It absolutely is NOT. it explicitly states these numbers are only useful for comparing hours worked by year in a given country, not for comparing between countries. "The concept used is the total number of hours worked over the year divided by the average number of people in employment. The data are intended for comparisons of trends over time; they are unsuitable for comparisons of the level of average annual hours of work for a given year, because of differences in their sources."
