Stories on Brazilians leaving Massachusetts

"Brazilian immigrants are returning home, driven by several factors: failure of immigration reform, immigration crackdowns, and the worsening exchange rate between the dollar and Brazil's real."

"Brazilian immigrants are quietly packing up and leaving. The falling dollar has made it less attractive for them to work in the United States, and tightened immigration laws are making it uncomfortable to stay."

The Myth, the Math, the Sex

EVERYONE knows men are promiscuous by nature. It’s part of the genetic strategy that evolved to help men spread their genes far and wide. The strategy is different for a woman, who has to go through so much just to have a baby and then nurture it. She is genetically programmed to want just one man who will stick with her and help raise their children.

Surveys bear this out. In study after study and in country after country, men report more, often many more, sexual partners than women.

But there is just one problem, mathematicians say. It is logically impossible for heterosexual men to have more partners on average than heterosexual women. Those survey results cannot be correct.

Sex survey researchers say they know that Dr. Gale is correct. Men and women in a population must have roughly equal numbers of partners. So, when men report many more than women, what is going on and what is to be believed?

“I have heard this question before,” said Cheryl D. Fryar, a health statistician at the National Center for Health Statistics and a lead author of the new federal report, “Drug Use and Sexual Behaviors Reported by Adults: United States, 1999-2002,” which found that men had a median of seven partners and women four.

But when it comes to an explanation, she added, “I have no idea.”

The most likely explanation, by far, is that the numbers cannot be trusted.
I know, I know, it's such a shock that people lie about sex...still, I liked the article, and I'm glad missmoreland posted it. Thanks!
