In the Netherlands, 75% of working-age residents had jobs, among the highest percentages of all OECD countries. The Dutch, however, also enjoyed a great deal of personal time, devoting 15.44 hours per day to leisure and personal care — fifth highest among countries measured by the OECD. Not surprisingly, the Netherlands ranked as one of the best countries for work-life balance among all nations reviewed. Just 0.6% of employees in the country worked long hours — less than in any nation reviewed except for the Russian Federation. Work-life balance, combined with strong earnings, may have contributed to residents’ life satisfaction..

Mexico’s economy grew 3.4% last year, more than all but two other countries reviewed and above the OECD’s GDP growth rate of 1.2%. Still, Mexico is not without problems. The country’s air pollution is considerably worse than most other OECD nations. Mexico City is working hard to improve pollution after the U.N. named it the most polluted city on Earth two decades ago. Crime rates in Mexico are also notably higher than most other nations. Nearly 13% of residents 15 and older were assaulted last year, more than in any other country. Also, Mexico’s homicide rate was 23.4 per 100,000 people in 2010, considerably higher than the rate across the OECD of slightly more than four homicides per 100,000 people and second only to Brazil among nations reviewed.

Iceland’s employment rate of 80% among working-age residents led all countries. Icelanders also had the strongest support network out of all countries reviewed, with 96% of residents indicating they had people they could count on in an emergency. Still, in other areas measured by the Better Life Index, Icelanders didn’t fare as well. For one, the country’s educational track-record was mixed. Residents spent an average of 19.5 years on their education, the second most out of any nation. Despite that, the average PISA score among students, as well as the educational attainment of working-age citizens, ranked among the bottom half of countries reviewed. Iceland was also in the bottom half of countries in terms of work-life balance.
