Ethnic Diversity: Is It The Key To Happiness? (POLL)

Researchers in Britain made an interesting discovery when they asked respondents in their national Happiness Index program how often they mix with other ethnicities. Nearly half of the white population surveyed said they only meet people from a different ethnic background when being served in shops or restaurants, The Guardian reports.

The study, which was announced by Prime Minister David Cameron in 2010 in an effort to better gauge national wellbeing, also asked the 200,000 respondents how content they feel with their everyday lives, with one in 20 adults describing themselves as "completely lonely."

Though there wasn't a direct correlation made to ethnic diversity, the adults surveyed said they are more likely to be happy with their personal relationships than with their lives in general.

For researchers, the ethnicity figure shows that despite Britain becoming a more diverse society, many people only meet others of the same ethnicity. According to their findings, the least mixing appears to take place at school or nursery -- only 15 percent of white people meet other races there, and only a third of other groups.

Age also proved a factor in racial mixing as well, decreasing in older populations. 52 percent of respondents over 75 said they mix with other ethnicities, the lowest of any age group. By contrast, the greatest amount of mixing appears to take place among young people, with 92 percent of 16 to 24-year-olds saying they regularly mix with other ethnic groups, mostly in pubs and nightclubs.
