has been playing for 12 years.

- 2.2 million kids are home-schooled, more than charter school and voucher students combined.

- While college enrollment rates are up, college graduation rates are about the same, meaning more students are dropping out (over 28 million in the past decade).

- New religious movements are becoming statistically more significant than many established religious traditions; 20 million Umbandans in Brazil outnumber the world's Jews by one and a half times and outnumber Unitarians by more than twenty times. The World Christian Encyclopedia chronicles 10,000 distinct and separate religions in the world and says that two or three new ones are being created every day.
