     What brings a nation together? Of the four choices - shared values, language, history, and religion, it's shared values. In our latest poll (民意调査), seven out of 16 countries chose values as the greatest factor (因索)bringing a nation

together, and six preferred language. Both choices scored high in the poll, suggesting that our values and how we

express them are closely linked Still, history was not forgotten in some countries, particularly in Mexico and Russia.

Even Canada and the United States chose national histories as the second-most important factor uniting their people.

The biggest surprise? Not one country picked religion as its top choice. 

     Respect your elders

     In most countries, the oldest

generation considered values more important to a nation than did those who are under 45 years old.

     Do you speak Canadian?

     Language scored lower in Canada than in all other countries polled, perhaps because the country speaks two

official languages, French and English.

      Church and state

      Most people polled do not connect their religious beliefs to their national pride. Religion ranked last in

13 countries - with France scoring it at 1%, the lowest of all.
